How does a hovercraft hover
HYPOTHESIS
I predict that it is going io do not wook.
Bottle lid, a balloon and a disc Step 1:Using a hot glue gun glue the battle c
Cap over the CD hole.
Step 2:Blow up a balloonn. When it is fully inflated twist the end so no air come out.
Step 3:Stretch the balloon over the end of the bottle cap.
Step 4:Open up the cap and place the CD on the surface.
Step 5:Untwist balloon and let go.
It spinning around THE air from the balloon creates a cushion of moving air between the disc and the CD and reduces the friction across the surface.
Hi Frank. I like your science writing and how you followed the scientific method to describe your experiment to your readers. I had the same idea of a balloon hovercraft but we're going to do a variation of your experiment and will be trying to find out how much weight a hovercraft can hold. Maybe go check your spelling. I don't really understand what some of the words mean. I hope you can see my experiment on my blog soon
