Surface Tension Explained | Cohesion & Why Water Sticks to Itself

Understanding Water - Chapter 02: What is surface tension? How are some insects able to walk on water? Why do droplets take on a spherical shape? In this second chapter of a mult-part dumentary series we delve into the enchanting world of surface tension - an invisible force that shapes water in ways both delicate and profound. This journey uncovers the intricate dance of water molecules at the surface, revealing their remarkable behavior. 🔍 Please let me know your comments and questions below, and consider subscribing to my channel to continue exploring the extraordinary forces of water that shape our world!
