I'd like to fly a model Hindenburg and control it with my Futaba Super 7.
I'm open for suggestions on how to ignite the thing safely. Cameras will be
rolling. :) I have 15 acres of marsh land to play with, so I'm not worried
about hurting anyone.

Not knowing how to ignite Hydrogen is a pretty good indication that you
shouldn't be playing with it.

Step out of your bubble a little bit. I've been flying rc planes for a
while and bought the Super 7 equipment when it first introduced to the
market. I want to keep it SAFE and don't have a lot of experience with
blimps. Of course I'll practice first only an idiot would blindly jump into
something. When in doubt ask a question.

BTW, when you first started to fly you didn't know much about flying, but
you learned didn't you?

don't listen to them. Coal gas is/was half hydrogen half carbon
monoxide. As I said, we filled a kids balloon with it, taped a fuse on
teh side, lit it and let go. Got to about 300 feet before it ignited. It
dodn't explode. It sort of 'whumphed' and created a nice short duration
fireball.


To explode, you need a critical fuel-air mix.

The hindenurg burned apparently mostly because the covering - fabric
doped with nitrocellulose? burned. The hydrogen didn't go up
immediately, but when it did, it just brough the thing down fast.

I'd defiitely try the party ballon and jetex fuse first, and for ***s
sake be careful. It won't blow you to bits, but it will be second degree
burns all over yer face if it goes up while you are lighting it.

Borrow a full face helmet from a biker, and gloves and leathers too.

What we did was hold the fuse out sideways, light it away from the
ballon - it was a pretty LONG fuse, and let go. It burned through teh
latex and set the gas alight quite nicely.

Early tests were done on the ground useing a tethered balloon.

Natural gas curtailed our fun shortly aftewards - this must have been
1973 or so...

You can have fun with natural gas, too. Get a large garbage bag,
preferably a cheap, thin one. Put a piece of mylar tape over the open
end. The best way to do this is to lay the bag out while it's still
flat, and put the tape along the edge with half of its width hanging off
the end of the bag. Then turn the bag over and fold the tape onto the
other side. Leave a half inch or so of the opening untaped.

Now stick a gas nozzle into the opening and fill the bag with natural
gas. When it is full, put a small piece of tape over the remaining
opening.

Get a packet of firecrackers, a pack of 16 is about right. Attach an
extra long fuse to the firecrackers and tape them flat against the bag
with about 5 layers of tape. Sparklers make really good fuses. When my
brother in law and I were doing this several years ago, we would bend
the sparkler at a 90 degree angle right where the flammable part stops.
The stem would go under the firecrackers and through the little loop at
the other end to stabilize it. The flammable part would come up from
under the firecrackers to stick straight out, perpendicular to the face
of the balloon. The firecracker fuse was taped to the end of the
sparkler with one layer of scotch tape. (generic name for
office/desktop tape for you non-US readers) The detonator always ends
up on the bottom due to weight, so the sparkler will naturally rest in a
position pointing away from the bag and the firecrackers.

Once you have the delay fuse in place and the firecrackers taped firmly
to the bag with several layers of tape to direct the blast inward, you
can light it up and let it go. Even more fun is to make about ten of
these garbage bag balloons and get 9 pieces of mylar package tape about
3 feet long. Stick about an inch or two of the tape to the first
balloon, then stick an inch of the other end to the next balloon. Then
stick another piece of tape to the bottom of the second balloon and
attach the third, and so on. The last balloon would have the
firecrackers on it. One balloon is fun, but ten balloons is even more
fun.

The net effect of all of this is that you get a bright, pretty light
floating away from you for a minute or so, depending on how long your
sparkler is. Then you hear the popping fireworks, then you see an
orange mushroom cloud about 3 feet wide. If you have a substantial
chain, you can get a really BIG ball of flames. The funny thing is that
after the firecrackers, you don't hear anything. It's really not
unsafe, either. The plastic melts, the gas burns, and you get little
wads of melted plastic falling from the sky. We set off a chain of 7
one evening and made a light in the sky at night that lit up an area the
size of a football field. Then the sherrif came around looking for a
fire. So we went in the house.

Oh man, putting natural gas into garbage bags sounds sooo cool.
Wish I would have thought of something like that when I was a kid.
When I was a kid in the 50s, we lived in the country and didn't have
natural gas. What I did was make pounds and pounds of gun powder.
Boy did I have fun with that. It is a wonder I have all my arms and
eye sight. Once I set off 4oz of powder under a 5 gallon paint can.
You know the heavy steel ones. When it exploded, the can went about
100 feet into the air. The can was all domed. What fun.
I hear a knocking at the front door now. Probably the ATF.
What fun.

