How astronauts brush their teeth

Video: So how on earth do you brush your teeth in space?

EVER wondered how astronauts brush their teeth in space without getting toothpaste up their nose?

The Canadian Space Agency has uploaded a clip of Chris Hadfield, the commander of Expedition 35 aboard the International Space Station, brushing his teeth.

The video was posted in response to a question about whether it is difficult to brush your teeth in space "without getting toothpaste up your nose".

There's no running water on the space station, instead water is pushed through a straw from a bag. Hadfield uses the water to get his tooth brush nice and wet.

He then puts regular toothpaste on his regular toothbrush, before scrubbing his pearly whites, just like normal.

But instead of spitting the toothpaste out, in space you have to swallow.

"It's edible - it won't kill you. And what else am I meant to do, put it in a rag and have a dirty rag - it doesn't make any sense," Hadfield says.

And so no, at no stage does the toothpaste go up his nose.

In previous videos, Hadfield showed viewers how astronauts clip their nails, get their hair cut, prepare meals, wash their hands and work out in zero gravity.
