  • How Building Implosions Work | HowStuffWorks

    Strictly speaking, an implosion is an event where something collapses inward, because the external atmospheric pressure is greater than the internal pressure. For example, if you pumped the air out of a glass tube, it might implode. A building implosion isn't truly an implosion -- atmospheric pressure doesn't pull or push the structure inward, gravity makes it collapse.
