  • Almost everyone remembers this hard to find toy with at least a twinge of nostalgia.
  • the Drinking Bird is back, disguised as a great demonstration of thermo dynamics. When the head of the bird is moistened with water it will repeatedly tip over and appear to be drinking from a cup placed in front of it
  • The dunking is due to the evaporating water, which cools the head reducing the pressure of the gas inside.
  • The liquid inside the bird rises up from his tail towards his head, causing the bird to tip and appear to be drinking.
  • In essence this is a small , cleverly designed thermodynamic engine which only needs water to run!Size: 7 inches Age 8+
