How to Build Your Own T Shirt Air Cannon
T-Shirt Air Cannons are frequently seen at sports events and are used as an easy and fun way to distribute t-shirts among large crowds. The principles behind the air cannon aren't difficult, essentially the air cannon is two tubes that are connected by a valve. One tube contains pressurized air and another your t-shirt to be launched. Releasing the valve between the tubes releases the pressurized air, which catches the t-shirt and sends it flying through the air. While the principles are easy enough the build itself will require forethought and care.
