Shifts colors right before your eyes! Crazy Aaron's Thinking Putty- Super Illusions from Puttyworld is a handful of iridescent, mind-bending fun. An oil slick, a lava pit, insect anatomy, and this amazing putty all have a thin-film interference effect in common, caused by light waves that are reflected and refracted by a veiled or structurally complex coating -- cool!
Thinking Putty is proudly made in the U.S.A. and employs exceptional individuals with intellectual and physical disabilities.
