Was watching the Discovery Chanel last night. Submarines the ultimate guide. They did a demo in the escape training chamber, of the way compressed air expands while ascending. They had a silver bag which was filled with compressed air and released from the bottom of the tank. You could see the bag start to expand and then burst! Would be great for showing to new students.
