Product Info

Aside from buying a soda, or perhaps performing a magic trick or two, there's not a whole lot for kids to do with coins..until now. Best of all, they also get to explor momentum and centripital force. When coins are dropped from launching ramps, the coins begin spinning tangent to the curved surface, traveling in a circular motion. As the coins spin into the well, their rotational velocity greatly increases. Use The Vortx for a bank for your loose change. Great for teaching gyroscopic motion, rotational energy, law of conservation of energy, etc. 36cm (15 inches) high.
