Why does water form droplets instead of spreading out flat on glass?
What is surface tension and cohesive forces at a molecular level? how do anti-rain coatings like Rain-X change the surface energy of glass?

Water molecules prefer binding to each other rather than the silica in glass due to hydrogen bonding. Hydrophobic coatings increase this contact angle dramatically.
