The Canadian Space Agency has an YouTube channel in which they share videos about many experiments done without gravity. Their main astronaut is Chris Hadfield, who tries to brush his teeth inside the International Space Station in the film above. This proves to be extremely hard, as there isn’t a sink to soak the toothbrush. Be sure to note that his microphone floats every time it is not grabbed by him.
The International Space Station is a habitable artificial satellite developed by a joint international team comprising 5 space agencies. The US, Russia, Japan and the European Union work together to maintain the station active. It is divided into an American section and a Russian one. Brazil has been a part of the ISS, but the country has revoked its position due to lack of capital available to invest in the project.
Below, I have also shared two other videos from Hadfield. The first one shows a towel being wrung out as part of an experiment designed by Canadian students (the water doesn’t fall, obviously). In the second, we can see the mechanisms that are used to control the ISS.
