INSTA-WORMS
Insta-Worms™ work very well in demonstrating the science of polymers as they are primarily made out of a liquid called sodium alginate. Sodium Alginate, (a.k.a. Worm Goo by the scientists at Steve and Spangler Science), is a long chain of large molecules, which are polymers taken from seaweed, it is also commonly used as a thickener in some foods such as ice cream and even for dental impression materials.
