  • A series of cube magnets are placed 2.5” apart from each other.
  • Two steel balls are placed to one side of each magnet
  • A lone ball is then slowly rolled toward the first magnet, coming in from the opposite side of the sphere pairs. The lone ball will strike the first magnet causing a sphere to be ejected from the opposite side.
  • This sphere rolls toward the next magnet and s on.
  • The last ball will fly off with a speed of a few metes per second. Place a soda can in front of it and see it flying.
