Israeli Scientists Freeze Water By Warming It
ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."
It's not quite Hell, but it's an impressive step in that direction...
By reading the title only, I thought the overflow-bug of water was finally found.
An Australian from Mitta Mitta who failed a dowsing test claimed that he only failed because the water was "electrically charged wrong".

Obviously Chemists are more nationalistic than Physicists...
Sure, but do you really want your water pipes freezing in the summer instead?
One of these guys managed to turn water into wine 2000 years ago...
You clearly must be an American, since you compare beer to water. Over here in the old world, we know there is a difference by the taste for one.

A pyroelectric lithium tantalate ice cube tray? In animal shapes?
You are welcome on my lawn.
Yeah, we don't appreciate Apple products over here.

Hmm, water ice that is stable at a higher temperature than liquid water? Can anyone say ice-9?
