Create Fun, Wiggly Blue Strings While You Explore Polymer Science!
You get enough materials to make about 40 ft (12 m) of String Slime!
Squeeze a long stream of Blue String Slime into the Activator Solution and you’ll get an instant gooey string. Go ahead… dip your finger into the solution and fish out the coolest rubbery string you’ve ever seen. It’s a cross-linking reaction between sodium alginate and a solution of calcium chloride that happens the moment the two liquids mix. If you love the traditional slime reaction using PVA and Borax, you’ll love this new cross-linking reaction that’s guaranteed to knock your socks off.
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 for?
This activity is suited for all ages. For the younger children, it is a great introduction to chemistry and polymers. The experiment allows them to have a very hands-on experience with science. For the older ones, the instant chemical change explores the science of cross-linking long chains of molecules.
