TWILIGHT HYPERCOLOR THINKING PUTTY

Just as an evening sky melts into the dark of night, Twilight Hypercolor Thinking Putty's deep purple color disappears with a touch of heat to reveal a fluorescent blue complexion.

These Heat Sensitive Hypercolors really make their mark!  Twilight Hypercolor Thinking Putty is thermochromic - just a touch from your hands or a warm coffee mug will reveal a new "hot" color. Allow it to cool off or stick it in the fridge! Then the "cool" color will be restored.
