Build your own Gauss Rifle.

What could be more fun?

“The Gauss Rifle: A Magnetic Linear Accelerator

“This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch and to use.”
