Clear Insta-Worm Kit

Product Videos

Squeeze a long stream of Worm Goo into the Activator Solution and you'll get Instant Worms! You won't believe your eyes as the honey-like "Worm Goo" changes into a rubbery solid the second the two solutions mix. This unique polymer formulation (no Borax or PVA used here) is safe to touch and weave between your fingers. The "hands-on science" factor is great for younger students, while the strong content makes the activity perfect for upper-level students and teachers. If you love the classic "slime" activity, Insta-Worms is guaranteed to knock your socks off! You get enough materials to make about 12 meters (40 ft) of Worms!

What's Included?
  • 240 mL of Clear Worm Goo
  • 12 g of calcium chloride
  • In-depth activity guide
What Does It Teach?

Explore the science of building polymers by cross-linking long chains of molecules. The process of making Instant Worms is faster and easier than the classic Slime recipe and it happens the very second the two liquids mix. Truly amazing!

nice product Review by chemistry

Fun to play with. I love that it isn't slimy when you pull it from the activator, but it is just cool and has a thin film out the outside. (Posted on 4/18/14)
