Great little cubes of the stuff of our world is made of. Just fun, marvelous, and thought provoking....

14 elements of 1 cubic cm is there in a box Good for science experiments

These little cubes are an amazing learning prop to teach the relation between volume, density, mass and weight. Love it!

There are 13 cubes of almost pure metals plus a cube of Carbon, about 1 cm in each of the dimensions. Although highly educated, I have never seen nor held most of these. Surprised by the color, feel and weight of several of these. Fascinating and a great gift to anyone with curious mind. Well worth it. Includes Mo, Sb, W, Bi, and V, all metals! Niobium is also included, have you heard of it before? Cubes come in vacuum package in a disorderly layout so many symbols cannot be seen, thus you must open it. That is when exposure to air oxygen begins and will eventually tarnish many a cube. Try re-vacuuming if you can.

Excellent way to keep the elements clean.