I used to tie M-80's to a rock, light 'em and drop into a 30 gallon
trash can filled with water. First couple were great! About 20 gallons
shot straight up! Third one blew out the seam:-(
Needless to say, I bought mom a new trash can.<g>

My brother & I tied a load of string to a Co2 cartridge, poured lighter
fluid on it & lit it. Wow, it shot about 75 or so yards away, went
through a neighbors window, screen, inner window, and imbedded into her
kitchen cabinet! That one cost us big time! Least nobody got hurt.

That one sounds like fun. If I were to do it I would build a
stabilizing body for the cartridge to attach to. Probably something
with fins on the end so it could shoot up like a rocket. I wonder how
high it would go. I wonder if there is any guarantee where it would
split...

A friend of mine found a .45 bullet but had no gun to shoot it from. So
he did the next best thing. He put it on the end of his BB gun and
wrapped a piece of duct tape around the end of the barrel and the shell
casing to hold it in place. Then he turned his head away, pointed it in
the air and shot a BB to hit the end of the shell. Sure enough, it
fired. He never found the bullet, but he got a piece of shrapnel from
the shell embedded in his thigh.
He didn't want to tell his mother because he would get in trouble, so he
got a lot of ice to numb the area and tried to perform surgery on
himself with an X-Acto knife to remove the fragment. I think it ended
up staying in there because he couldn't make himself cut into his own
leg.

Sounds like my homemade rocket. I had a left over Model Rocket engine.
Rather than buying a new rocket, I glued carbord fins to it. Well it went
straight up for about 10 ft, and then it changed directions and went
horizontal right through the neighbor's window.

As a young kid ( I'm still a kid, just not young anymore ), my friends and I
would pull the man hole covers off the sewer in the middle of the street at
night. We would pour maybe a quart of gasoline into the man hole, splashing
it onto the sides, not into the water at the bottom. Then we would put the
cover back in place and go play for half an hour or so. We'd come back and
one of us would light a match and drop it into a hole in the cover. I seem
to remember the neighborhood record for blowing man hole covers was about
4'.
Nothing like good clean fun.

That's a good one! I never did this kind of stuff because I didn't live
in town. We made homemade gunpowder instead. We never got it to
explode, though. It would mostly just fizzle. We used to roll it in
paper with clumps of dog hair, about the size of a cigarette, and light
one end to make a really nasty smoke/stink bomb. My brother threw one
out the school bus window, but it landed right at the feet of the
teacher on patrol duty, so he got suspended.
Another favorite thing to do out in the country was to put a bottle
rocket head-down in a fresh cow pie. It would have about a quarter inch
sticking in, and the rest sticking up. Then we would call a
town-dwelling friend over to watch the spectacle, and light the fuse.
Back in those days the bottle rockets actually had some oomph to them
and were powerful enough to create quite a substantial cow pie blast all
the way up to face height on a 12 year old.

big snip

Robbie, boy does this bring back memories. I'll bet I know why your
black powder would not explode. I mixed mine with water and cooked
it until it was dry. Let me tell you how I almost set our house on
fire.
I use to experiment with all sorts of formulas for gun powder. To
test the power of the batch, I would take a small pinch of the powder,
put it on the basement floor and set it alight with a match. I could
tell how powerful it was by the way it went off and the residue it
left. Any way, I had set the can of dry new powder on the basement
floor and took a pinch and (like a dummy) put it on the floor next to
the open can of new gun powder and set it off. As you know, it sparks
and smokes like crazy. As I set it off, a spark went into the open
can of powder and it went up like the biggest roman candle you have
ever seen. I am talking about a whole pound of black gun powder. The
powder flame went up to the ceiling and clear across the basement.
With in seconds the powder can was red hot so I couldn't take it
outside. (We had an outside door to the basement) I was terrified. I
knew it wouldn't explode because it wasn't contained but the whole
basement (it seemed to me) was full of flames and smoke. But thank
goodness it didn't catch anything on fire. I think it took only about
ten or fifteen seconds to burn the whole pound. (Good batch) To this
day I can still hear my Mom calling down to the basement and ask if I
was burning anything. The basement was so full of powder smoke I
could hardly see. Good thing she didn't come down to the basement or
I would have lost my driving rights for life.
The dumb things we do as kid. These are the things I did when I
wasn't flying my rubber powered planes.

