Polymer Science Experiment Kit
Explore the Science of Building Polymers by Cross-Linking Long Chains of Molecules
This slime powder is like nothing you’ve ever seen before. 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.
What does String Slime Teach?
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.
What Age is This Activity Best Suited For?
This activity is great for all ages. The String Slime liquid and the activator powder are safe to use as directed, with adult supervision, of course. Use String Slime as a way to introduce future scientists to chemical changes and polymer science through the process of cross-linking long chains of molecules together.
Learn About Chemical Changes While Having Fun
Young students and future chemists can have a blast with the String Slime™ Starter Kit from Steve Spangler Science. This fun experiment shows children ages six and up the wonders of polymer chain cross-linking with the fun of fluorescent colors. When they squeeze the bottle of yellow or blue String Slime™ into the solution they make with the activator powder, long polymer chains appear, looking like wiggly worms in a bowl. Your aspiring scientists will begin to appreciate how quickly a polymer reaction can occur, and the gears in their minds will begin to turn as they start to imagine the many possible applications of what they’ve learned. 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.
