MythBusters: Moon Flag Waving Hoax
  • Physics → Newton's Laws of Motion → First Law

The MythBusters conduct a test at NASA to determine whether a flag on the moon would wave as it does in the video footage of the first moon landing. They find that momentum alone can keep a flag moving in a vacuum; wind is not needed.

Public Discussion Questions


  1. (before viewing): Do you think people really landed on the Moon, or were the landings faked? What evidence supports your claim? What evidence refutes your claim?
  2. (pause at 2:18): Explain using laws of motion and laws of conservation why the flag seemed to be "waving" in the vacuum chamber. How does this support the claim that astronauts indeed landed on the Moon?
