Watch the bobbing bird drink from a cool glass of water! Is it magic? Is it a robot? Is it a magic robot? It's something even better! Thermodynamics! The cool temperature of the wa ter makes the birds beak cold, which changes the pressure inside the birds body causing the liquid to fall down. As the temperature heats up again the water is pulled back up, making the birds head heavy so it dips in the water and the process starts all over again! Bobbing bird is made of glass and plastic. Approx. 7" tall. Show more
