Neat sight!

We have done the "hot water freezes faster" experiment at home (just to
prove it to my husband who didn't believe me when I told him ... when's he
gonna learn that I know everything ;)) in the freezer, and it really does
freeze faster. However, it freezes differently, also. The ice that results
in an ordinary ice tray in the freezer when cold water is frozen is "normal"
ice, safe to put into your ice tea or Pepsi Cola. the ice frozen from very
hot water, while freezing faster, is not always so safe. it has a tendency
to explode rather violently when put into anything warm or hot, like freshly
made hot tea that is being iced or Pepsi that has been sitting in a closet
rather than the refrigerator. And if put into cold liquid, such as Pepsi
that cames from the refrigerator, it has a tendency to "slush up" more than
ice made with cold water.

Therefore, while I don't really understand the reasons for hot water
freezing faster, it isn't practical to freeze hot water into ice to be used
for drinking purposes unless you like exploding ice. :)

Try it ... I'm really not kidding.
