Polymer Power

Polymers are flexible, pliable and stretchy. Diving into the world of polymers is super fun with gooey string slime. Kids explore the science of building polymers. The fun and learning will be free flowing as they color, create and interact with cross-linked and tangled string slime polymers.

Glowing Colors

Mix-up the Activator solution and squirt your favorite String Slime color into the liquid. The instant the two liquids touch, you get solid String Slime. Remove the strings from the bowl and you're ready to play. Snap the string in half to reveal the gooey center. Just dip the ends into the Activator solution to seal it back up. Check out our fluorescent colors under a black light. Their glowing colorfulness is really amazing.

Science : Ignite Curiosity

The best way to learn science is through hands-on activity. More must-haves for young explorers.
