Long ago, children played like children do today. They got dirty from running around. Older people got
dirty from working all day. But then there was no soap. What did people do to get clean?
At first, people just went into a lake. They washed in the water. But then learned to use other things with
the water. They put plants in a fire until they turned black. In this way,they made ashes. People used the ashes
like soap. They also used oil like soap. But these were not very good.
The first soaps were hard to make. First water was put in a pot. Then fat was added. Oil and ash were
mixed in the pot, too. Then it was put on a fire. Everything got very hot. Salt was added. After a while the
fat came to the top. When the cooked fat was taken out, it got hard. This was the first soap.
The soap we use today is very different. Things were put in to make it smell good. Something is added
to give it a nice color. Some soaps are white. Others are yellow, green, or blue. Soap is also cut in different
ways. It can be round or square.
What is soap used for? We all know that it is needed to wash things. But did you know that a kind of
soap is used to oil machines? This makes them work well. Another kind of soap is put in oil to make your
car run better.
