Why should astronauts drink from this cup? #shortvideo

Have you ever wondered how astronauts drink liquids in zero gravity? Because liquids in zero gravity stick to themselves and anything they touch. Therefore, if they use regular cups, the liquid will stick to the sides of the cup or to the bottom, which forces them to shake the cup forcefully to release a little liquid to drink. This is a great danger to them, so they did it. By creating a cup with a distinctive design, which helps in moving the liquids inside it to a specific point and drinking from it with great ease
