Actually, miniature black holes do pop in and out of existance every once in a while.
And about the glass, it is technically a liquid because it lacks any crystalline structure.
Someone also mentioned that water's heavier when it's hot. That's only partially correct. The maximum density of water is achieved at 4 degrees celsius.
