Science : Ignite Curiosity

The best way to learn science is through hands-on activity. More must-haves for young explorers.


Ages: 6 - 13 Years
Overview: Create Colorful Shapes With Chemistry! Explore the World of Polymers with Shape Gel(TM) and Show Your Artistic Ability Too! Comes with 2 Goo Colors Blue and Yellow Shape Gel(TM), and Activator Powder to create a Puffy Starfish. Time to be Amazed!
  • GET STARTED: Squeeze the two liquids into a shape to create unique polymers. All you have to do is combine colors and design your shape. Then submerge into the Activator, and Voilá! You created your first polymer shape! This is a non-borax and non-glue slime formula that is safe and easy to use! Amazing fluorescent colors won't stain your hands.
  • HOW DOES IT WORK?: Making Shape Gel is a chemical reaction that makes a new solid substance (the "star") by combining the two liquids. The scientific name for the gooey Shape Gel liquid is sodium alginate, and it's full of very l-o-n-g molecules called polymers. The Activator Solution contains calcium which links together one long polymer chain to another long polymer chain in the sodium alginate. The instant these two liquids meet, the crosslinking process begins. This means that the molecules join to create long chains of molecules and form a sort of skin on the outside of the star where first contact is made, and then works its way inward. When the molecules bond, the long chains of molecules form and they appear to tighten or harden. This is what changes the Shape Gel star as it floats out of the mold. The crosslinking process pulls from the outside in, giving more of a "puffy or ball" appearance. As the crosslinking process continues, it causes the star to change as it pulls in the tips towards its midpoint.
  • STEM: Our STEM products encourage young scientists to create new and exciting experiences that foster the skills of collaboration, communication, critical thinking, and creativity. What other toys or crafty items could you mix with Shape Gel goo to create new and different creations? Over time, Shape Gel will dry out (dehydrate) and shrink. But, a very cool thing happens to Shape Gel stars as they dry.
  • 3 EXPERIMENTS: Instruction Card included with 3 Experiments: Getting Started, Super Swirly Stars, and Puffy Starfish.
  • WHAT'S INCLUDED: Shape Gel(TM) Activator Powder 0.7 oz (20 g), Yellow, and Blue Shape Gel(TM) Goo 3.4 fl oz. (120 mL) each, 1 Plastic Star Shape Mold, and Instruction Cards.
  • SAFETY: Adult supervision recommended. Won't stain hands.
