NASA astronaut of Indian descent prepares for debut spacewalk by clearing water bag bubbles

Anil Menon, an Indian-origin NASA astronaut stationed at the International Space Station, posted a video showing the method for purging air bubbles from a spacesuit water pouch ahead of his maiden spacewalk scheduled for August. He explains that they manually centrifuge the bag by spinning it to gather the bubbles. Menon then proceeds to push the trapped air out through the tube.
