STEP3 - Let's take your hovercraft for a test drive!
How can I move a CD with a bottle cap?
-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.
How does CD hovercraft work?
The small hole in the centre of the CD forces air escaping from the balloon downwards. This creates an opposite force upwards which lifts the hovercraft off the ground, explained by Newton's Third Law of Motion. The CD spreads out this force evenly along the bottom of the hovercraft.

How does a homemade hovercraft work?
How does it work? The air flow created by the balloon causes a cushion of moving air between the disc and the surface. This lifts the CD and reduces the friction which allows the disc to hover freely. Large scale hovercraft are capable of traveling over land, snow and water.

How do you make a balloon and paper plate hovercraft?
Pinch the end of the balloon to hold the air inside. Flip the plate upside down and place on a flat surface. Release the balloon. The air pressure from the balloon will cause an air pocket to form under the plate, allowing it to rise just slightly and move across the plate until the balloon runs out of air.
How do hovercrafts move forward?
Hovercraft use blowers to produce a large volume of air below the hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface.
Can hovercrafts go on land?
In fact, that's exactly what you're doing—a hovercraft is a vehicle that glides over a smooth surface on a cushion of air. Because a hovercraft can travel over flat land or water, it is an amphibious vehicle.

How to make a hovercraft?from theresjustonemommy.com
To make a hovercraft, line up the base of the drinking spout so it covers the hole in the CD. Use duct tape to secure the drinking spout. Make sure you completely seal around the spout, leaving no space for air to leak. Alternatively, you can use a hot glue gun to adhere the spout to the CD.

Why not add too much glue to a CD?
Make sure to not add too much glue because the extra glue adds weight that can negatively affect the experiment. 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.

Step 1: Materials
1. Any CD you don't want anymore. 2. A ballon. The party kind. 3. A water bottle lid. The one you pull open and push shut. 4. Glue gun.
Step 2: Make It
The lid i showed isn't what you need. You need the one off, like, Aquafina but the lid of this type. Take the lid and glue it over the hole on the CD. Make sure you can open and close the lid and that air can go through it. Attach the ballon to the opening of the lid. The part you suck the water through.
Step 3: How to Use It
1. Open the water bottle lid. 2. Blow air into the balloon through the bottom of the CD. 3. Close the water bottle lid so no air comes out. 4. Put the CD flat on a table/floor with the balloon on top. 5. Open the water bottle lid and let go.
Let's Try It
Using a pushpin, poke 3-4 holes around the center of a closed bottle cap used on a water bottle. The holes need to go all the way through the plastic of the cap. Make sure that the tamper-proof ring is removed so the lid can sit flat on the table.
How Does It Work
Hovercrafts use air to lift a vehicle off of a surface but there has to be a lot of it moving very fast, straight down. The CD Hovercraft is no exception. As the balloon contracts, air is pushed through the holes you punched in the bottle cap. This air escapes out from under the CD in all directions.
Take It Further
If the hovercraft doesn’t slide or spin easily, there are a couple of trouble-shooting steps you can take. Make sure the CD isn’t warped or cracked. If it is, just rebuild the hovercraft with an intact CD. If everything about the CD looks OK, poke larger or more holes into the bottle cap.
