Take Silly Putty to the next level! Synthesized in 1943 at DOW Corning as a possible substitute for natural rubber, it has remained a popular "toy". Sold as "Silly Putty™" and "Thinking Putty." Over the years, it remains one of the most interesting materials to study. It bounces like a super ball, it flows slowly like slime, shears when quickly pulled and lifts ink off printed matter. Threads of it are attracted to a static charge. But wait...there's more... using a heat-sensitive dye, these silicone balls will change color with the heat of your hand, and even from the heat generated from pulling and stretching. For ages 8 and up.
