Universal Specialties Magic Drinking Trex Tyrannosaurus Rex Dinosaur Desk Toy

An Innovative twist to the Original Drinking Bird, the scientific novelty that has been around since the 1960's! The Trex bobs his head into a glass of water over and over without continuous stimulation. When the Tyrannosaurus Rex is in motion, he mimics a perpetual motion machine, but he is actually just a simple example of an evaporation heat engine. About 8 Inches tall. Please note this product is not intended for use by children under age of 8. Inside the glass tube is methylene chloride which may stain clothing and other surfaces if broken. Do not swallow liquid or allow to come in contact with the eyes or skin.
