Dry Ice...

So while my wife and I enjoyed a lovely vacation last week. But while we were gone, my son and his buddies got a hold of a 50 pound block of dry ice and decided it would be FUN to put a said 50 pound block of dry ice in the swimming pool. After they put dry ice in 2 liter bottles and threw them in. They even went as far as to remove the cover. I know this as they made the mistake of posting the video on their facebook, which both my wife and I enjoyed watching from our hotel room in Hawaii...
