This simple hovercraft project uses a CD and a balloon to demonstrate the principles of air pressure and lift. It's a fun and interactive way to learn about basic physics!
If air is forced beneath the CD by the balloon, then the hovercraft will lift and glide smoothly over a flat surface.

Take the CD and place the bottle cap in the center.
Secure the bottle cap with tape to the CD.
Inflate the balloon and pinch the opening.
Place the balloon over the bottle cap and release.
Observe the CD hover and glide over the surface.
Experiment with different surfaces to see how they affect the hovercraft's movement.
Discuss the science of lift and air pressure involved.
Consider designs to improve the hovercraft's performance.
The hovercraft will lift off the surface and glide, demonstrating how air pressure can create lift and reduce friction.

Be careful with scissors when preparing the materials.
Demonstrate how the hovercraft works during your presentation.
Explain the science behind lift and air pressure.
Involve the audience by letting them try the hovercraft.
Use visuals to illustrate concepts of physics.
Air from the balloon creates pressure under the CD, generating lift.
Yes, experiment with different hovercraft designs and materials.
Check for leaks in the balloon or improper sealing around the cap.
