Introduction: Shockwave Air Cannon

Picture of Shockwave Air Cannon

With an old shower curtain or thick trash bag, a bicycle inner tube, and a plastic bucket, you can make your own air cannon for shooting air-missiles. You can blow out candles from across a room! Great for birthday parties where you don't want the birthday kid to spit on the cake!

Way cool! My son will love the idea of making several for his friends.

Very cool and easy Instructable. Love the approach with cartoon. You rock ! P.S. This is an other possibility for the making : P.P.S Sorry for the picture quality and my english

combot55 (author)elyseDIY2008-05-07

you know the cartoons arnt his theyre howtoons's

Momghoti (author)combot552011-06-01

Er, since the Howtoon is being posted by Howtoons, I'd guess that Howtoons is posting this to generate interest in their work. Since it's apparently posted by the author/ authors company, there is no copyright issue. Please be a bit more careful before slinging arrows. If you are concerned contact Instructables instead of wildly throwing accusations.

Bhakto (author)combot552008-09-09

pluish (author)2006-08-02

you guys know some kind of rig to make it real powerfull?

Gamer917 (author)pluish2009-08-04

use a 55 gallon drum that is sealed at both ends, cut a hole in the bottom, light a small firework, throw it in, and wait for it to explode.

iraqniphobia (author)pluish2007-10-11

Same concept, except use a large trash can. Now instead of beating the plastic, attach a sub woofer. I don't know how well that'd work, but it might make a great instructable!

Larger diameter diaphragm, stronger force on the diaphragm (stronger diaphragm if it breaks). Also a smaller muzzle hole would probably give you higher velocity.

static (author)n0ukf2007-07-06

How about using a tube from a large tractor or truck tire. Put a finger pull in the center, so you can pull the diaphragm back and release it. The toy as it is, works because tapping the diaphragm decreases the volume slightly. Pulling the diaphragm back would increase the volume slightly along with decreasing the volume as it rebounds past it's neutral position into the can. Just a thought.

I have something like this but its called an airazooka

Maxaxle (author)2007-08-03

Reminds me of the AirZooka! I can't wait to build that...except that I'll use tie-wraps or something instead of a bike innertube.

jerielng (author)2007-02-23

i have something exactly like this, but it's a toy. but it's not a cannon. it's just a gun.

n0ukf (author)jerielng2007-06-06

Yeah, I had one over 30 years ago. Wham-O Air Blaster

eep! (author)2006-11-27


Not a huge genius (author)2006-10-01

guitarplayer128 (author)2006-07-13

this is sweet

splat (author)2006-07-04

I've made a smaller less powerful version of this with a plastic bottle and a ballon.

power (author)2006-06-06

when i found out what to do with this cannon i build several once and play with my friends.they blasted air around the garden.and i lose the game

power (author)2006-06-06

this look simmilar to a toy name airzooka

bricoleur (author)2006-06-01

A plastic pail is much easier than the metal cans we used to use, but the same effect can be had with no work at all now. Just pick an empty soft-sided plastic bottle and whack the side while pointing at your target. Gallon jugs are good, but the best I've found was an oversized mouthwash bottle. For better control, you can add a handle and a drumstick to wack it with.

Needs a handle, or the illustration should show him with the bucket at his hip, like a bongo drum.

Loved the Monkees doing 'Porpoise Song' on the watercannon vid. My kids' birthday's are coming-- they may need aircannons ASAP!
