Running on water

[AngelLestat]

ok.. but the context is far away from a chemical talk, in fact chemists usually said h2o instead water.
I remember that my chemistry teachers  always mention h2o.

Ice = water. There's no arguing with that.

[YNM]

The OP certainly knew which state of water is it. I mean, if the phase is let to be random, then you can't even float in water... vapor...

[Green Baron]

A human body, lungs empty and no onions eaten, is slightly denser than (pure) water .... so, in certain limits, one can control the uplift. Assuming liquid water, limited onion supply and some sort of gravity that keeps things together ...

... you could most probably not walk on it (if it's not ice) but it'll take longer to sink in and a larger partwould stick out in low gravity.

Actually, no.  Exactly the same fraction would stick out, regardless of gravity.  All that matters is the relative densities.  (Lower gravity means you weigh less... but so does the water.)

[Green Baron]

Of course, you're right. Silly me ...

Actually chemist use dH20 or ddH20 to signify the level of purification.

You can kept searching..  in all the definitions is refers to the liquid form of h2o.
The fact that you can get water if you melt ice is not the same than said ice=water.

@YNM Vapor (no steam) is still liquid water, but in your example case is the same.

I never hear about it..  but I am not a chemist, I just had the required courses only because my career had the "engineering" word in it.

Why so many post about almost anything in internet ends discussing about semantics?

[sevenperforce]

Geez, semantic arguments? Really?

It's obvious what the OP meant, so anyone talking about ice is just joking. No need to challenge or dissect it. 

Besides, while "water" is typically used to refer to a liquid state in lay conversation, any discussion in the context of science, engineering, or space is going to permit the use of "water" to refer to all three phases. "Ice" is not restricted to water ice in scientific circles.
