In a test, researcher Cecil Adams put equal quantities of hot water (125 degrees Fahrenheit) and cold water (38 degrees) into ice cube trays, and then placed them in the freezer. The results? The cold water froze about 10 or 15 minutes faster than the hot water. So the old wive’s tale of hot water freezing faster appears to be a myth.

In a recent email from an astute customer (Thanks, Marc!), he told us that when water is heated up and then cooled, it will freeze faster than water that has been at that temperature the whole time. So, now ya know the rest of the story!
