Washing Hands and Science

On the 20th of March our teacher showed us some science. He had a carton of milk, pepper and soap. He poured the milk in the bowl then put in the pepper. Then he put soap on his finger then he put his finger in the bowl. Then the pepper moved away from the soap. We were learning how to wash our hands properly. First obviously put soap on your hands then you turn on the tap. Rub your hands together then you do between your fingers. You do palm to palm and do it for 20 seconds and when your finish turns off the tap.
