Product Description
Give the disk a spin on the concave mirrored surface and it will keep spinning and rolling like a coin . . . a coin that doesn’t seem like it will ever stop.
An impressive demonstration on the conservation of energy and angular momentum with a constant change in sound pitch and speed. Amazing to use in a darkened room with flashlight or low powered laser as it comes with holographic magnetised disks and wedges. Very easy to operate. NO batteries required - physics will do it. A great gift and irresistible desk toy!
