How Children Play with It
Children pour water into the cube, then the hemisphere and cuboid: which one fills to the brim? Or does it spill over? Sand gets weighed, small marbles counted. The transparent walls show every bit of content straightaway, making the concept of volume tangible. Geometry shifts from abstract idea to hands-on experience. A first step into experimenting with mathematical relationships.
