How to make a hovercraft

To make a hovercraft first we need these materials .

You will need a Bottle cap

 An Old CD 

A Balloon

And Hot Glue 

First you get old CD. Glue the bottle cap on the middle of the old CD. Get the balloon and put it on top of the cap. Pull your bottle cap count to ten while you blow. When you stopped counting to ten push on the cap. Then put it on a table or hard surface not a carpet. And then pull the cap and let it hover.

How it hovers is the balloon pushes the air down and the air to slightly carry the CD. Gently push it and that is a hovercraft. A hovercraft can’t hover on carpet water and rocky concrete.
