Exciting and mysterious
Our rebellious Rattleback Spinner is quite a phenomenal physical curiosity. It is an exciting and ancient, spinning, semi-ellipsoidal top that reverses its spinning direction. You can start spinning it in the opposite direction and it will reverse to only spin one way, seeming to violate the angular-momentum conservation law of physics.
The Rattleback is a spinning toy that reverses its spinning direction. Discovered by archaeologists investigating ancient Celtic and Egyptian sites, these are also known as wobblestones or celt stones. A fun toy that is also great for physics demonstrations in the classroom. Great gift for all ages and makes a great stocking stuffer!
