Hydrophobic Sand - This polymer coated sand repels water molecules and stays dry while submerged in water. This amazing sand will not get wet—dump it in a glass of water, remove it with a spoon, and it will emerge completely dry! There are plenty of fun experiments you can try with it and it's completely reusable.
The sand can be purchased in 2 sizes, 56 grams or 1 pound. The smaller size is prepackaged and is available in regular and neon. The 1 pound size is available in blue or pink.
