This non-toxic hydrophobic sand can be moulded and formed into shapes underwater; and then lifted out to be used again and again.
This amazing sand will not get wet: dump it into a glass of water; remove it with a spoon; and it will emerge completely dry!
This sand is actually the closest thing to sand on Mars; and it is used in NASA Mars Exploration Classroom experiments.
