Product description

This 10-piece set of 25.4mm cubes is made to test density in the classroom, and by all means you should do that. Otherwise, how will the children ever understand density? But we like to just play with the cubes, to set them on a desk, or stack them, or line them up, or make shapes out of them, or just pick them up and marvel at their weight differences. You get perfect cubes of Copper, Brass, Aluminium, Arylic, Mild steel, Nylon, PVC, softwood, wood, Hardwood
