built a Bored cannon was impressed
I was sitting at home bored and after a quick trip to wal-mart and 12 dollars later I had an interesting new pneumatic cannon. I used 3/4" SCH 40 pipe with a ball valve for the chamber (small I know). I actually found a aluminum sprinkler that was pressure rated that extends out or is removable. Its difficult to describe when I am able to I will post a picture. The larger tube is perfect size for a AA battery and at only 30 PSI was destructive. The inner extendable tube is somewhat smaller and I think may be perfect for AAA if I can find any. I did test it up to 70 PSI with wadding and a vitamin and did get to see a Vitamin atomized against a Concrete wall. Once its daylight tomorrow after work I will go test it a little and get some pictures up.
