How was the Periodic Element guy born? 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? And now 15 months later, we are proud to present 2 sizes of Acrylic airtight Tiles, the small for the whole family and the big ones for adults. 12different series in most forms of medium, like natural, foil, pellets, ingot, powderetc. Over 60 elements and adding more all the time.
