Questions for Discussion: Air Power: Making a Hovercraft
How did the cast know that air was being pushed under the plate if they couldn't see it? If you used a bigger balloon, do you think the hovercraft (plate) would be easier or harder to move? Explain your reasoning. Where does the air come from in a real hovercraft, such as the one moving over the grass in the video segment? Why do you think that the hovercraft was invented? In what situation would it be a good choice for a vehicle? What are some of the important design features in a hovercraft?
