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.
A fight breaks out, and Isaac Newton watches the quarrel and draws conclusions about forces based on his observations. Each boy is considered a mass, and each of their pushes is a force. At the end of the scuffle, Newton labels his conclusions "The Laws of Motion." This clip is an excellent depiction of Newton's laws of motion in a real-world context.
