Why do the swimmers in the Olympics splash water on them before diving in the pool? Is it for good luck?
That's because they want to maximize every opportunity they have to reduce friction. Wet skin has less friction than dry skin. that's the type of thing that gives you an advantage of 7 hundredth of a second, and that's all you need.
Maybe so that they're used to how cold the water is :)
No I'm pretty sure not for good luck. Probably because like the above^ answer said:)
Maybe it loosens them up
