Hot Water Experiment

What will happen to hot water outside on an extremely cold day?

Here are some of our students' predictions:
"It will turn to cold water."
"It will turn to ice."
"It will melt the snow."
"It will turn to frozen."
"It's going to evaporate into smoke."
"It's gonna turn warm."

We conducted an experiment to find the answer to our question. First we boiled hot water in a kettle, and then poured it into a cup. We took the hot water outside, and threw it up into the cold air. The hot water instantly turned into ice crystals! Look carefully at the picture above to see the ice crystals.
