Once upon a time, in a world full of machines, there was a young scientist named Sam. Sam had a robot friend named Code, and together they traveled around the world, testing new materials to help machines last longer. One day, they found a special coating that could protect against rust and scratches. But there was a problem! They had to figure out how to make the coating faster without wasting time or money. Sam and Code used their special tool that could predict which coating would work best—without doing hundreds of tests!

MORAL: By using smart tools and understanding materials, scientists can find the best solutions faster, just like Sam and Code did!
