ELI5: How does water evaporate, such as in puddles, when its clearly not being heated to 100 degrees?

If 100 degrees is boiling point, why can I leave a glass of water by my window and it will eventually evaporate?

200 Students in a class.
Smart students who finish their work get to go to lunchtime, where there are donuts and toys. Normally, students finish one at a time, smartest first then not-so-smart, over the course of the day.

If every student now has a private tutor that helps them, they all finish much much quicker, and everybody gets to go to lunch for donuts and toys much sooner.

For a water particle to turn into gas water, it needs energy. Heat is a type of energy. Energy isn't split evenly among the water, like how smart students are, so some get enough energy to evaporate and leave, while others don't get to leave so soon. Lots and lots of energy, then the majority now has enough energy and everybody gets to leave.

I want a donut.
