    When Ben Franklin was only a child, he always wanted to know about things. He was asking his father

and brothers "what" and "why".

    They couldn't always tell him what he wanted to know. When they couldn't tell him, Ben tried to find

out for himself.

    Many years Ben did find out things that no one knew before. The other boys would say, "That Ben

Franklin! He is always finding out something new."

    Ben lived close to the water. He liked to go there to see the boats. He saw how the wind blew them

across the water.

    One day Ben said to himself, "Why can't the wind help me float across the water? And I am going to try."

Ben got his big kite. He took hold of the kite string and ran with it. The wind took the kite up into the air.

Then Ben jumped into the water. The wind blew the kite high into the air. Ben began to float across the

water. Soon he was on the other side, and he had not worked at all.

    One boy shouted, "Look at Ben floating across the water! His kite takes him to the other side without

work!"

    "Yes," said another, "he is always finding new ways to do things."
