Music Notes in a Water Bubble

Many of us have conducted sound experiments using string or slinkies to show what a sound wave looks like.  But astronauts on the International Space Station have a really great way to show sound waves coming from a speaker.  Without gravity, water forms a sphere, so in space you get to see little balls of water.  Take a look as an astronaut uses these balls of water and an old speaker to show us what happens as sound travels through a medium, in this case water.  Too bad we can’t do this on earth!!
