## 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.
