Drinking Bird


This classic toy returns to teach a new generation about the magic-like properties of science. Simply dip the Drinking Bird's beak into a glass of water, then, as long as there is water in the glass in front of it, it will keep going indefinitely, bobbing its head to "drink", coming up for air, and going back for more, due to clever thermodynamic designs. No batteries are needed, only a small amount of normal water.
