Rotating counterweighted globe sealed within a clear liquid filled acrylic sphere. The rotation is powered by light that shines through the semi-transparent Jupiter globe on to solar cells within the globe which drive a motor. But what does the motor push against to maintain the rotation? Believe it or not it uses magnets to push against the Earth's magnetic field like a compass needle. Wonderful physics of all kinds in the design of this clever device
The magnetic tipped top stays on the perimeter of the steel snake, but since the top has much more mass, the snake moves the most, slithering to and fro. This vintage top and snake came as a give away toy for kids flying on Western Airlines- a kinetic art toy that has been around for decades and takes advantage of Newton's 3rd law and rotational kinetic energy. ➡️ Follow the link above for info on where to get tops like this one and other amazing items featured here on Physicsfun
