- A balloon
- A sports cap
- Blu Tack
- A blank CD or DVD
- And some help from a grown-up!
Attach the balloon to the top of the sports cap
Make a sausage-shape out of the Blu Tack by rolling it between your hands. Now wrap it around the bottom of the sports cap.
Attach the sports cap to the CD by placing it over the hole in the middle, and pressing the Blu Tack down with your fingers
Inflate the balloon by blowing through the hole in the CD. Close the sports cap to keep the air in!
Place your hovercraft down on a flat surface. When you’re ready, open the sports cap and give it a push! Try it out on some different surfaces – or make a few and have a race with your mates!
