Here’s where life gets fun. You can experiment right now. Fill one ice cube tray with hot tap water and another with cold. Which freezes faster? Spoiler: the hot water often wins due to the Mpemba effect—a weird, real phenomenon where hot water can freeze faster than cold!
Or try this: put a plastic bottle of water in the freezer. Set a timer for 90 minutes, then gently tap it. If it’s supercooled, you’ll see it instantly turn to slush right before your eyes. It’s like instant magic you can drink.
The Real Answer (Finally!)
For a standard ice cube tray in a 0°F freezer? Expect about 1 to 2 hours. For a full water bottle? 2.5 to 4 hours. For a large stockpot of water? Overnight, likely 6 to 12 hours.
But remember: these are ballpark figures. Your freezer’s age, how full it is, and even the humidity in your kitchen all play a role. The real answer is: “It depends—but you can find out in an afternoon!”
