Crazy Aaron's Thinking Putty, Glow in the Dark, Ion from Putty World is a handful of luminescent mind-bending fun. Plain white in daylight, once exposed to light, it glows a beautiful turquoise in the dark. Thinking Putty is proudly made in the U.S.A. by exceptional individuals with intellectual and physical disabilities.
You'll swear you can see the electrons buzzing around -- generating this icy blue glow. An extraterrestrial turquoise glows all night long. Dim the lights, zone out, and enjoy a soothing, hypnotic experience.
