American Scientific Chain Reaction Magnetic Cannon

Here is another physics toy that you can use to explore the world of magnets. The American Scientific Chain Reaction Magnetic Accelerator looks like a tiny rocket. It has neodymium magnets embedded between each step. This gauss rifle unleashes a chain reaction to transfer energy as the steel balls collide.

This magnetic cannon comes with 4 wood mini-barrels and 9 steel marbles.
