It isn't possible for the flame to back up into the gun and explode, well, to a point. For soemthing, anything, to burn it must have air, without it nothing happens. In a water gun the line running from the nozzle to the tank is competly filled with liquid. There is no room for air, therefore no possibility for fire. However as you begin to run out of liquid and the tank sucks dry you get a fuel air mix coming out of the nozzle, then if you aren't careful an explosion is technically possible.

I dug up that link on hackaday a while back it's a pretty stable design. There's also a water proof camera case on hackaday somewhere if you want to look it up. I think the underwater camera case costs about $30 to make. I'm not sure about the flamethrower though. You can find some seriously cool things to make at hackaday.com.

A friend of mine made something like that guy, but unfortunately the pilot light broke and died after 1 second of firing, so all we had was a pressurised spray of unlit flammable liquid. And it started leaking then, so it had to be scrapped. It was pretty funny actually, we were all killing ourselves with anticipation to see the thing go off (he spent like a month working on it) then just as we thought it had worked the whole thing petered out.XhuntedoverlordX wrote:http://carpetmonster.pwp.blueyonder.co.uk/fj.htm

yeh gasoline/ petrol does dissolve plastic, i didn't realise until the plastic was going 'gooey' in my hands, does anyone no why this happens, this there a cheap protective layer you can buy, some sort of cheap chemical substance, there must be something out there?

Yeah, because plastics are made from petrochemicals they bond to each other and become a thick liquid. Plastic jerry cans are treated on the inside with a special process (I think it may be a very thin layer of glass, or an non-PVC epoxy). As far as a coating you can apply yourself; no, I'm not aware of anything that exists.

I can tell you a safe (relatively) way to get a flame thrower that you can use for extended periods of time is made from a propane tank. Take the propane tank and mount it to a belt or whatever you want to hold it to someone. Then unscrew the tip of the torch so you have an exposed thread end of the nozle. At this point is where I got creative, take some clear water tubing, and make it whatever length you want, then get a piece of copper tubing about 6-8 inches in length and push it in the end of the tube, make sure its very very tight so it doesn't leak. I actually bought one size up, and heated the tubing with a hairdryer so it would stretch, and forced it in the end, then when it cools, that baby ain't coming back out. Next bend the tip of the copper over and mash it pretty flat so you seal the end of it. Then take a small drill bit and make a little hole at the end, turn on the gas and light it. It will throw a stream of fire about 6-8 feet and looks awesome.
Have fun, if you would like a tut, I can through something together and get it up over the weekend. Cost is about $20 total, cheaper if you own the propane tourch already.

I dont know if someone posted this, because i didnt look through all the replies. But, what i did was this.
I took a can of spray deoderant and a clothes hangar. I gun the hanger with bolt cutters and taped one end to the deoderant can. the other end went in front of the can. I bent that end upward and taped a candle on it.
Now, all you have to do is light the candle and spray the deoderant.
***I recommend RightGuard because the way the can is designed. The thing you click is horizontal, so when you hold it, it shoots out the way you want it***(i dont know if that just made sense, maybe i wrote it in a bad way)
