Professor O will help you learn: When air rushes out of the back of the balloon, it pushes the ghost forward along the string. That is Newton's third law in action: every push has an equal push the other way, the same idea that launches real rockets.
⚠️ Balloons are a choking hazard for young children, so an adult should blow them up and pick up any burst pieces straight away. Check for latex allergies and use latex-free balloons if needed. Keep the string low so no one walks into it.
Play through the project step by step, with narration read aloud.

Make it your own: Race a small balloon ghost against a big one, or tilt the string uphill and see whether your ghost can still reach the end.
