An English father of 2 children wanted to wean his children off video games & try & get them interested in Science & the Periodic table of elements, & the different forms they come in. But to collect the raw elements would become messy & could be dangerous. They could always collect the cubes, & although nice for display, they are only showing one medium, & can be expensive to collect. What if they could hold, view, collect & display different forms of different elements in a safe, neat, inexpensive & cool way? & now 15 months later, we are proud to present 3 sizes of Acrylic airtight Tiles. 12 different Mediums like natural, foil, pellets, ingots, powder, wire, grains etc.. Over 80 elements & adding more all the time. & each & every element tile is hand Created with a minimum of 2 Vinyls on each one. Also each & every tile will be unique with either different size pieces or different weight. Pure Helium Gas Ampoule Element Sample Low Pressure in Labeled Glass Bottle
