More History

Most people expect Moon Sand to be made out of some special kind of sand, but really it is made out normal sand.  As I said in my previous entry normal sand is made of silica and that Moon Sand is coated in a chemical compound.  When the silica compounds and the other chemical compound combine they make the sand hydrophobic.

History

Technically Moon Sand, or Magic Sand wasn't created until 1980 but water repelling sand was mentioned in The Boy Mechanic Book 2 by Popular Mechanics.  This book talks about how East Indians had thought to have created water repelling sand, by mixing sand with melted wax.  The wax would surround the sand and then it would repel the water.
