Squeeze a long stream of blue Worm Goo into the Activator Solution and you’ll get an instant gooey worm. Go ahead… dip your finger into the solution and fish out the coolest rubbery worm 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.
You get enough materials to make about 12 meters (40 ft) of worms!
