Build a Simple but Fun Magnetic Gauss Gun a.k.a. Magnetic Rail Gun

The 3 items you need are Cylinder Neodymium Magnets, Steel Balls and PVC Conduit for the path of the gun.

Place 2pcs of cylinder neodymium magnets with 2pcs of steel balls (9.5mm and 12.5mm dia. steel balls were used in this video) for each section, create 3 such section and place them inside the PVC conduit about 7-10cm apart with the steel balls all facing towards the target.

Gently roll a steel ball towards the neodymium magnet of the 1st section and watch the chain reaction from the force created by the pull of neodymium magnet on the steel ball.

The energy get transferred from one section to the next with the final ball “shooting” out from the PVC conduit.

Experiment with more sections, magnets and different sizes of steel balls!
