This amazing heat-sensitive, color-changing Thinking Putty seems to defy the laws of science! This cool toy is a non-Newtonian substance that can act as both a solid and a liquid. Push it gently with your finger, and it feels slimy; push it hard with your palm, and it feels tough. It can bounce like a rubber ball, or smash like ceramic if you hit it on the sidewalk.
The color of this cool putty changes from deep green to lime green to greenish yellow with temperature change. Provides hours of entertainment-and stress-relief!-as well as an example of unique characteristics of non-Newtonian substances. You'll get 1/5 lb (3.2 oz-a generous handful) of putty in a metal tin, and it won't dry out.
This product is non-toxic and is safe for those with latex allergies. Made in the USA.
Ideas for using Thinking Putty:
