How Do Astronauts Sip Drinks Or Hot Coffee In Space
395In this video, we'll show you how astronauts sip drinks like coffee in space! Find out the unique methods they use to enjoy their beverages in zero gravity.
Ever wondered how astronauts enjoy a hot cup of coffee in zero gravity? In the absence of gravity, liquids tend to stick to themselves and to any surface they touch. This means that if astronauts used regular cups, the coffee would cling to the sides and bottom, requiring them to shake the cup towards their face, hoping a bit of the hot liquid would break free and float into their mouths—not exactly safe! Instead, they use specially designed cups shaped to take advantage of capillary force and surface tension. This unique design allows the coffee to gently creep up the sides and settle right at the lip, making it easy for astronauts to sip safely in space.
