In space, even simple tasks like washing your hands can be tough, but thanks to advancements in sanitary technology, cleanliness is just a pouch and squeeze away. The Canadian Space Agency has developed no-rinse soap just for that task. Continue reading to see how it works.
In a recent Q&A session beamed back from the ISS, astronaut Chris Hadfield shows how this no-rinse soap works: pour the solution - a mix of hot and cold water and soap - into thin air from a straw attached to a pouch until it gathers into a ball and floats upwards before he grabs it. The solution then clings to your hand and is then rubbed in and afterwards, you use a towel to dry yourself off.
