This Heat Sensitive Hypercolors really make their mark! Thermal 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.

Each metal tin is hand packed with 1/5 lb (90 grams) of Thinking Putty.
