Now Crazy Aaron's super stretchy "thinking" putty comes in excitingly eerie glow-in-the-dark form. Milky white in daylight, Krypton Putty's neon-green glow magically appears when the lights dim. After exposure to light (the brighter, the better), Krypton will glow an alien, radioactive green color for hours. 1/5 lb. of putty is ten times the fun of regular putty (and that's fun!). Made in the USA.
