How to Make a Mini Hovercraft With Balloon Power

The hovercraft is a land and sea vehicle known for its ability to hover on a cushion of air. This air is pumped through heavy-duty fans on a hovercraft, but you can duplicate the effect using a few simple household materials, such as an old CD, some glue and a balloon.

Things You'll Need

Old CD
Pop-top from a water bottle
Glue
Balloon
Elastic band

Instructions

- 1
  Place the CD on your work surface. Dab some glue around the hole in the center.
- 2
  Place the pop-top on the center of the hole, over the glue. Glue the piece into place with some extra glue to create an air-tight seal. Leave the glue to dry overnight.
- 3
  Push the pop-top to the down position.
- 4
  Wrap the mouth of the balloon over the pop top.
- 5
  Wrap the elastic band around the mouth of the balloon to make this seal also airtight.
- 6
  Grip the pop-top through the balloon and elastic band and pull up. Blow some air into the balloon through the bottom of the CD and through the pop-top to inflate the balloon. When it is full, push the pop-top down through the balloon to seal off the air.
- 7
  Pull up the pop-top to start releasing the air and pushing the hovercraft up. The hovercraft is now hovering, and you can push it to make the vehicle float.
