Thinking Putty – Twilight
Hypercolor Thinking Putty is thermochromic — just a touch from your hands will reveal a new “hot” color. Allow it to cool off or stick it in the fridge! Then the “cool” color will be restored.
Just as an evening sky melts into the dark of night, Twilight Thinking Putty’s deep purple color disappears with a touch of heat to reveal a fluorescent blue complexion. Help your students focus, relieve stress and use their imaginations with this fantastic tool!
