Hydrophobic Sand
Hydrophobic Sand, also known as magic sand has a very interesting property when water is added.
The surface of sand grains is wetted by water, which means that water molecules are attracted to sand grains. Remember, this water-loving property of sand is called a hydrophilic property. Magic Sand is regular sand that has been coated with an oil- like substance that is water-hating or hydrophobic.
