Known as the Mood Yo. The yo in this exhibit is one of the very first Mood Yos that came off the production line at Playmaxx. It came out in January, 1999 and was won off the Internet before they were shipped from Playmaxx for sale to the public. The colors of the yo-yos in this line were known as crayon colors.
This novelty yo-yo is self-explanatory if you had a mood ring from about the mid 1970s. With this version you pressed your thumb on the black circle for at least 10 seconds. The heat-sensitive material temporarily changed color to either blue (Yo Cool), green (So Cool), red (Lo Cool) , or no change (No Cool), indicating how "cool" you were at the moment.
