What happens when you put a water bottle in the freezer?
So, when water freezes, the molecules take up more space, and the ice ends up being even /bigger/ than the water was. If you were to put that water in a closed container in the freezer, then it would still get bigger. What happens to the container depends on what sort of a container it is.
Will a glass of water break in the freezer?
Unlike most things, water actually expands as it freezes. With that being said, if your container contains liquid (or foods high in water content), it might break due to the pressure put on it by the liquid inside of it. Also, not all glass is recommended for freezing.

How long does it take for a drink to get cold in the freezer?
While a regular drink may take 30-60 minutes to cool down in a freezer, but wrapping it in a paper towel you can speed up this process and have a ready to drink beverage in 20-30 minutes.

Does hot water freeze faster?
Hot water can in fact freeze faster than cold water for a wide range of experimental conditions. This phenomenon is extremely counterintuitive, and surprising even to most scientists, but it is in fact real. The phenomenon that hot water may freeze faster than cold is often called the Mpemba effect.
Is the mpemba effect real?
Under our definition of the Mpemba effect, akin to the definition in the ‘original’ paper by Mpemba & Osborne8 (in which they documented “the time for water to start freezing”) we are forced to conclude that the ‘Mpemba effect’ is not a genuine physical effect and is a scientific fallacy.
