If you have a kid who loves everything about space and planets, this Orbit Planet Clock that tells time by having tiny planets that orbit around a central “sun” makes a great gift. Watching the planets slowly revolving around in an orbit seemingly on their own is certainly mesmerizing.
The Orbit Planet Clock has 3 colored metal planets that sit in grooves on the face of the clock that represent planetary orbits around a sphere that represents the sun. The inner most planet represents the hour, the middle planet represents the minutes while the outer most planet represents the seconds. The clock comes with two larger red and blue ball bearings and a tiny shiny planet. You can use whichever metal planet you like to represent the 3 hands of the clock.
A flip to the back of the clock reveals the secret behind the self revolving planets. Instead of gravitational pull of the sun, the Orbit Planet Clock has revolving magnets that drag the metal planets around their orbits. Differences forces at work here but nonetheless just as cool.
