Einstein's drinking duck
The most famous physics toy in the world!
In 1846, the American Miles Sullivan patented a small glass bird that continuously bobbed and dipped its beak into a glass of water. Not a few people saw the bird as the long-awaited perpetual motion machine, and so it became not only a worldwide bestseller, but also one of the most famous physical toys.
Albert Einstein had a drinking duck on his breakfast table. He was delighted by the infinite endurance with which it seemed to disprove the laws of thermodynamics. If you regularly refill its water bowl, it will forever quench its thirst with its typical bobbing movements.
