In Antarctica, there is a crimson red stream that occasionally pours out of Taylor Glacier forming a waterfall that makes it look like the ice is bleeding. Maybe this glacier is a young lady and we found its vagina. Ba Dum Tss!...

Apparently any material that melts can be made into glass. I theory by cooling off a molten material before its molecules have time to realign into what they were before being melted, of course this implies a lot of conditions have to be met. But some very smart guys discovered that a combination of Aluminum, Oxygen and Nitrogen can be transformed into really unbreakable glass.
