- Abstract
When the atmospheric pressure decreases, the higher air pressure in the can is able to push the balloon up, causing the straw to tilt down and point to a lower number of millimeters. See the Science 101 column on buoyancy under Online Resources.) The rising air moves up and then eventually spreads out horizontally, and you end up with fewer air molecules pushing down on the ground in that region, resulting in lower air pressure. HOW THE BAROMETER WORKS When the atmospheric pressure increases, the air pushes down on the balloon, causing the pointer end of the straw to tilt up to a higher number of millimeters.
