The push point pin is sharp so when handling it be sure not to injure yourself.
Experience Level Needed:
Although this is a science based experiment, no science knowledge is required. Anyone is able to conduct the experiment. It is a great experiment for kids as long as an adult is present. Ages advised are 8 and over.

Step 1: Using a Pushpin to Make Holes in Water Bottle Top
Be careful when make the holes to not injure yourself from the push pin which has a sharp tip.
Step 2: Using a Glue to Put the Bottle Cap on the CD
Step 3: Make Sure Glue Is Dry
If done correctly the side of the bottle cap with the holes in it should be face up and the glue part of the bottle cap should be on the CD so that none hole of the CD is able to be seen.
After the step is complete the appartus should look like the picture.
Step 4: Placing the Ballon on the Bottle Cap
Inflate the ballon to its maximum capacity. Next, quickly strech the opening of your ballon over the closed bottle cap.It is very important that the bottle cap is closed or all of the air will leave through the bottle cap. The step should also be done quickly so that no air is allowed to leave the ballon before it is placed over the closed bottle cap.
Step 5: Hovering
Make sure this step is also on a large, smooth surface such as a wood floor or countertop.
Open the bottle cap and allow the ballon to hover, allowing air to be let out of the ballon. If done correctly, the ballon and CD shpuld hover like a hovercraft for about 30 seconds.
Step 6: Trouble Shooting
If your ballon didn't hover, dont worry! Here are some things that might have gone wrong.
-Your ballon must be completely inflated in order for the experiment to work.
-The bottle cap must be closed when you are putting the ballon on, and open when you wish to hover.
-The glue must be completly dried before adding the ballon.
-If the bottle cap won't stay in place on the CD, try stronger glue or a hot glue gun.
-The experiment must be conducted on a flat, smooth surface.
-A large enough ballon must be used so that enough air is able to move the CD. Dont use a small ballon.
