Balloon Hovercraft

You don't need high-tech gadgets to make your own hovercraft! This balloon-powered toy is easy to make with household materials and is a ton of fun to send zooming around! We had so much fun passing the hovercraft across a long table. A light push sends it gliding along in a straight path. And, the balloon had enough air in it for a few pushes, which means you can involve a few friends. Keep blowing the balloon up for more and more fun!

Trade your hovercraft for a space shuttle with KiwiCo's Astronaut Starter Kit! This project comes with everything you need to construct a shuttle, paint a set of model planets, and more!

Step-by-step tutorial

  • Step 1

    Gather your materials!

  • Step 2

    This step will require some adult help!
    Open the bottle cap. Glue the mouth of the bottle cap onto the middle of the CD. If you use hot glue, ask an adult to help you out. Make sure there' glue all the way around the cap. You don't want to have any gaps where air could leak out.

  • Step 3

    Once the glue has dried, stretch the end of the balloon over the bottle cap.

    Inflate the balloon by blowing into the hole on the other side of the CD. Quickly close the nozzle once you are done.

  • Tip

    If you have trouble with this step, try out step 5 instead. Otherwise, skip to step 6.

  • Step 5

    Take off the balloon and close the cap nozzle. Inflate the balloon to your desired size, then pinch the base about 1 inch (2.5 cm)above the tip and stretch it over the bottle cap.

  • Step 6

    Set the hovercraft down on a flat, smooth surface. Twist or pull the nozzle cap open without removing the balloon. As air flows out of the balloon, it'll start to hover! Try giving it a push and watch it slide around.
    This activity is a great way for kids to experiment with friction. As long as the balloon is still filled with air, you can easily push the hovercraft across a smooth tabletop. But as soon as the air runs out, it quickly comes to a stop. The cushion of air reduces the friction between the CD and the tabletop, allowing your hovercraft to fly, just like the puck on an air hockey table.
