If you’ve never used a hand-held air cannon you’re missing out.
To operate one, pull back the rubber sheet and release. An air vortex forms inside the cannon and flies across the room. Watch this home made vortex cannon in action, shooting several fog rings across a room.
A clever toy manufacturer has put together a spiffy commercial version of the air vortex cannon called the AirZooka, pictured here.
To build your own vortex cannon using a 5 gallon bucket, you just need a few basic ingredients:
- 5 gallon bucket
- 2 sq feet of 4 mil plastic sheeting
- 1 12″ Canopy Tarp Tie
- Packing Tape
- Scotch Tape
- 1-1/8″ dowel for handle, about 6″
- 1/4″ thick scrap wood, roughly 1×2″
- 1″ #8 screw, pan head
And finally, here’s a military grade air vortex cannon. It launches air at 200kph. Don’t try shooting this one at your cat, you’re likely to blow all its hair right off.
You can watch this vortex cannon knock a “house” over on the BBC Youtube channel.
