Magic sand / Moon sand (hydrophobic sand)

This is normal sand coated with a hydrophobic material that repels water, so this sand will never get wet. This was originally developed to clean petroleum from sea water because the sand can mix with the oil and it sinks, instead of staying in the surface of the sea. But that sand is too expensive to produce so its used as a toy. Its used in some Artic areas too because Magic sand never frezes. This was a gift from a friend (oscar8777b in youtube). Thanks Oscar :)