Long story, sorry

I'll tell you one that I did about two years ago. I'm always looking
for ways to save money, so I taught myself how to rebuild saxophones. I
had taken my antique alto sax to a shop to be adjusted and put into
playing condition and it ended up costing me $200. I figured that I
would be better of on the receiving end of that amount of money, so I
decided to learn to do it myself. So I bought an antique baritone sax
on ebay and started my reconditioning project. One thing that saxophone
repairmen use a lot is an alcohol lamp. It's used for melting the
adhesive that holds the pads in the cups. An alcohol flame is not
extremely hot compared to other fuels, and it leaves no soot on the
keys. You will see home made alcohol lamps in any shop where there are
woodwind repairmen working, and they're usually made from old peanut
butter jars and such. You just make a hole in the lid, put a threaded
tube through it (from the lamp parts section of the hardware store, I
think it's called a ferrule), and then fasten it in place with a nut on
the inside of the lid and one on the outside. Then you roll a wide lamp
wick into a spiral and stuff it through the tube, leaving the end to
hang in the alcohol. Just the very tip of it will be at the top of the
tube. Fill the jar with alcohol and you get a nice little flame about a
half inch tall at the top.

I decided to make one of these, but I hadn't closely studied the ones
that I had seen. I simply cut a slot in the lid and pulled the wick
through. I put about two inches of alcohol in the jar, lit the wick and
it instantly exploded. The problem was that the wick was just loose
enough in the slot to allow the flame to travel into the jar. This was
a very bad thing. The jar exploded in my hand, causing glass to fly
everywhere, and flaming alcohol fell on my leg and ran out the bottom of
my pants where it burned off of my ankle.

Now here's the worst part. I remember the early brainwashing that I
received in school over 25 years ago. When you're on fire, you are
supposed to roll on the ground, right? So I ran up the half-stairs to
the door from the basement to the yard. But it was locked.
(Incidentally, my mother-in-law just a week before had told me not to
keep it locked, in case of fire. I actually laughed at her.) I spent a
moment or two thinking of what to do while my leg continued burning, and
then it suddenly occurred to me that the best thing to do would be to
get in the shower, which I did. That put the fire out instantly. Then
I went back to the basement and realized that the alcohol had set a box
of balsa scraps under the table on fire, and the flames had spread to my
stereo speakers. We were able to put the fire out very quickly, and the
only loss was a set of venetian blinds, a box of scraps, and the
speakers.

I suffered third degree burns on my ankle (in my own estimation. I
never went to a doctor.) It hurt a lot for about a month, but I took
really good care of it and it healed nicely. I learned something
important, though. Always be sure to try new things outdoors if they
involve flammable materials. I know that this story probably makes me
sound like a reckless maniac, but this is the only really risky thing I
have done. I'm actually a very careful person. You may recall that
whenever the discussion turns to propeller accidents, I'm always the
most outspoken advocate of simple safety measures. I know for sure that
6 ounces of flaming alcohol will make you really careful!

Epilogue:
I made a $400 profit on the baritone sax, and now I rebuild and repair
saxophones part time for a local store for some extra cash. I was able
to salvage one woofer from my stereo speakers, which I used in a tube
powered homebuilt Fender replica guitar amplifier. Last summer when I
bought all of Tom Runge's RC stuff, Donna Runge gave me a nice set of
speakers, which I now use. And I totally eliminated the outside door
from the basement and put a half bathroom on the main floor in place of
the stairway. Now if I catch on fire I'll go to the shower first!

As the statute of limitations is long past, I guess I can tell this tale.

My buddies and I used to hang out at the local railroad crossing, the guy
used to let us crank down the gate and step on the pedal that rang the bell
and worked the lights... Great fun for a group of 12 year olds.

Our day was made when one day the phone rang, it was a gate guy from up the
line reporting a "hotbox" ( a smoking bearing on one of the wheels). We
accompanied him as he set out a nifty thing called a "torpedo". It was a
square pack of some explosive. It was held to the track with some lead
straps and the explosion sequence alerted the train engineer he had a
problem. (best I remember it was a series of three of them spaced about 100
feet apart - 55 years later I may be a bit hazy on the details)

Noting the location of the "torpedo" stash, we diverted the gate guys
attention while one of them was purloined.

We headed down town and strapped it to the trolley track, failing to
understand the physics of the difference between an 80 ton locomotive and a
2 ton trolley car.

We hid in some bushes and awaited the trolley car, it went off with a
bang... and man what a bang, it blew the wheel off the trolley car and
through the window of a furniture store that fortunately closed.

We sweated for months that we would be discovered, but luckily for us, we
were not.

Is there anyone else a crazy as I was? Oh, I forgot, I almost set our
house on fire too.
I grew up in south Texas right next to the Mexican border. We used to
be able to get giant firecrackers in Mexico. These were made from
folded newspaper and were triangular, like the little paper footballs
that schoolboys play with in study hall. The major difference is that
the firecrackers came in several sizes ranging from large (about 5
inches long) to enormous (about 24 inches long). They had long fuses
protruding from the long edge. Believe me, you don't want one of these
things with a short fuse! We had a concrete block (the kind with two
large holes, for building walls) lying on its side in a field, with the
holes pointing up. We put a medium firecracker in the hole and put an
old hubcap on top of it. This thing blew up with a boom that sounded
like a large bomb going off. The hubcap flew about a hundred feet high,
but then we noticed that the concrete block was in several pieces.
Another entertaining feature of these firecrackers is the large cloud of
shredded paper that results from the explosion.

