DIY Air Cannon

I made my first air cannon to demonstrate to my class how angles affect range in rockets. This has proven useful as it is a great way to demonstrate correlation in algebra. Be aware that any time high pressure air is used, there is a chance of explosion. Be sure to follow all instructions on packaging when applying pvc cement.
