You’ve seen Styrofoam being used in packaging. Have you ever seen a product made out of Styrofoam? Airblocks are. And they’re amazingly light and sturdy. However, I digress. Styrofoam is probably the least impressive thing about the awesome Airblocks. These little badboys are programmable modular units that snap magnetically to each other. They come in Drone and Hovercraft making kits (that use the same parts). That’s where Styrofoam (technically Expanded PolyPropylene) comes in handy, with its unbelievably light weight and buoyancy abilities. A perfect learning tool for the code-curious child!
