Question:
mam,in ur hover craft experiment ,wat happen when there is air inside the ballon
Answer:
Hovercraft means a vehicle or craft that travels over land or water on a cushion of air provided by a downward blast.
So, using a CD and balloon when we make a hovercraft, it moves on the surface, due to air inside the balloon.
When there is no air inside the balloon, it stops moving.
