CD Hovercraft

Project Story

What I made
About 5 years ago, my sister and I made this CD Hovercraft as a fun science project. We wanted to learn how air pressure can reduce friction and help objects move easily.

Why I made it
This project showed us that simple household items can be used to understand real science concepts.

What I learned
Air pressure can create lift. Reducing friction helps objects move more easily. Science can be learned through simple experiments. Engineering projects can be made from recycled materials.

Materials & Components

Old CD Balloon Plastic bottle cap with pop-up valve Glue gun or strong glue Flat table or floor

How to Make It

Step 1 Take an old CD and make sure the center hole is clean. Step 2 Glue the bottle cap over the center hole of the CD. Step 3 Allow the glue to dry completely. Step 4 Inflate the balloon and twist its neck to stop the air from escaping. Step 5 Attach the balloon to the bottle cap. Step 6 Place the hovercraft on a smooth flat surface. Step 7 Open the bottle cap valve and release the air. Step 8 Watch the hovercraft glide across the surface.
