Thinking Putty - Thermodynamic (Heat Sensitive) Hypercolor, by Crazy Aaron's Putty World

Learn about 

These heat-sensitive Hypercolors really make their mark!  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. 

You can even do tricks with Hypercolor Thinking Putty! It stretches like rubber, bounces like a ball, tears like paper, and can shatter like ceramic.  Stressed at work?  Have a creative block?  Just whip out some putty, clear your mind, and let the creativity flow!

Unlike it's cheeper competitors, Thinking Putty is in a class of its own - with its own unique physical properties and amazing colors! Thinking Putty doesn't leave a sticky residue on your hands and you won't feel the need to "wash up" after playing with this awesome creation.

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


  • Twilight (deep purple  heats to fluorescent blue)
  • Chameleon (green heats to fluorescent yellow)
  • Amethyst Blush (violet heats to fluorescent pink)
  • Sunburst (orange heats to yellow)

Geek Alert!

Thermodynamics is the area of physicas that explores the relationships and conversions between heat and other forms of energy!
