Vacuum Chamber Experiment: Balloons Reveal Atmospheric Pressure Secrets

Astana, Kazakhstan - June 2, 2025 - A simple yet fascinating physics experiment was recently captured on video and shared online. The experiment involved placing two vacuum-sealed balloons inside a vacuum chamber and observing their reaction as the air was gradually removed. The video shows the balloons slowly expanding as the external pressure decreases, a clear demonstration of how atmospheric pressure affects sealed objects. Almas Topeyev, the author of the video, explains, "When two vacuum-sealed balloons are placed in a vacuum chamber, they are initially compressed due to the higher atmospheric pressure outside. As air is removed from the chamber, the external pressure decreases, and the pressure difference diminishes, allowing the balloons to expand slightly." The experiment's visual clarity and simple explanation make it a great educational tool for illustrating basic physics principles. The experiment's success highlights the power of simple demonstrations in making complex scientific concepts accessible to everyone.
