Here is a lovely gasoline flame thrower.
What you need are 2 empty propane fuel tanks (like the kind you
use for a torch). The valves are drilled out and and a hose is
connected between the two of them. One is filled with gasoline
and the other is filled with compressed air. A hole is drilled in
the bottom of the gasoline tank and a hose from that is run to
the gun. The tanks are attached to straps and worn on your back.
The gun is made out of a blowgun (these are used in machine shops
and can be found at Fleet Farm) attached to A copper or steel
pipe of about 3 feet long. A propane torch head is welded to the
pipe so that the gas being expelled ignites. A small propane tank
is attached. If you can get high enough air pressure you can use
napalm and that is cool because it sticks to everything and burns
hot.
If you don't like the idea of shooting gasoline, an idea is to
use a propane tank without a regulator. Stick a nail onto the
valve to get the propane out really fast. Not to say that either
idea is safer...

Date: Fri, 11 Apr 1997 From: jica-uk@dircon.co.uk When I was 12 I
got a water fire extinguisher of around 3 US gallons, unscrewed
the top, took the water out, filled it with petrol, hit the
button and chucked a lighter through the spray, wham!
Flame-thrower! 14 - 16 foot flame. ultracool. But the problem was
turning it full without dribbles and getting burnt. The jet
wasn't very fine either. I did this twice and got thrown out of
school. My friend Tommy Clarkson did a home-made firework party
which consisted of various methods of exploding propane
canisters, the best (and nearly lethal one) was to set up little
gadget used to launch tin-can targets for skeet shooters, it used
a .22 blank to launch a steel can vertically. Tommy put a butane
canister on it and set the gadget in a vice, pulled the cord, up
it went, we shot the can with steel shot, ka-boom! However, the
first two butane cans ruptured on launch with quite frightening
results (shards of tin can metal whizz everywhere.
Date: Sun, 11 May 97 From: RIDERDAN@msn.com I made similar things
when I wasn't as aware of my own mortality as I am now. I've got
a few suggestions if your interested. use old fire extinguishers
for your fuel tank, larger tanks can handle up to 250psi. the
valve body has standard pipe threads for the pressure gauge and
nozzle, and it has a siphon tube built in so you don't have to
turn it upside down. I also like to use co2 to pressure the tank,
this is a safety precaution, when you run out of fuel the last
bit of air / fuel spray can flash back into the tank. I also used
a torch as the pilot flame, I had tried other things but they
wouldn't didn't stay lit or didn't light the fuel. keep a wet
blanket nearby in case something goes wrong, gasoline is the
worst thing to get burned by, trust me I know.

I got this new design for a flame thrower out of a supersoker
Xp-75. Here is how you make it:
Materials: Supersoker XP-75 Metal Coat hanger Short candle
(untapered) Lamp Oil
Procedure:
1 Take coat hanger, wrap around nozzle of gun
2 Insert candle into coat hanger so that wick is directly in
front of nozzle
3 Fill water reservoir with lamp oil
4 Pump up squirt gun. Make sure that oil comes out in steady
stream,NOT IN A MIST
5 Light candle,pull trigger,have fun

I would think that a home/garden sprayer,that is,a container with
a pump on top and a hose with a "trigger" you pull to
make the liquid come out would make a great flame-thrower if the
container was filled half-way with gasoline and pumped about 15
times. garden sprayers are sold at most garden or hardware stores
and are used to disperse fertilizer or bug spray into your crops.
here's my plans (note: I just came up with this today and have
not tried it yet)

I have built a flame-thrower as Snoboader3@aol.com said in his
email, and it works great. I have gotten up to about a 13 ft.
flame, with almost no danger to myself. As a lighting mechanism,
I used a small rag soaked in gasoline, then duct taped to the
nozzle, such that only a small portion of the rag is exposed.
just light the rag and then pump and spray. Also, my friend owns
a high pressure sprayer, and I have seen him get up to about a 30
ft. flame on it.

This is far more advanced and costly use scuba diving tanks
unscrew the top of one of them and refit it with a double
threaded 3/8 or 1/2 opening. keep the other a scuba tank so
filling it with air wont be a problem.grab a hose from a
regulator [diving] and attach it to the compressed air tank. take
the other end and attach it to the 3/8 or 1\2 threads.now your
attached with one set of threads left. go to your local car wash
get the high pressure gun and hose attach that to the threaded
end now your flame thrower is complete. fill the tank with what
ever you want. the pressure is so great it will fire any
substance imaginable. remember scuba tanks come in all sizes .
you should see the vehicle mounted one I have!!!!!!
