String Slime Starter Set

$15.99 USD

No glue, no Borax, no messy mixing and no stained hands — just pure awe and excitement. Simply mix the activator solution and squirt your favorite String Slime color into the liquid. The instant the two liquids touch, solid String Slime will form. Remove the strings from the bowl and you’re ready to play. Snap a string in half to reveal the gooey center and dip the ends back into the solution to seal it back up.

Explore the science of building polymers by cross-linking long chains of molecules with String Slime. String Slime is faster and easier to concoct than the traditional slime recipe — the reaction happens the instant the two liquids mix.

Squeeze the bottle of yellow or blue String Slime into the solution made with the activator powder, and long polymer chains appear, looking like wiggly worms in a bowl. Aspiring scientists will begin to appreciate how quickly a polymer reaction can occur. The String Slime Starter Kit comes with everything that is needed for fun experiments, including instruction cards that provide guidance for a variety of educational activities.

Suitable for ages 6+
