EQUIPMENT
AND MATERIALS:
|
CD , balloon and a bottle cap.
|
PROCEDURE:
|
Step 1:First we used a hot glue gun to glue the bottle cap on the CD.
Step 2:Next we got a balloon and blew up the balloon until it was fully inflated. Also we twisted the end of the balloon so the air doesn’t come out.
Step 3:We stretch the balloon to put an end on the bottle cap.
Step 4:We opened the cap and placed the CD on the table.
Step 5:Finally we untwist the balloon and let it go.

OBSERVATIONS/RESULTS:
|
I saw the balloon hovercraft move around on the table.

CONCLUSION:
|
The air from the balloon creates a cushion of moving air between the disc and the CD and reduces the friction across the surface.
