About a year ago I brought back a bottle of glacial meltwater from Alaska. It was frozen when I collected it and once melted looked perfectly clear. A few months ago, I noticed something that looked like a small clump of hair at the bottom of the glass, which has been growing slowly ever since (
see photo, left). I have not removed the bottle top since I collected it.Can anyone tell me what it is and, if it is alive and growing, where is it getting its nutrients from?
