video Build a Giant Air Cannon
Buld a large air cannon using 3D instructions (http://www.engineering.com/Videos/SomeAssemblyRequiredChannel/VideoId/2708/Build-A-Giant-Air-Cannon.aspx) and a video!

Torben generates a remarkable long-distance blast with this giant air cannon. See how to build your own in this high-energy episode of Some Assembly Required