When I moved to Missouri in 1996 I brought a few of these Mexican
firecrackers with me. We went out to my uncle's farm in Kansas for the
4th of July. My uncle was about 75 years old at the time, a country boy
from the Great Depression era. As a preacher he used to take the church
youth group places riding in the back of his pickup truck, back when
nobody thought twice about those things. He also told me about a
sausage breakfast they once had as a church youth fundraiser back in the
good old days. He procured a hog, shot it in the head, and the kids
turned it into sausage. If you did that today you would probably get
sued. Anyway, his farm was just the place for a giant Mexican
firecracker. We put it in an old defunct beehive and even got the
explosion on video. It rained chunks of wood for several seconds.
Actually the best part of the video is where you see my nephew running
for his life after he lights the fuse.

I did something similar, except with calcium carbide. I'd put a piece of
the calcium carbide in the can, with a little bit of water. I'd put the
plastic cap back on, but with a small pin hole in the top. Then I'd take a
long stick with a lighter attached to the end and dangle it over the lid.
KABOOM. :)

I did something similar, except with calcium carbide. I'd put a piece of
the calcium carbide in the can, with a little bit of water. I'd put the
plastic cap back on, but with a small pin hole in the top. Then I'd take a
long stick with a lighter attached to the end and dangle it over the lid.
KABOOM. :)
That's a good one. But where do you get calcium carbide?

My nephew who works in a restaurant told me what you can do with dry ice
from the delivery guy. You put some chunks of it in a plastic 2 liter
soda bottle and screw the lid on. When the pressure gets high enough it
explodes loudly. He also put some in a sink, added hot water, and then
stirred in some liquid soap. He said he had a column of smoky suds
coming out of there like a volcano. He had to keep scooping them onto
the floor with a piece of cardboard to keep them from oozing all over
the bar!

I go down to Amish Country to the local store. It's used in old miner's
lamps, so that's why I believe the Amish stock it. Calcium Carbide makes a
great stink bomb as well. I brought a piece into school one day and we
didn't have any water at the time so my buddy spit on it. It's not till you
set it off in a confined area that your realize that the acetalyn gas it
gives off smells like Garlic, in a matter of minutes the whole room
evacuated gagging.
My father used to use it for fishing when he was a kid. He'd drop a piece
in a beer bottle with a rubber stopper cap and toss it into the river. The
fish would come up to to see what it is and then kaboom. The shockwave
would either kill them or knock em unconcious. I tried it with a bottle of
Grolsh beer, but the glass bottles today are a lot thicker and can handle
the pressure. After a few minutes the gas started to escape around the
rubber stopper and proppelled the bottle through the watter at about 20mph
all the while making this cool whistling sound.
A friend of mine told me a different 2 liter bottle method, he drank about a
quarter of the coke out of the bottle and then pour in some salt. The salt
would cause the CO2 to bubble out of control and blow up the bottle.

I grew up & live out in the sticks here in Idaho. One of my neighbors, who
is a retired farmer, had a problem with a gopher out in his little pasture
out behind his house. He'd tried for some time to trap the critter, with no
success. Another neighbor told him about using propane to smother the
gopher, as it is heaver than air & would settle to the deeper areas of the
gopher holes. This sounded like a great idea, so he dragged a 20 lb propane
bottle out to his pasture, & stuck a hose down the hole. After letting it
run for a good 10 minutes, he decided that maybe it would work even better
if he lit it off. About half an acre lifted up several feet, & afterwards
looked like it had beeen tilled. Rattled windows for a block in each
direction. He did however achieve his objective.....no further holes.

Back in the 40's calcium carbide was available from any hardware store as
fuel for miners lights (also used by night hunters). I used it to make a
canon which worked remarkably well. But I was a complete idiot in those
days.
Made gunpowder, gun cotton, and other items up to and including dynamite.

Got interested in thermite and welded the gates to Harvard yard shut -
students and facility had to use ladders to enter Harvard the next day. Also
welded a subway train to its tracks in Park street station in Boston. It's
very lucky I was never caught or killed.

Then I got drafted for Korea and where did they send me - Demolition school
at Fort Belvoir for 6 months. They taught me how to make explosives out of
just about anything.

I would NOT recommend anyone playing around with this stuff as its only luck
that I was not maimed or killed.

