CD Hovercraft





Introduction: CD Hovercraft

A CD hovercraft with a ballon. Great time waster. My first instructable.

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.

    Dude you should try putting mice on it!

    now ive done these before, and ive straped bottle rockets to CD's but how many of you have done one of these bad boys with a bottle rocket straped to the side as such -->cd OI <--bottle rocket, so its sideways, not up. it is so cool

    you can also just get a normal screw on cap, put a small hole on the top side, and glue it so the underside is facing up

    if you use clay, it is easier to blow in air. you can also use blue-ack or some sticky tac

    does it go off the ground

    Haha, it's great :) You can use clay instead of gluing the bottle lid.

    This looks to me like a slightly different version of the CD hovercraft as it uses a drink bottle with a spout. It's great to have two different version of the same thing, as there are multiple right ways to build something.

    Yeah, i guess you're right. Short, sweet, and simple. I love these instructables that I don't even have to get up for to make.

    I made one of these in May and it really does work, for about 5 seconds. But it was fun playing air hockey on the table with my son.
