centrifugal and Science

Centrifugal force is what keeps a string with a ball on the end taut when you whirl it around. A centrifuge is a machine that uses centrifugal force. At the end of a washing machine's cycle, it becomes a weak and simple centrifuge as it whirls the water out of your clothes. Centrifuges hundreds of thousands of times as powerful are essential to nuclear technology and drug manufacturing. Part of an astronaut's training occurs in a centrifuge that generates force equal to several times the force of gravity (about like a washing machine) to get them used to the forces they'll encounter in a real space mission.
