This is a short video demonstration of magic sand.
Magic sand is a special type of hydrophobic sand. It can be blue or red in colour.
Due to its water repellence, grains of the sand will adhere to each other in the presence of water. When sprinkling grains onto the surface of water, they will at first form a “sand raft,” until the weight of the agglomerate is large enough to break the surface tension. The mass will then sink to the bottom as a single object. When immersed, the sand forms columns in order to reduce the surface area in contact with water. As soon as the sand is taken out of water, it is completely dry and flows freely.
