You gave me an Idea. It would be hard but imagine, taking a card board box and filling it with newspaper. Light it on fire and throw a oil or kerosene filled water balloon an watch it catch aflame!

[-insertnamehere-]

Now you have given me an idea..... what happens when you light a paper airplane on fire?

[Millawi Legend]

I did that once. I drenched it in lighter fluid and threw it and it was a mini 9/11.

[kibbler]

[Millawi Legend]

And when you think about the 100,000 estimated civilians dead in Iraq using the knee-jerk reaction of this as a cover, you'd realise that's nothing more than a drop in a bucket.

Kerosene or gas will quickly eat the latex of the balloon. However, you can fill a balloon with butane (found with cigarette lighters). Any flame -- a match, a small torch -- will cause the balloon to explode. We did this in the circus as part of our fire-eating act: clown wandered in between fire-eaters with butane-filled balloon, fire eater placed lit torch under balloon for big bang and fiery burst. Best done outdoors or in a room with plenty of ventilation (gymnasium).

instead of shooting clay pigeons, shoot kerosene soaked tennis balls, PULL!!!

[thedog458]

don't use kero for flame thrower its way to flammable use mineral trerps or metholated spirits.=) grate Instructable

[hcold]

Methylated spirits has a was lower flashpoint that kerosene, which is what I assume you mean. Kerosene has to be "vapourised" before it will burn readily, like dropping a match into a tank of gas.

[JerBear]

won't dropping a match into a tank of gasoline just put out the match?

[thedog458]

yer that what I meant but I was way tired when I write it lol =)

[struckbyanarrow]

[burnoutxd]

i like the concept of such a simple everyday device becoming a new exciting toy! well done

[Wetwillie1800]

But Seriously, Could you imagine? Toss one of these onto someone elses tennis match for an exciting surprise!

[-insertnamehere-]

If you wanted it to spray on contact, I suggest you make the hole bigger...with the small hole, it self seals itself.

[Wetwillie1800]

Wow... Fascinating... (Insert Awkward Silence Here)O.o
