As if by magic, the little top spins and flashes across the floor. Once powered, it is permanently propelled by a battery-powered magnet. Even though it spins endlessly by itself (until the battery runs out), children still tend to start it again and again. Watching the spinning top is fascinating and hypnotic. The small size of this top is ideal for the fine motor skills of the fingers. The color and magnet make it interesting and challenging for older children as well. (9V battery not included.)
