How to Build a Toy Hovercraft

Looking for a fun craft project for you and the kids (or just you and your friends if you like DIY projects)? Then this one is for you: how to build a toy hovercraft. All you need is:

  • CD
  • Bottle cap
  • Thumbtack
  • Hot glue gun

And, if you’re like us, you probably have all of this sitting around the house — including that old CD you got from an ex who thought it would be romantic to put a bunch of songs on a CD and give it to you as a “gift” rather than buy you an MP3 player or something really useful.

(Issues, much? Anyway…)

The video comes courtesy of Daniel Ehlers, who has supplied FTK with a number of cool Life Hack videos. As he explains on his YouTube page:

Hovercraft use blowers to produce a large volume of air below the hull 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.

For stability reasons, the air is typically blown through slots or holes around the outside of a disk or oval shaped platform, giving most hovercraft a characteristic rounded-rectangle shape.

Check out how it works, how quick and easy it is to put one of these together, and imagine all the fun you and your friends can have with this little project.
