An English father of 2 children wanted to wean his children off video games and try and get them interestedin Science and the Periodic table of elements, and the different forms theycome in. But to collect the raw elements would become messy and could bedangerous. They could always collect the cubes, and although nice for display, they are only showing one medium, and can be expensive to collect.What if they could hold, view and collect different forms ofdifferent elements in a safe, neat, inexpensive and cool way?
