We all know who Benjamin Franklin was. He was a very famous American statesman. He was also the first man to discover electricity. Franklin liked to study and to learn about new things. One day he heard from a friend that something black in colour holds the heat better than something white in colour. Franklin wanted to find out if this was true or not.

There was snow on the ground at the time. So he put two large pieces of cloth over the snow. One piece of cloth was black in colour, the other piece was white. Then he waited until the sun began to shine. After several hours he looked under the pieces of cloth and saw that the snow under the black cloth melted much faster than the snow under the white cloth. This proved to him that the black cloth held the heat better than the white cloth.

Soon after this, people began to wear white hats and white clothes during the summer because they were cooler.
