This cool device will baffle your students as they try to explain why this top keeps on going!
Just an easy clockwise twist will set this top spinning for an unbelievable length of time. A tiny battery powered off-center motor maintains the rotational inertia of the top making it appear to continue spinning on its own. While spinning alternating red, green and blue LED lights are activated. Includes batteries for initial use and a set of spares. For additional batteries see type CR2032 in related products.
Small Parts. Not for children under 3 years.
