Video: Astronaut Don Pettit Plays Space Station Vacuum Cleaner As Didgeridoo

When he’s not busy with his full-time gig, NASA Astronaut Don Pettit takes the time to run some of his own personal science experiments. His latest? A zero-gravity didgeridoo performance — for science.

Actually, it’s not really a didgeridoo: Pettit takes a space station vacuum cleaner and cleaves off half of it, attaching two different end pieces and measuring their resonance against a couple drops of water, which throb excitingly and shed mini-droplets. Even if you’re not interested in tribal music or liquid surface tension in space, the video is worth watching if only for the wacky costume change.
