I think it's much easier and truthful to stop talking about temperature and introduce speed in that context.

The average speed is what we percieve as temperature, but single molecules can be fast, so fast as to break the boundaries of the liquid pool and shoot up toward space.

Single unbounded molecules are what gas is.

But temperature is not just the speed of a molecule right? Isn't it also like the "energy" stored in the molecule, or its "wiggling" or something? Like a molecule moving very fast through space can still be at a very low temperature, right?

It pretty much is.

Like a molecule moving very fast through space can still be at a very low temperature, right?

That very much depends on the relative speed of the molecule and you. If you're not moving in relation to the molecule, a collision between you and it won't do much. Now try being hit by it (or a bunch of them) at high or even relativistic speeds. The area of you that's hit will surely become pretty hot then.

Like, have you seen footage of asteroid impacts? Have you seen shooting stars? Those are hot. Like, non-figuratively.

Wait it's all models? Alwasy has been.

It's kinetic energy, temperature itself is not a real thing, you are dealing with the bonds that keep water molecules together, if you wiggle hard enought, with enough energy (so... fast enough?) you break free.

I guess another way to look at it is the cloud of elecrons getting more and more messy, so that it destabilizes the bonds...
