Freeze a 1/3 filled bottle overnight, and then you have one giant ice cube so when you fill the rest with water you get icy cold refreshing water all day long.
I am a cook and this has been a literal lifesaver for me at work in the summer.

I like to freeze it horizontally so I get a column of ice, and all of the water I put in the next day is in contact with it.
