Water vapor - what you can actually see -

Water vapor is a gas and is invisible.

You are correct, I should have said "mist". The point being that what
most people routinely think of as "steam" is not steam, but condensate.

Steam is the vapor phase of
water. Clouds are liquid water.

Yes, and clouds 'fly'. Hence the "water doesn't flow uphill" statement,
in this context doesn't...hold water.

The liquid is hundreds of times as
dense as the vapor, by the way.

Really?
