To moish01: I found this technical explaination:
Taking water for an example, its density is exactly 1. However the density of ice is around 0.8 because of air bubbles that get trapped during the freezing process. Lets say you put this liquid in a closed system (such as a beer bottle). Everyone knows density is weight / volume. Since the weight remains constant (you aren’t adding or subtracting anything from the closed beer bottle) that means you must change volume in order to decrease density. Since volume is on the bottom of the divisor it has an inverse relationship. That means you must increase volume to decrease density during the freezing process. We know that a beer bottle can only hold so much volume of liquid, so when that volume starts increasing its going to put pressure on the glass. This is about when it cracks and makes a mess. a bottle of beer is left in the freezer it will explode.
In other words the beer will explode-i know however the BMG/beer thing its just a joke!
If you want to get all analytical over here maybe we can come up with something that when BMG is in the freezer their ego expands when they are redt to thousands of girls, and then they feel the pressure when a thousand shadchanim and well meaning friends and relatives are running after them and by the time the freezer is open they are a mess – have exploded/are ready to explode, and are ready to run away!Lol!
