Heat Sensitive

These Heat Sensitive Hypercolors really make their mark!

Hypercolor Crazy Aaron's 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. You can even do tricks with Hypercolor Thinking Putty!

Made in the USA!

Each 4" metal tin is hand packed with 1/5 lb of Thinking Putty, much more than you get in a plastic egg!
