I like pie.

Hair, poontang, or cherry?

I Did that thing once At Norway Mountian in da UP eh....

When you hit the water at like 60mph its kinda easy to make it all the way accross

"If the water is very clean and is not agitated or disturbed it can cool well below the normal freezing point without freezing."

The water in the picture does appear to have been disturbed (again with the skiers and snowboarders) and does not look very clean (clean = free of contaminates). Therefore the water could be below 32F and still in a liquid state.

These two statements appear to be a contradiction.

My original smart azz comment was and is that I think the OP over or under(depending on how you look at it) estimate the water temperature. Even sea water(salt water) freezes at more then 10F(22F I think, it depending on the salt content) not to mention water that cold(if you could get it that cold without freezing) is deadly.

First off I'd like to say that my initial comment was a blatant misreading of what was initially said. I read that the temperature outside was 10 degrees, and of course water can still be liquid when it's 10 degrees out and even much colder.

I understand exactly what RT is getting at. Pure water, technically, can't get colder than 32 degrees in its' liquid form. It turns into ice at that point. Even if its' highly unpure, the freezing point isn't altered that much.

But the real question here, and one that I honestly don't know the answer to and can't find an answer to, is what temperature water turns to ice provided its' being violently disturbed every couple of minutes. I've seen waterfalls freeze, so it's possible for rapid moving water to freeze, but there's a significant difference between moving water and a violent disruption of the water's surface by jumping in it.

Basically, what would happen if you put a bowl of water into your freezer and repeatedly dropped something heavy into it? Would the temperature of the water approach 0 degrees without freezing? Or, would the repeated violent motion of the water create enough molecular friction that the reason it doesn't freeze is because it doesn't actually get that cold?
