Hypercolors: These are the heat-sensitive putties that change color before your eyes; they never cease to amaze.
Thinking Putty Chameleon Hypercolor is thermochromic – meaning just a touch from your hands or a warm coffee mug will reveal a new “hot” colour. Allow it to cool off or stick it in the fridge! Then the “cool” colour will be restored.
Twilight – “Invisible in the jungle but sure to stand out in your hands, Chameleon Thinking Putty’s lush, tropical green explodes into a bright fluorescent yellow with just a touch of heat. And, unlike the real thing, all this Chameleon needs is a daily squeezing!”
