Discussion questions
Talk about it
Air is matter, even though we can't see it. A fast-moving ring of air carries enough force to shove a flying drone.
- What evidence in the video shows that air can push on things?
- Why does adding fog let us see the air ring?
- The ring holds together as it travels. What might keep it from spreading apart?
