CD Hovercraft

Demonstrate a hovercraft with very common supplies.

Build Time:

  • Approximately 10 minutes

Skills Needed:

  • Ability to use a hot glue gun
  • Ability to stretch a balloon tip over a nozzle (harder than it sounds)



Step-by-step guide

  1. Begin by applying glue to the rim of the bottom of the push pull cap.
  2. Press the cap on top of the center of the CD.
  3. Apply more glue at the seam of the cap and the CD to ensure a good seal.
  4. Wait a few moments for the glue to cool.
  5. Now stretch the balloon over the push pull cap.
  6. Inflate the balloon by blowing on the underside of the CD and pinch the balloon to keep the air from leaking.
  7. You are ready to hovercraft!