Step out of your bubble a little bit. I've been flying rc planes for a

Not knowing how to ignite Hydrogen is a pretty good indication that you
shouldn't be playing with it.
He doesn't need hydrogen, it's been proven that the fire was the skin
burning. The treatments of the skin result in a chemical equivalent to slow
burning gun powder.

Sure the hydrogen burnt, but it was the big bang it would have been if the
hydrogen was ignited internally.

Most blimps use helium now days and I don't believe that will burn. A

First, the idea if igniting a bag of hydrogen sounds...well....lets just say i have my
fathers voice stuck in my head yelling "WHAT WERE YOU THINKING"
having said that, if you feel you can do it safely, i'll take you at your word.
Stroll down to your LHS and get a pack of Estes model rocket engine igniters. You should
simply be able to rig a switch (and a safety switch!) closed by a servo. you could power
it from a separate battery or maybe from your receiver pack, but the igniter may draw too
much current - thus making your radio twitch out. That shouldnt matter because she will be
exploding while twitching....shouldnt notice it.

Lastly, i dunno if your going to get the scale appearance you are going for. The Hberg
'burned' because there was sooo much hydrogen that lack of oxygen was the limiting factor.
I suspect that a small balloon will just go "BANG".
Oh, and lemme know when you post whats left of your radio on ebay. :P

Actually, was it really "a lack of oxygen" that caused it to burn slowly or
did the hydrogen explode with a pop, and the structural components
(framework and skin) start to burn like a regular old fire? I can't imagine
there being a lack of oxygen at 30 something feet....

Hydrogen burns with a clean, steady flame. Hydrogen mixed with oxygen will
explode with a ferocity dependent on the ratio and eveness of the mix.
A large ball of hydrogen might burn at it's periphery but delay combustion at
the centre until oxygen could get there. But the lighter than air gas rising
coupled with the gas vortices caused by burning would I imagine cause pretty
rapid and fierce combustion of the hydrogen leaving the structural components
as you suggest. Speed is all relative.

In any case I wouldn't like to be close to the experiment in case any pointy
bits became projectiles.

give me grater range. I need to check legalities yet and see if I can get

Some of them appear to have some factual origins, but I suspect that

a lot of research to track tall tales back to their source, such as a

We did an experiment in our science class once, using hyrdrolisis, we
separated water into hydrogen and oxygen and filled them into balloons.
They both exploded with a pretty good bang, I can't remember which one was
louder. When we filled a balloon with 50 percent hydrogen and 50 percent
oxygen the explosion shattered a window in the room, and caused the teachers
from other classrooms to come running in to find out if everybody was OK.

Recreating the actual way the airship earned it's demise will be almost
impossible because of the way you would have to control the gases in an
attempt to duplicate the original and how it all started and then finished.
The original started when a vent at the front of the top fin gave off
gases that flowed back and starboard (an intentionally designed feature)
during the landing phase of it's last flight. It was ignited by static
buildup from one of the skin sections that wasn't properly grounded (not
intentional). The ungrounded skin section(s?) were "hot spots" just waiting
to arc with something nearby... and they did. You're also going to have to
install the multiple and separate envelopes that made up the structure of
the lighter-than-air bouyancy system.
I think what you're trying to do will give you nothing more than a
"bang" followed by a fireball which is NOT how the original happened. But
good luck, I think anything that blows up and doesn't hurt anybody is
nothing but a load of fun.
For ignition, I'd go with a sparking device operated by radio control.
Something like what's used in most barbeque's to ignite the propane. Most of
them only need a single cell AA battery for power.
For a standby fire extinguisher, I'd recommend a pumper from the local
fire department. Oh, and be ready to answer a lot of questions that might be
posed by the Department of Homeland Security :-)

I'd like to fly a model Hindenburg and control it with my Futaba Super 7.
I'm open for suggestions on how to ignite the thing safely. Cameras will be
rolling. :) I have 15 acres of marsh land to play with, so I'm not worried
about hurting anyone.

Recreating the actual way the airship earned it's demise will be almost
impossible because of the way you would have to control the gases in an
attempt to duplicate the original and how it all started and then finished.
It was more a case of materials than gases. The skin was essentially a slow
burning gunpowder.
Post by MJC
The original started when a vent at the front of the top fin gave off
gases that flowed back and starboard (an intentionally designed feature)
during the landing phase of it's last flight.
Never heard this but I won't dispute it.
Post by MJC
It was ignited by static
buildup from one of the skin sections that wasn't properly grounded (not
intentional).
A disputed fact but one the majority believe to be true (ie. some form of
static discharge was the ignition point).
Post by MJC
The ungrounded skin section(s?) were "hot spots" just waiting
to arc with something nearby... and they did. You're also going to have to
install the multiple and separate envelopes that made up the structure of
the lighter-than-air bouyancy system.
He wants it to burst into flame so it isn't necessary to duplicate the
design exactlty.
Post by MJC
I think what you're trying to do will give you nothing more than a
"bang" followed by a fireball which is NOT how the original happened. But
good luck, I think anything that blows up and doesn't hurt anybody is
nothing but a load of fun.

