Drinking birds are toy heat engines that mimic the motions of a bird drinking from a fountain or other water source. They are also known as bobble, happy, dippy, dipping, drinking bobble birdie, tippy, tipping, Mr. dippy, sippy, sippy tippy, sipping, sippy-dip, dip-dip, dinking, dinky-dinky, or dunking birds. It is sometimes incorrectly considered a perpetual motion device.
