How does the soap work?

“Pin-shaped soap molecules have one end that bonds with water (the hydrophilic head) and the other end that bonds with oils and fats (the hydrophobic tail). When you build up a soapy lather, the molecules help lift the dirt, oil and germs from your skin. Then, rinsing with clean water washes it all away.”