For ignition, I'd go with a sparking device operated by radio control.
Something like what's used in most barbeque's to ignite the propane. Most of
them only need a single cell AA battery for power.
Wouldn't it be better to ignore the whole hydrogen argument and simply go
for a burning skin. Even if you don't believe this to be the case, it's what
visually appeared to be significant.

For a standby fire extinguisher, I'd recommend a pumper from the local
fire department.
Some decent sized extinguishers and access to the planned crash site would
help. Those silly little car extinguishers won't be enough if it starts a
small ground fire.

I'd do that to some extent.

What *I* would do is get some party balloons, and fill them. And hope
they stayed filled while...

...I glued them with CA into a balsa and doped tissue framework that
came apart in the middle...

..and attach my fusewire and match head 'detonator' roughly where the
orginal fire started...

..ballast the thing for _slightly_ heavier than neutral bouyancy...

..take it up 'on the planes' and then bring it in to land...

...detonate and film it slow motion.

Balsa and doped tissue burns remarkably like the footage Ive seen of the
Hindenburg, and leaves a nice glowing red skeleton...

Sounds like a good idea! I once built a tissue paper hot air balloon that
got a little close to its heat source and caught fire. Pretty spectacular!
You might try an accelerant of some type on the tissue to make it burn a
little faster...

An interesting thing to try would be to fill about 20 ballons with Hydrogen
and then put them into a big plastic trash bag. Let the whole bag float up
and ignite. The individual balloons could be coated with something to cause
a delay in burning.

I worked in an auto repair shop years ago. The owner used to take soda cans
and fill them with a mixture of oxygen and acetylene and ignite them with
the torch he used to fill them. The oxygen/acetylene mixture would launch a
soda can a hundred feet or so. He used to have great fun doing this but it
all came to a screeching halt when the oxygen/acetylene mixture exceeded the
strength of the soda can. Luckily, we only had to pull one piece of aluminum
pop can out of his fore head, he was trying REAL hard to be a Darwin winner.

I used to just let acetylene out of the hose into thick grass, then
throw in a match. Acetylene is heavier than air, so it didn't go
anywhere. I used to get a really good explosion using that method, but
it was hard to predict where the acetylene was going to go. That
wouldn't work around here because the grass is puny. They have nice
thick Bermuda grass in Texas.
I also used to try to come up with ways to blow up ant colonies. But I
never made the acetylene connection. The large red ants in south Texas
make a network of tunnels about as big around as a pencil, and they all
come out in one big central hole. I'll bet you could stick a torch tip
in there and run a light stream of gas for a few minutes and then blow
the entire network up.

This thread has me laughing to tears. I am so very glad *I* am not the only
crazy here!

I found that an M-80 buried in the dirt would 'launch' the 4 inch covering
asphalt 10 to 12 feet in the air. Decided to get serious and started
building a launch vehicle. Got me in lots and lots of trouble when my
partner in crime's younger brother lit off my fuel supply. Also led to
being caught breaking up shotgun shells for the powder. Found out about
primers real fast that evening too!

I used to use gasoline on the ant colonies and it did not blow up my yard!
But I did notice that the grass did not grow back the next year...

tel me about it.

I found this thing in amongst my fathers stuff. Couldn't work out what
it was, thought it was just a bullet, but I couldn't see why it had a
brass end on it, so I put it in the vice and hacksawed the end off....

...you've guessed it. It was a live .22 round! the bang deafened me for
a few hours.


..another time I decided to make a rocket out of weedkiller and sugar so
I epoxied some washers on to an Al tuibe to make a nozzle, filled it up,
sealed the other end, and put it on a ramp or maybe hung it on the
washing line, stick some jetex fuse in teh end and lit it.

Its fizzed a bit, shuddered and then detonated with an almighty bang.

I found (what was left) of the tube months later when fall came, right
down the other end of the yard, all twisted and crumpled. Thank god it
didn't 'bang' in my direction.

Nother time a friend built a caonnon out of steel wall tube and a little
5mm ball bearing, mounted on a bit of wood for sighting. We used powder
from a firecracker - only a small one, and found a seclude place by some
tennis courts to play with it. We aimed it carefully at the tennis court
makers cast plaque about 30m away, and set it off.

We had expected a bit of a recoil and a bang..and were dissapointed
until we went up to this 1/4" casting and saw a 5mm hole punched clean
through.

