## Description

Steve Spangler Science String Slime Deluxe Kit 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 this science experiment for kids 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! This STEM activity is great for all ages. Both String Slime liquid and the Activator powder 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. Our special fluorescent colors will blow your mind under blacklight. Collect your favorite colors for the ultimate slime experience.
