Rattleback Celt Stone Science Curiosity - Colors Vary

by Tedco

 

A science curiosity whose ancient and mysterious properties capture the attention of all ages. This little oddity has a natural spin bias and is a cylinder lens that magnifies vertically. Rattlebacks were discovered by archaeologists and were originally called celt stones. Rattlebacks are designed to only spin in one direction. If spun in the opposite direction, a rattleback will slow down, stop and reverse direction. How can it do that? Explanations are included. This plastic translucent rattleback also magnifies if it is laid down on the flat side. Each rattleback is blister packed. Colors vary. Your color will be chosen by us from our in stock inventory.
