This is just a curiosity that I felt like sharing. Cj has had this big wine bottle that she's used to store pennies in for a long time... about 20 years, according to her. It was about half full. I guess that was just a lot of pressure being exerted against the glass for too long, because the other day, it just gave out. As far as we know, we didn't kick it or hit it with anything... it just... failed. Strangely, just the bottom broke; the top part is still intact and upright.
