measures 20 by 10 by 10 feet. On each square inch of the building, there is 2 pounds of pressure from the inside that

is not balanced by air pressure outside the building. On the ceiling, that adds up to an unbalanced pressure of 57,

600 pounds. The pressure on the four walls adds up to 172,800 pounds.

If windows are open in the building, some of the inside air will rush out through them. This will balance the pressure

inside and outside the building. But if the windows are shut tightly, the enormous inside pressure may cause the

building to burst. Unfortunately, heavy rain and hail often occur in thunderstorms that later produce tornadoes. So

people frequently shut all windows to protect their property.

This may cause far worse damage later. For the same

reason, tornado cellars must have an air vent. Otherwise, the cellar door might be blown out when a tornado passes

over it.
