NASA astronaut makes zero-gravity cup to have coffee in space

NASA astronaut Donald Pettit, during his time on the International Space Station (ISS), invented a unique cup designed for drinking coffee in zero gravity. Traditional cups don't work in space due to the lack of gravity to pull the liquid down, leading to floating blobs of liquid. Pettit's cup, known as the Capillary Cup, utilizes capillary action to draw the coffee up the walls of the cup, allowing astronauts to drink it without it floating away. This innovation not only made enjoying coffee in space possible but also provided insights into fluid dynamics in microgravity, which could have applications in various scientific fields. The cup's design was inspired by the shape of a wine glass, and it has since become a symbol of how everyday challenges in space can lead to innovative solutions.
