Hydrophobic sand is a type of sand that repels water. It is often used in construction and other applications where it is important to keep water out. However, there are times when it is necessary to get hydrophobic sand wet. For example, if you are trying to build a sandcastle, you will need to get the sand wet so that it will stick together.
There are several ways to get hydrophobic sand wet. One way is to use a surfactant. Surfactants are chemicals that reduce the surface tension of water, making it easier for water to penetrate the sand. Another way to get hydrophobic sand wet is to use a wetting agent. Wetting agents are chemicals that help water to spread out and penetrate the sand. There are several different types of wetting agents available, so it is important to choose one that is compatible with the type of sand you are using.
