Make Colorful Wiggly Worms While You Explore Polymer Science! Amazing fluorescent colors won't stain your hands This is slime like you've never seen before. No glue, no Borax, no messy mixing-just amazing! Just 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. What does it teach?Explore the science of building polymers by cross-linking long chains of molecules. The process of making String Slime is faster and easier than the classic slime recipe and it happens the very second the two liquids mix. Truly amazing! What age is this activity best suited?This activity is great for all ages. Both String Slime liquid and the Activator Solution is safe to use as directed with adult supervision. Use String Slime as an introduction to chemical changes for young children, while older children will learn about polymer science through the process of cross-linking long chains of molecules together. You won't believe your eyes!Best of all, String Slime won’t stain your hands. It’s safe to touch, twist, twirl, and explore the science of polymers. Use Under a Black Light!Our special fluorescent colors will blow your mind under blacklight. Collect your favorite colors for the ultimate slime experience. For Teachers, Parents, Grandparents, and All-Around Science AdultsWe haven't forgotten about the new STEM and STEAM initiatives in our schools, bringing Science, Technology, Engineering, (Art), and Math together to make young scientist into real thinkers!
