Surfer & Shark - Kinetic Balance Toy

Balance can be tricky sometimes!

Explore the beauty of physics with this funny kinetic balance toy :)

But how does it work? How can the heavy shark and the small surfer guy be perfectly balanced? How can they move around, swinging up and down, without falling from the coral reef base?

Well, the answer is Physics!

The shark is heavy but very close to the center of rotation, while the surfer guy is very light and far away from the center. In this way the torque is the same and they are in perfect equilibrium.
