• A clothespin

• A bottle cap

• An old CD

What is the primary purpose of the balloon in the hovercraft project?

• To serve as a handle for the hovercraft

• To act as a decorative element

• To create a layer of air that reduces friction

• To provide weight to the hovercraft

What role does the bottle cap play in the hovercraft assembly?

• It provides decoration

• It acts as a base for the hovercraft

• It holds the balloon in place

• It is used to balance the hovercraft

Why does the hovercraft move more freely compared to a CD sliding on a table?

• The table is smoother

• The CD is more aerodynamic

• The air layer reduces friction

• The hovercraft is lighter

How does the air layer between the CD and the table affect friction?

• It reduces friction significantly

• It has no effect on friction

• It eliminates friction completely

• It increases friction