My friend went all quiet and said 'I think thats probably enough really
isn't it?' I agreed. :-)

My high school chemistry teacher had a very small brass cannon in
class. He used to pack black powder in it and shoot rubber stoppers
across the room. He said he had a bigger one at home that would shoot
green oranges several hundred feet. He had another one that would shoot
beer cans filled with concrete.

This was the same guy who told us about plastic bags filled with
methane. We actually made some in class. He used to use drycleaning
bags with the end ironed shut. I added the modern innovation of cheap
garbage sacks sealed with tape, and sparklers for fuses. But this guy
was nuts. He said that the principal used to come up to his room to see
what was going on, but finally gave up. By the time I was in his class,
the principal knew he should just stay away.

Our similar experiment resulted in a screwdriver blowing a hole through my
buddy's garage roof and permanently embedding cigarette filter (packing)
into the web of skin between his thumb and hand. We decided it was time to
quit right about then.

I used to cast metal toy soldiers as a kid, one of the molds was of an old
mortar style cannon. about half an inch in diameter and 2 inches long,
including cannon balls. One fourth of July I got the idea of making it a
functioning cannon. I drilled a hole down the center of the barrel big
enough to fit the cannon balls. Then I drill a small whole for a wick. I
used the gun powerder out of 4 lady fingers and packed it in with wadding
made out of the wrappers. I put a canon ball in and lit it. Those little
wicks go fast, and in the basement the bang is pretty loud. I thought I was
deaf for a few minutes. Since nothing was holding the cannon it when flying
backward to one side of the basement. It took me a few minutes to find the
cannon ball, because it was pressed almost completely flat against the
cinder block wall. I could fire the cannon about three times before it
became so deformed that I had to cast a new one.

I turned a nice aluminum cannon in metalshop, complete with cast support brackets. I
drilled its bore and cut some 3/8" round steel stock to about 3/8" long and drilled a
1/16" hole through the bullets. I just fed the fuse of a black cat through the hole in the
bullet, put the bullet/firecracker in the muzzle and light. a quick tap would drop the
thing down the barrel and give you about 1 second to aim.
Not too bad, it would shatter glass bottles, plates, and put nasty dents in street signs.
And it looked way cool too.

I have a far superior project in mind. Makes a Hydrogen explosion seem like a good idea.

Ive been lurking far a bit gathering info on a future 1st plane purchase. Me & the boys at
the office wanna pitch in a few bucks each for something we can waste our lunch hour with.

They start talking about mounting a wireless camera to the tail of this un-named future
plane and a bank of light aluminum .22 barrels under the wings. The whole idea is to do
some 'interactive' duck hunting. After that brainstorming session i had a whole new
respect for the darwin awards.
It should frighten you that people as dumb as us work at a well respected bridge & highway
engineering firm.

It doesn't surprise me.

Not to be a wet blanket or anything... Although I appreciate a good
explosion, and I have done all kinds of crazy things that would make
most people wonder why I am still alive today, I draw my line at radio
control bullets. I have experienced radio interference and would not
want my rudder to go left all of a sudden while the bullets decide to
come flying out.
Not only that, but strictly on the grounds of practicality, you would
never be able to hit your target from an RC plane, unless the plane was
flying directly away from you and the target was in front of you in a

hehe. Something about birds-of-a-feather comes to mind.
I have a far superior project in mind. Makes a Hydrogen explosion seem like a good idea.
Ive been lurking far a bit gathering info on a future 1st plane purchase. Me & the boys at
the office wanna pitch in a few bucks each for something we can waste our lunch hour with.
They start talking about mounting a wireless camera to the tail of this un-named future
plane and a bank of light aluminum .22 barrels under the wings. The whole idea is to do
some 'interactive' duck hunting. After that brainstorming session i had a whole new
respect for the darwin awards.
It should frighten you that people as dumb as us work at a well respected bridge & highway
engineering firm.

Hide a balloon filled with acetylene inside...it'll blow up real good.
Careful! I've played with them before and they can be very dangerous. One of

You got that right. You wouldn't have a fireball. You would have an
explosion with little bits of receiver, nicads and servo flying at high
speeds. I don't think I would want that unless the little Hindenburg
was at least 30 yards away.

I'm open for suggestions on how to ignite the thing safely. Cameras will be

about hurting anyone.
beebn there, done that.

A small piece of fusewire (<5a) connected via e.g. an electric motor ESC
to any decent Nicad will glow white hot in under a second, and burn out.
You can wrap that round many thugs - but match heads used to work for us
in our pyrotechnical days.

Jetex fuse is also useful. Coal gas filled ballons were sent up with a
lit piece of Jetex fuse taped to the side.

