Extreme Marshmallow Cannon

Extreme Marshmallow Cannon
This is a air pressurized cannon. Pumped by a bike pump, air released by a electric sprinkler valve. The PVC tubes are changeable for what you want to shoot. I shoot marshmallows, apples slices and t-shirts. The longest distance I've gotten is 180 feet. All depends on how much air you pump into it. So FUN!!!

If you want it to go farther you need more pressure. If your confident that you primed/glued your joints well then you can easily crank that up to 120psi (get an air compressor and put that bike pump away). You will also need denser projectiles. Potatoes work well, so do apples. If your trying to huck a potato you might want to invest in a rifled barrel (you can get those online).

If it says there's to much space in the video then you can become a pro member and the video will work but that's up to you.

It's hard, but that's more likely to get votes than just pictures. :P I would love to see the instructions, as I want to make one.

This sounds awesome. I agree with Kaptain Kool, tell us how you made it and post a video! I would love to see it in action.
