Chris Hadfield Brushes His Teeth in Space

Canadian astronaut Chris Hadfield has a big Twitter following, now hes a YouTube sensation as well, with "Chris Hadfield Brushes His Teeth in Space" receiving thousands of hits. Hadfield filmed the video aboard the International Space Station in answer to a viewer's question: "Is it challenging to brush your teeth in space without getting toothpaste up your nose?" In the video, Hadfield demonstrates how to maintain oral hygiene in a weightless environment (once you've corralled your floating toothbrush). And no, Hadfield says- toothpaste doesn't get up your nose, since there's no force to push it up there.
