Why does water sometimes make things slipperier (e.g. hydroplaning) and other times make things “stickier” (e.g. putting socks on wet feet)?

Question

Hopefully the question is clear: basically, why is it that water on roads decreases friction, and water on a floor can make it easier to slip, but water droplets on feet make putting on socks harder?

Answer 1

It has to do with the molecular properties of water. When there is a lot of water such as on the road it reduces the friction of the 2 surfaces and makes them have less friction because there is a film of water on both objects. Water on water. But on your skin like taking off a wet t shirt. Water has a lot of friction on objects and water doesn’t sit on your skin so it’s friction against the wet t shirt.
