                          Build a Hover Craft From Balloon

                                 

Things You Will Need:

*A balloon

*An old Cd

*Hot Glue or epoxy

*A water bottle cap(any which works well)

What To Do Now:

* Get The bottle cap and poke a  medium size hole in the center.

*Now,get the CD and at the top of  its center hole fix the cap 

of the water bottle at the center hole of the CD.

*Fix it with hot glue to keep it airtight.

*Now wrap the balloon's end at the top of the cap.

*Your hover craft balloon is almost ready,

Blow it up from the bottom and leave it on the surface,

and u are ready to go.

What Is Happening:

*The flow of air created by the balloon between the surface and the CD make the friction

less applicable to the surface.And the balloon floats easily over a smooth surface.

Try yourself:

Think,

*Will the Hower craft will work better if,

*If u use a big surface area instead of Cd

*If u use a big balloon.

*will a helium balloon will work better then this air filled balloon.
