Haha this is one of the most classical "story". I am not sure if this really happened before, but probably expanding 200 bar of gas in a room(I assume close system) will definitely get all the windows broken

Well, on the TV show mythbusters they made that experiment, I don't remember what kind of gas they used (probably just air) or what pressure but it went trought a concret wall easy, it probably could be an interesting experience in a lab haha.

This is really scary!!!! The cylinder probably even heavier than me!!
