The Freaky Dynamics of Sound Waves in Water in Microgravity

More

Don Pettit, an astronaut on board the International Space Station, uses laptop speakers and an mp3 player to demonstrate the physics of sound in space. 250 miles above the surface of the Earth, the Space Station feels 88% of the gravitational pull we feel down here, but the spacecraft and everything in it are actually in free fall (aka in orbit), creating an almost zero-gravity environment called microgravity. Pettit's educational series, Science off the Sphere, is a collaboration with the American Physical Society. Turn up the audio to appreciate the ZZ Top soundtrack.
