TOP SECRET


Spin this unique top on its base and watch it continue for hours, sometimes days, without stopping.

The ultimate desktop conversation piece. Perfect for executives, students, inventors, bankers, teachers, magicians, doctors, politicians, scientists...practically everyone!

Top Secret will cause onlookers to wonder if this is indeed the science of perpetual motions.

Seeing the silver top spin continuously on the enigmatic base is nearly as fun as watching your friends try to figure out why the top isn't stopping!

So how does this work, anyway? That's Top Secret!

Measures: 3.75"L x 3.75"W x 1.5"H

For aged 5 and above.



Oops...the secret is out...

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 centre 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 toe allow it to speed up and spin away from the centre. 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!