Courtney,

I'm sure safety is first in your mind, and and you realize setting off
explosives with our radios CAN be dangerous. Just having the wrong servo
"blip" when you turn on the Rx could blow this thing up...

Dan Stevens in Albany Ga. built the 22' B-29 that Mac Hodges flies, and it
carries a small rocket powered version of the Bell X-1 that is lit off after
being dropped at altitude..

Email me off the list, and I'll put you in touch with Dan.. He may have
some tips you could use...

Cheers,

Bill

Will all the electrical components in close proximity to the hydrogen for

If you want to shoot video that looks like the real thing, make a
flammable body filled with helium. Hydrogen burns with an invisible
flame, so you couldn't see it in the Hindenburg film anyway.
Play the video back at low speed to make the small blimp look like the
full sized fire.

Right. That's why I mentioned that you can't see burning hydrogen
anyway. The flames you see in the Hindenburg film are from the airship
itself. If you have a flammable structure, you can fill it with helium
or hydrogen and it will not matter because you will have visible flames
only from the frame and covering.

If you fill it with methane it may float, but it would have to be very
large to get enough methane to lift the ship. Get a periodic table
online and check atomic weights. H2 weighs half as much as He, and it's
not too hard to make. Methane is readily available, but it will have a
very unrealistic orange sooty flame. Personally I'd try hydrolysis and
see how hard it is to come up with some hydrogen, just for fun.

Hydrogen filled balloons ignited in air do burn with an orange flame,
and make quite a loud bang. Here's a link to a picture of me doing a
demonstration, igniting hydrogen filled balloons. This is no slow burn
a la Hindenburg. The picture taker has to be quick!

I ignite them with a candle attached to a meter stick, at arm's length,
and I am wearing safety glasses.

Let's be careful out there!

The balloon I'd say.

Orange flame is indicative of red hot carbon soot. Get that from any
hyrdocarbon.

Actually, the balloon doesn't usually burn, and very little is even
melted. The fuel/air mixture is not optimal, so there is a lot of
heated hydrogen and air that probably gives off the orange color. There
are also lots of other elements, such as sodium, on the surfaces and as
impurities that will emit light when heated. If you had a hydrogen
flame with just the right fuel/air mixture, it probably would be nearly
colorless. A gas stove flame should be a blue color, indicating the
proper mixture. If there is not enough oxygen from the air, there will
be heated carbon particles which give off an orange glow, as previously
pointed out. In this case, there's no carbon except in the balloon, and
possibly from impurities, though.

Incidentally, there is a huge difference in the bang produced if oxygen
is introduced into the balloon along with the hydrogen. In my demos,
there is only hydrogen in the balloon, and the oxygen comes from the
surrounding air. This makes a loud boom, but nothing like if you put
the hydrogen/oxygen mixture in the balloon. If you do this, hearing
protection is a must! Again, please keep safety in mind!

It makes an intense flame about a foot high. It's the most amazing
thing because a ping pong ball is about the most innocent thing in the
world. You'd never guess that it could have so much fire stored in it,
just waiting to come out and burn the hair off the back of your hand.

No, I grew up in McAllen, born in 1968, gaduated in 1986 with a class
full of crazy people who liked to blow things up, and then I moved away
in 1991. I actually learned about the ping pong ball from a guy at
Texas Tech in Lubbock.

The kid with the .45 round on the end of a BB gun was Chad Garcia, a
classmate of mine. He also had a propane tank in his garage, like the
ones you put on a gas grill. I don't know where it came from, but it
had a hose on it with a super flame thrower nozzle on the end. The
opening was about 4 inches across, and it would shoot a flame about 2
feet long and 6 inches in diameter at its thickest point. We used it to
melt light bulbs and anything else we could find.

Chad and some friends actually got pulled out of class and arrested
during our senior year. They had heard some stuff from the crazy
chemistry teacher of course, and tried to make pipe bombs. They sealed
liquid detergent and brake fluid into PVC pipes. The story was that if
you freeze the bomb then it would explode when it thawed. But after
they ran their mouths too much, and the bomb squad was sent from San
Antonio, and they were arrested, the chemistry teacher mentioned that
they would never blow up anyway. He had left out a key ingredient,
because he knew these goofballs would try to build one.

Another thing that Chad did was steal a chunk of potassium from the
chemistry lab. He and a friend were planning to throw the metal into
the municipal swimming pool after school to watch it burn. So they took
the potassium from its jar of protective oil, cut two pieces off,
wrapped them in brown paper towels, and put it in their pockets. Next
period in study hall, Chad's potassium started burning. He ended up
running down the hall screaming because his leg was on fire. The school
nurse wanted to throw water on him, but he had to convince her not to.
He was in the hospital for a month.

I'm sure Chad would have liked the exploding man hole covers.
