Exploding pumpkin Answered

I wanna blow up a pumpkin Any suggestions???


"when in doubt C4" Jamie Hyneman

you could make a pvc bomb out of 2 1 inch diamerter end caps that screw into each otherand fill it with flash or black powder. then drill a SMALL hole in the side for the fuse. You can buy black powder at any gun store.

well, yes, BUT a pvc pipe bomb is mostly a loud firecracker and would take extrenuating circumstances to produce any lethal effect. i know that any and all DIY pyrotechnics are illegal unless you have a licence, but then it really isnt in the context of DIY.

Ive had previous experiences with pvc bombs and i have found that they can be very destructive. Maybe it was the type of pvc i used but i dropped one in an old bathtub at the bottom of a hill and there were SHARDS of plastic wedged in the tub. But we filled them full of black powder and glued the ends together.

I've had similar experiences. notice though that i was talking about using 2- 1inch pvc pipe ends that are threaded to screw into each other. the you can only fit about 1.5 tablespoons in one of those and because of the smaller surface area and blocky shrapnel produce a significantly less lethal effect with less penetrating efficiency while retaining a decent amount of power. I'm confident that this would be very effective in destroying the pumpkin yet still be relatively safe.

Ah. So two end caps threaded together your saying? We used a 2-3 inches of 1 inch pipe with caps glued on. That was pretty deadly. But i assume that something of your size would be less destructive but still enough to get the job done. Good day sir.

OK smart guy, where you going to get a pumpkin in May or June? Now that's an instructable I'd like to see!

Anyway, the others are right, liquid gasoline just burns. Trust me, I have the photos to prove it -> Burning Pumpkins 2004 :). Gasoline fumes, on the other hand, are fairly explosive but they need to be ignited in a semi-confined space (like a can).

Once, long ago, I blew up a pumpkin using a small hairspray can. Got a big bang and lots of flying shrapnel fun. We used gasoline to set the can off, clumsy and unpredictable, but it worked.

In any case, if you blow your fingers (or some such) off, you're on your own. Word to the wise - this stuff is dangerous.

You should use a hydrogen oxygen mix then you could just rig a blasting cap and fuse in it. :) Just light and run.

I am pretty sure all the gasoline will do is burn your pumpkin because it is no vaporized. What I would recommend you to do is run a hose from propane tank into your pumpkin ,and fill it with propane .As for the ignite I would use a disposable camera with two wires running from the capacitor with a switch between one of the wires ,and attaching a bit of steel wool to the end of the two wires. Anything else in my opinion would give an explosive concussion that would be to dangerous. This might also work better if the pumpkin has rotted a little.

Hollow out the whole pumpkin from below, make spark-gap from ends of two loooong strands of wire. Add tea-spoon of gasoline with a water mister (making vapour). Retire to far end of wire and connect charged capacitor to wire. The spark ignite vapour, pumpkin go bye-bye.

hydrogen oughta do it. just cut a hole in the BOTTOM, nearly fill it up (needs oxygen, dont forget)

Thanks but i dont have accses to saltpetre doe you now where to get some???

I'm using commercial fireworks. But I have seen saltpetre for sale on Ebay (for preserving meats) L

I'm advising that you take the insides out, like the link I posted May 31st L
