The Gauss Rifle also known as the Gaussian gun is a very simple experiment that uses a magnetic chain reaction to launch a steel marble at a target at high speed. This educational and amusing project is very simple to build (it only takes a few minutes), is is very simple to understand and explain, and yet fascinating to watch and to use.
The movie in the right shows a sample of the gauss rifle in action. In the beginning, a steel ball starts rolling towards a magnet taped to a plastic rail. As soon as the rolling ball hits the magnet, another ball in the opposite side is launched and leaves the device at a very high speed.
