Who knew that spelling and science could have such chemistry? We do, now that we have discovered Elemensus, a word construction game with a unique twist. As in Scrabble, players use letter tiles to form words on a board. But instead of the alphabet, the tiles show symbols from the periodic table of elements, and word scores are based on the atomic numbers of the elements. Before you know it, you will learn the entire periodic table through osmium + molybdenum + silicon + sulfur (OsMoSiS)!
