Where is the best place to conduct gravitational experiments? In space, of course. In a video posted on August 11, NASA’s Expedition 52 flight engineer Jack Fischer demonstrated how to create a giant water bubble.
The video shows Fischer using a straw and a bottle full of pink liquid to blow air into the liquid to create a bubble around his face. When the bubble explodes, the water flies into the air in smaller bubbles, showing how liquid floats in zero gravity. Credit: NASA Johnson Space Center via Storyful
