  1. When I was a kid in the '40s and '50s, it was common to see that demonstrated in a department store with a beach ball, using the exhaust stream of a vacuum cleaner.

    Anybody else remember that?

    1. It's 14.7 PSI...Pounds per square INCH, not foot.

      So change your numbers by a factor of 144. (12 x 12).
