Once upon a time, there was a little boy named Tim. He liked to design things. One day, he found a weird piece of metal. He wanted to make something special with it.
Tim showed the metal to his friend, Sam. Sam said, "That's a weird metal! What will you design with it?" Tim thought hard and said, "I want to make a big, strong robot!" But Sam wanted to make a fast car with the metal. They both wanted to use the metal, but they could not agree on what to make.
Tim and Sam talked and talked. They thought of a great idea. They would work together to design a robot car! It would be big, strong, and fast. They were both happy and started to work on their new project. And they became even better friends.
