Waiting to Exhale . . .

A silent but strong force exists all around us waiting for the right moment to strike.

Force = (Air Pressure)(Area)

do this at home. . .

  Pressure in a Fluid (the Air)

There is a ~15 mile column of air over the drum and around the drum.

The weight of this fluid over the drum is not insignificant.

The area of the drum is ~2500 square inches
F = PA
So the Force on the outside of the drum is ~ 40,000 lbs!!

Pascal's Principle 1,2,3

Archimede's Principle I
When an object is completely or partially immersed in a fluid, the fluid exerts an upward force on the object equal to the weight of the fluid displaced by the object.
