Snazzy Space Stunts: NASA astronaut's messy experiment to show how zero gravity works
[]
NASA astronaut Jack Fischer has made a video of a messy yet enlightening experiment aboard the International Space Station to show just how zero gravity works.
 
Fischer placed a straw inside a fruit juice bottle and blew through it. A bubble came out and as he continued to blow, the bubble grew in size before it covered his face. Fischer then popped the bubble, resulting in a wet mess floating around.
