Drinking Bird Original : Scientific Toy The Original Drinking Bird has been a scientific novelty favorite for decades. Our amazing drinking bird bobs his blue top hat and red beak into a glass water again and again. When the funny bird gets going, he appears to be a perpetual motion machine, but actually it is an example of an evaporation heat engine. The colorful gift box includes an illustrated scientific description of the Amazing Bird. A neat Science Experiment and especially fun gift.First
