A fun and intriguing demonstration of Newtonian physics. When properly arranged, a slow moving steel ball will be accelerated to 3-4 times its original speed by the pull of magnets and Newton's Third Law of Motion. The Gaussian Gun comes with 4 neodymium magnets, 4 magnet holders which allow the user to move the magnets and reverse their polarity towards one another. Ten 3/4" steel balls, and a low friction track with an open end for launching the balls. This device can be used to teach magnetism, motion, Newton's Laws, and can be used as a fun ball launcher for other experiments and demonstrations.
