For those of you who hate brushing your teeth under normal circumstances, think about how much harder it is to clean those pearly whites in space, with zero gravity and no sink to get water from or spit into afterwards.

In another in his series of entertaining how-to videos from space, International Space Station Commander Chris Hadfield shows how to take care of those chompers in space. Does the toothpaste go up your nose? How do you get the toothbrush wet in the first place?

Check out the below video in which Hadfield answers those questions and more. And here's a spoiler: he has a unique way of cleaning his toothbrush post usage.


Williams made a video presentation on her latest space expedition, 'Expedition 33', that was launched from Biakonur Cosmodrome in Kazakhstan July 15, 2012. It began with a narration of the preparatory drill for space travel and then showed the working environment inside the space station. The video described the nature of the experiments conducted aboard as well as the space walk performance.

The most interesting part came when it showed how an astronaut spends a typical day in space and focussed on the challenges'' involved in routine activities like brushing one's teeth and using the toilet given that there is no gravity.

In space, we see 16 sunrises and 16 sunsets within a span of 24 hours. Naturally, you cannot wake up every time the sun rises and go to sleep once it is dark. We set our day to GMT and wake up around 6.00 am. Our work hours span 8.00 am to 7.00 pm and the Command Centre back here on Earth gives us assignments for the day,'' she said. In the beginning it all looks very clumsy but soon you learn to float around smoothly and get accustomed to living without gravity.''

Williams appealed to the children to take an interest in space exploration. I am really looking forward to India's participation in the space programme in a big way,'' she said. It entails creativity and requires imagination.'' Speaking about the International Space Station Williams said, It is a collaborative venture where different countries are participating. It has brought the world together.''

She hoped for an ISRO-NASA collaboration in future that would open up opportunities for young Indians interested in pursuing a career in space exploration.

Williams was the commander of Expedition 33 where she was accompanied by Russian Soyuz commander Yuri Malenchenko and Japan Aerospace Exploration Agency's flight engineer Akihiko Hoshide. Her team spent four months conducting a wide range of experiments. Williams and Hoshide performed three space walks to replace a component and repair an ammonia leak on a radiator. The crew returned to earth safely on November 18, 2012 after having spent 127 days in space.
Williams' India visit began April 1. She met with students at the National Science Centre in New Delhi and Science City in Kolkata and plans to end her trip
