Stretch, tear, and even smash it! Thinking Putty is an incredibly fun toy, a great stress-reliever, and it's also educational, demonstrating the properties of a non-Newtonian substance. The color-changing Thinking Putty changes color with temperature changes, while the Strange Attractor putty has cool magnetic properties, and the Ion putty glows in the dark and can even create triboluminescent light. Thinking Putty makes a cool stocking stuffer or inexpensive gift for any occasion. It's non-toxic and great for ages 7 & up. Made in USA. Collect all the colors!
My 14 and 12 year olds love this stuff. The color changing effect is great and you should see some of the 'monster' effects my son has created...–Terri
