This amazing sand will not get wet! Pour the sand into a glass of water and mold into fun shapes under water. Remove it with a spoon and it will emerge completely dry!
Created by coating sand with a hydrophobic compound, this causes the grains of sand to adhere to one another and form cylinders to minimize surface area when exposed to water.
This sand is the closest thing to sand on Mars and is used in real life to clean ocean oil spills.
