Description More Information
 
Here is the classic amazing perpetual motion drinking bird, back in production. Simply wet the bird's head and place next to a glass filled with water. The Drinking Bird will continue to bob up and down as long as there is water in the glass. This device is as close as one can get to an actual perpetual motion machine and works by principles of thermodynamics. This product contains methylene chloride and is not suitable for young children but can make an interesting science project for older kids. Makes a great bar decoration.
