Mysterious spinning top
Give this spinning top a spin and watch it spin for hours without stopping.
The secret revealed: the spinning top contains a small magnet. As this magnet moves past the center of the black base, the top’s magnetic field induces a current in a coil, which closes a switch, allowing a battery to instantly activate a small electromagnet. The spinning top increases its speed and spins away from the center of the base.SKU: FR-313110 -
