Fastest way to freeze 1 Gallon of Water

  1. Apr 10, 2017 #1
    I need to freeze a gallon of water in my dorm room mini fridge over night to prank my roommate. when turned up to the max, it will freeze water. but I'm wondering if placing ice or dry ice next to the jug would help it freeze faster over night. I'm worried the fridge would spend more energy trying to keep the added ice frozen, then spend it on freezing the jug.
