The Original Drinking Bird has been a scientific novelty favorite for decades. Our little bird bobs his red beak into a glass of water again and again. When the funny bird is in motion, he appears to be in a perpetual motion machine, but it is actually an example of evaporation heat engine in our physics lesson.
First dunk the bird’s blue top hat and red head in a glass of water. Watch the magic liquid quickly rise into his head. Then, he tips over and takes another drink, like clockwork. Buy some drinks for him today! This favorite toy from the 1960’s is back!
