Mengers Sponge

A what?!? A Menger’s Sponge is a cubical mathematical figure that can be added to indefinitely if you have the room, time and patience. Doug will show you how to connect business cards into a cube and then connect the cubes to each other. The faces of the cubes can be paneled for a smoother, finished look. Jeannine Mosely, the creator of this model, made one that was several feet high. Folding is super simple, assembly is somewhat trickier.
