potato cannon

[Ian W.]

I have a smallish potato cannon, combustion. Doesn't really have the right ratios, made it before I knew how to do it right.

Planning on "borrowing" a few solenoids from robotics in a few weeks to make me a pneumatic one, if I can. I know all the crazy formulas now, so I should be able to get it to work a lot better.

We have a radish cannon that is about a foot and a half long, and shoots baby carrots real nice. We also have a few 6 foot long 1.5" diameter tube 3" chamber with grill sparker cannons.

I recomend skipping potatos down a stream or across a lake.

A warning. The PVC will get very brittle when it is cold. If you keep it un heated, take it inside and warm it up before firing it at 30F. We shattered one firing it cold. I was surprised noone got hurt by shrapnel.

A friend of mine made a steel potato cannon that uses old gunpowder as the fuel.

I do not think that you should "borrow" things without asking your mentors. You should just save up to order your own solenoids. Then you could not be arrested. Muhahahahahhahah

My mentors let me borrow a couple solenoids to make and air cannon, but that project is on hold until the end of build session.
