I've never met a kid who didn't want to be launched into space. Kids' notions of what it's like to be an astronaut tend to be pretty grand, and vivid imaginations compounded by the influence of movies and television often lead them to think a big part of the job consists of the heroic destruction of renegade asteroids.
Canadian astronaut and former commander of the International Space Station Chris Hadfield has a series of informational videos demonstrating the reality of living life suspended in zero gravity. The videos are fascinating (despite the lack of asteroid explosions) and can be fun and instructive ways to amp up science lessons on the physics of space.
Watch the above video to see how Hadfield brushes his teeth in space, and be sure to visit the Canadian Space Agency's YouTube channel for more of Hadfield's videos describing everyday life in a space station, from how to make a peanut butter sandwich to what happens when you cry in zero gravity.
