The classic scientific wonder!
The Drinking Bird has been a scientific novelty favorite for decades. The bird bends down to dip its beak into a glass of water over and over all by itself. While it may appear to be a perpetual motion machine, it is actually a heat engine that runs at room temperature, and provides a great physics lesson on evaporation and condensation. For more information on how the bird works, check out our blog.
