When you were a kid you could get magical goo that, with a straw, allowed you blow your own plastic balloons - almost any size or any shape! They're back, but now without that horrible smell! This safe, non-toxic polymer (chiefly polyvinyl alcohol, a water soluble plastic) is great for demonstrating the characteristics of plastics and polymers. If the walls of your plastic balloon are thin enough, you can even levitate it using a FunFlyStick! Contains 12 - 5.6g tubes, each with a straw.
