True or false
Astronauts in space shuttles use ‘no-rinse’ shampoo to wash their hair.
True. Water and soap stick to the skin in a state of weightlessness. Therefore, instead of normal shampoos that require water, astronauts use no-rinse shampoos. These shampoos, when massaged on to the head, give a good lather; which is then wiped off by using a towel.
