Bulgarian's like their Vodka

Today, I visited my Bulgarian friend in her apartment.  When I opened the freezer, I noticed that she had a vodka bottle in there, but the liquid was not frozen.  This is because the freezing point of alcohol is lower than the freezing point of water. Water´s freezing point is 0 degrees Celcius, while alcohol's freezing point is -114 degrees Celcius.  The alcohol won't freeze because the freezer was set to freeze water (to make ice), so it wasn't cold enought to freeze the vodka.
