Mood rings were invented in 1967 by a man named Marvin Wernick, who saw a great idea for a toy when he saw one of his friends take a child's temperature by using a strip of thermotropic material. A mood ring is essentially a liquid thermometer that changes color according to the temperature on the wearer's skin. It is thought that this may indicate the mood of the wearer, as some claim that body heat fluctuates with the emotional state of the wearer. This is no ordinary mood ring, however--it features a cool flame effect when changing colors. Highly recommended when trying to find out what your loved one is really feeling--or if you need a small but neat stocking stuffer, gag gift or novelty toy!
