Kossover, Zeke in Demos, vacuum cannon
Lots of sites explain how to put them together. I like Sam Sampere's construction plan, but I use BYU's method of sealing the ends with Mylar.
This article from California State Chico does a great job of explaining the physics of the cannon.
More on figuring out the speed.
