Tom thought it looked just like a glass of water, Even though it the jar was empty. He was puzzled. Was it a mind trick? Tom didn't know. But what he did know was that it was time to go to school.

Tom was now at school and in a boring lesson when suddenly he saw the exact same jar that he had seen at home.

When it was break time Tom ran to the place where he had spotted the jar but found it had moved again to the other side of the playground. "Strange jar," Tom thought.
