A fun curiosity, this Rattleback (known as a celt in ancient times) demonstrates Newton's Laws of Motion! You can experience what having a preferred direction of rotation leads to.
The translucent Rattleback can also manify when placed flat side down. See what happens when you magnify a newspaper or a TV screen!
Available in red, orange, green, and blue. Colors will vary depending on store's availability.
