A phenomenal physical curiosity! A semi-ellipsoidal top that spins in only one direction.
This toy seems to violate the angular-momentum conservation law of physics. It's a mind-bending physics experiment right in your own hands! With its unexpected behavior and fascinating motion, experimenting with the Rattleback will leave you feeling like a genius physicist...
Behold the mysterious RattleBack, with a property that amuses.
One way, it will spin; the other way, it refuses.
Exciting and mysterious.
