Hovercraft Havoc: Glide Into Fun!

Get ready to defy friction and explore the science of air pressure with your very own balloon

powered hovercraft! Using simple materials, you’ll create a high-speed gadget that glides across smooth surfaces. Race your patrol, tweak your design, and discover the engineering magic behind the hovercraft. Let’s get rolling (or should we say hovering)!

Safety Tips

• Balloon Safety: Balloons contain latex—check for participant allergies.
• Hot Glue Gun: Use with caution and under supervision. Review hot glue gun safety tips if needed.
• Ensure the working area is clutter-free and well-ventilated.

Before you begin

• Ensure all Scouts and adults understand the safety guidelines for this activity.
• Gather adult helpers to supervise where necessary.
• Set up a smooth, clean surface to work on and ensure everyone is equipped with the required materials.
• Check for balloon allergies among participants, and ensure a well-ventilated area.

The Activity

Step 1: Prepare Your Materials

• Roll blu-tack into a snake shape, long enough to wrap around the base of the pop-top lid.
• Stick the pop-top lid securely to the centre of the CD. Ensure the lid is closed.

Step 2: Attach the Balloon

• Inflate the balloon and carefully stretch its opening over the pop-top lid. Ensure the lid is closed to prevent air from escaping.

Step 3: Test the Hovercraft

• Place the CD on a smooth surface.
• Open the pop-top lid to release air and gently push the hovercraft. Watch it glide across the surface!

Step 4: Experiment and Play

• Race your hovercrafts against others in your Patrol.
• Try adjusting factors like the size of the balloon or base to see how it affects movement.
