Your Thumbler turns off as soon as you stop gyrating the shell.

In scientific terminology, as the top spins, its axle is said to precess around the vertical direction. The earth’s axis exhibits a similar motion called “the precession of the equinoxes”, completing one cycle every 26,000 years, and is partly responsible for the cold periods we call ice ages! With skill, your Thumbler can be made to spin more than 25 times per second, while the axle precesses only a few times per second!

Tumbler strengthens fingers, wrists, hands, and forearms, and can help to increase blood circulation.
