CWaters A suction cup works because energy removed the air inside the
cup. A hard hat diver only 32 feet under water can have his whole body
squeezed into the helmet(hat) because air pressure in his helmet became
less than the water pressure against his rubber suit. This is the same
physics of a suction cup. Bert PS Hard hat divers call that the
"big squeeze"
