Soap is made up of millions of tiny parts called molecules. Each molecule has a head and a tail. The head likes water and the tail likes dirt. The soap molecules surround the pieces of dirt with their tails sticking into the dirt, and their heads into the water. This loosens the dirt, and it floats off into the water, leaving your clothes nice and clean!
What is soap made of?
It's made of fats, or oils, and chemicals. Soap also has perfume in it to make it smell nice, and dyes to make it look pretty.
