Hydrophobic surface is a surface that has the ability to repel water. Generally, the hydrophobicity of a surface can be measured by the contact angle between the droplets of water with the surface itself. The water droplets on the hydrophobic surface will flow very easily and retain its spherical shape with contact angle more than 90 degrees, while superhydrophobic materials possess large contact angles above 150 degrees and difficult to wet. -------------------------------- How to get your comp

DIY Hydrophobic Sand: Create Water-Repellent Magic at Home! #Chemistry #ScienceatHome Hydrophobic sand is a type of sand that has been coated with a hydrophobic substance, making it water-repellent. This means that when the sand comes into contact with water, it does not get wet and instead forms clumps that stay dry. This unique property creates fascinating visual effects and has practical applications in areas like construction, art, and environmental cleanup. | Chemical Kim
