      The phenomenon of atmospheric pressure–the weight of air bearing down on us–is not self-evident because air within us exerts an equal outward force. The phenomenon of air pressure was fist elucidated by a German scientist and revealed in a remarkable demonstration as reenacted this video. It is widely known as the Magdeburg hemisphere demonstration.
