Mold can float...

Were you aware that mold can actually grow in a liquid? Now I guess I'd never really pondered this scenario before. But, today I went to the fridge, happily preparing to partake of some apple juice and poured a glass and then...to my suprise, there were things floating in it. Ok, can we say "gag". I quickly dumped the rest of the apple juice down the drain including my glass full. Disgusting, to say the least. Guess I'm just slow to realize this in my mid 30's.
