A stranger comes to the park. He has a small box with strange buttons and lights. "Can you solve this puzzle before your lunch ends?" he asks.

The group looks at the box. It changes colors and sounds when they touch it. "We need to work fast," says Anna. "What if this box can tell the future if we solve it?"

They press buttons together and watch. The box shows quick pictures. Everyone feels happy. "We did it!" says Mike. "Maybe the future is about teamwork."
