Chris Hadfield, an Ontario native, is an astronaut who has created a series of YouTube videos that show Earthlings like ourselves how different life would be like without gravity. Mr. Hadfield's videos show us his day-to-day experiences on board the International Space station since December 2012. There are many videos, for example, of how the crew's sleeping and eating is different from life on Earth.
Safari Children's Dentistry's favorite video is, of course, "Chris Hadfield Brushes his Teeth in Space." No matter where we are in the galaxy, it is always good to carry a toothbrush and a tube of toothpaste!
