  • I added a couple of Thinking Putty tins to my last-minute Christmas order, and I couldn't be happier that I did. My children have found so many ways to be creatively entertained by it, and the adults are enjoying it just as much. Thanks! :)

  • Amazing stuff. I find myself playing along with my kids. Have mixed a little glow-in-the-dark with the chamellion and amethyst and WOW! Extremely addictive for fidgety hands. Highly recommend!

      Amethyst Purple Thinking Putty

      This amazing heat-sensitive, color-changing putty seems to defy the laws of science! Thinking Putty 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 violet to bright pink 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) 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:

      • Try "spray painting" it! First, stretch out the putty into a square or rectangle, then use a blowdryer on low power to make it purple. Next, use canned air in a pressurized canister (like what you use to clean your desk or office with) to paint a pink design onto the putty.
      • Try breaking your Thinking Putty into tiny pieces by smashing it with a hammer. Since this is a project that needs to be done outside, your putty will most likely get dirty. So take just about 1.5 oz (or half of the container) and roll it into a ball. Place the ball on the sidewalk. Wearing safety goggles to protect your eyes, hit the ball of putty with a hammer or mallet. If you hit hard enough, the ball will break almost like a piece of ceramic, and tiny pieces will go everywhere!
      • Make loud popping noises. Squish the Thinking Putty in your hands for a while, to get the air out. Then stretch it out in a rectangle, getting it as thin as possible without making a hole. Quickly fold it in half, then in half the other way. Keep folding the shrinking sheet of putty until it won't fold in half again. Squeeze the putty between your hands. As the air trapped in the putty is released, it will make lots of noise.
