Cut glass bottles in half with this trick!

Oh boy, glass chips in my mouth!

You wan to be REALLY careful with this. I think our water was too cold and it was too much of a temperature shock for the glass since the bottle cracked and splintered. It was loud, too! Luckily we decided to lower it in with tongs in case it did explode and we weren't hurt. We didn't have the guts to try it again with the other bottles.
