Spin This mysterius top on its base and watch it continue for hours upon hours without stopping. It is the ultimate desktop conversation piece. So how does it work? Well that is TOP SECRET.

The Science of Top Secret ™: The "Top Secret" consists of a spinning top with a radially oriented magnetic field and an associated base that houses a conductive coil. When the top spins past the center of the base, its changing magnetic field induces a current in the coil which momentarily opens the switch to the battery resulting in powering up the electromagnet. The electromagnet then delivers enough torque to the spinning top to allow it to speed up and spin away from the center. Since the electromagnet is only engaged when the top crosses near the center of the base, one 9 volt battery can last for over a week of continual use!
