Educational Innovations is very excited to offer these new, beautiful Styrofoam pellets for experimentation. No, we didn't corner the market on bean bag chairs. In fact, we've dissected our last bean bag chair. These pellets are extremely clean and smooth and the insulating qualities make them perfect for all kinds of static electricity experiments such as our Static Tube Experiment Kit (Item SS-7). The pellets move so easily over each other, a container full pours nearly as easily as a liquid. They can even be used to model the physical differences between solids, liquids, and gases.
