Like rain on the bottom of a car door handle
In: Physics
Water in general forms strong intermolecular forces called hydrogen bonds. Water droplets like on the underside of a door handle have a side exposed to air and so the molecules form stronger bonds within the droplet as there are less molecules to bond with surrounding it. This results in a cohesive property. Since droplets are very light, on this scale these bonds are sometimes stronger than the force of gravity, allowing it to grip the bottom of the handle.
edit: cohesive property causes the droplet’s spherical shape, adhesive property causes it to stick to surfaces. Both are a result of the intermolecular forces
Capillary action. Basically the wetness that originally starts somewhere kind of acts like a base then as more water goes there it sticks to the initial water allowing for it to “grip”
