NASA on monday released an awesome video in which its crew members are seen enjoying making pizza in space. Because everything in microgravity floats, the astronauts were careful to tether things down while slapping ingredients onto their pizza. The ingredients used to make these space pizzas were also chosen carefully, which could be slapped easily in the pizza and do not float in space. The video shows astronauts playing with their food as the pizza bases float in space. Watch this video to find out more.
