Astronaut Don Pettit is a national treasure. He's been to space three times—once for a six-month stay on the ISS. On every mission, he's found time to make huge contributions to the public communication of science, including making a series of amazing "Science Saturday" videos and inventing (from spare parts he found lying around the ISS) a system to help the space station take clearer, sharper pictures of the Earth at night.
Pettit went to space with an international crew in December 2011 and is currently in space. This new video—where he demonstrates the way a small electric charge can manipulate the behavior of water droplets in microgravity—is a great addition to his oeuvre!
