[Rain Man]

I've always wondered what would happen if you opened a shaken soda under pressure.

I was at the Smithsonian a while back, and they had on display a styrofoam cup that had been left in a submersible that went down to some deep depth where it was under extreme pressure. The amazing thing was that it didn't crush the cup, but rather it miniaturized it. My theory is that it collapsed all of the air that's evenly distributed in styrofoam, and because the material bound it together, it pulled in on itself.
