🎈 CD Balloon Hovercraft Introduction

In this video, Rachel from the Questacon Science Squad introduces a fun and educational project: creating a CD balloon hovercraft. The necessary materials are listed, including a balloon, a pop-top lid, craft glue, and an old CD. The process begins with applying glue around the CD's center, attaching the pop-top lid, and allowing it to dry for approximately 20 to 30 minutes. Rachel shares a personal anecdote about using a cherished Kamahl record for her demonstration, emphasizing the project's adaptability to any CD or record.

Keywords

💡CD balloon hovercraft

A CD balloon hovercraft is a fun and educational project that demonstrates the principles of physics through a hands-on activity. It is a device that uses the air pressure difference created by a balloon to 'hover' above a surface, typically a CD in this context. In the script, Rachel from the Questacon Science Squad guides viewers through the process of creating their own CD balloon hovercraft, which is central to the video's theme of science education and experimentation.

💡Questacon Science Squad

The Questacon Science Squad is a group that appears to be dedicated to promoting science education and engaging the public in scientific activities. In the script, Rachel introduces herself as a member of this squad, indicating that the video is part of a series or initiative by Questacon to spread scientific knowledge in an accessible and entertaining way.

💡Craft glue

Craft glue is an adhesive substance commonly used in various DIY and craft projects. It is typically easy to apply and dries to hold materials together. In the context of the video, craft glue is one of the essential materials needed to attach the pop-top lid to the CD, which is a crucial step in the construction of the CD balloon hovercraft.

💡Pop-top lid

A pop-top lid is a type of container closure that can be opened with a popping sound, often associated with beverage cans. In the script, the pop-top lid is repurposed as a key component of the hovercraft, serving as the base that the balloon's air will push against to create lift.

💡Old CD

An old CD refers to a compact disc that is no longer in use for its original purpose, such as playing music. In the video, the old CD is given a new life as the platform for the hovercraft. This not only demonstrates creativity but also promotes recycling and reusing materials in a novel way.

💡Drying time

Drying time refers to the duration it takes for a substance, such as craft glue, to fully set and harden. In the script, Rachel mentions that the glue will take about 20 minutes to half an hour to dry, which is an important detail for viewers to know in order to plan their project timeline and ensure the hovercraft is constructed properly.

💡Kamahl record

The Kamahl record is a specific example of an old CD used in the demonstration. It adds a personal touch to the script and shows that any CD, regardless of its original content, can be used for this project. The mention of the record also provides a humorous anecdote, making the video more engaging.

💡Balloon

A balloon is an inflatable bag made of a stretchable material, often used for decoration or play. In the context of the hovercraft, the balloon is inflated with air and then stretched over the pop-top lid, creating a seal that allows the air pressure inside to push against the CD and create lift.

💡Pinch

To pinch something means to hold it tightly between one's thumb and fingers, preventing air or liquid from passing through. In the script, Rachel instructs viewers to pinch the neck of the balloon to prevent air from escaping, which is vital for maintaining the air pressure needed for the hovercraft to function.

💡Hover

To hover means to float or be suspended in the air without moving forward or backward. In the video, the term is used to describe the expected result of the CD balloon hovercraft project, where the CD should levitate slightly above the surface due to the air pressure created by the balloon.

💡Questacon website

The Questacon website is mentioned as a resource for viewers who want to learn more about creating a CD or record balloon hovercraft. It implies that there may be additional instructions, materials, or related projects available online, extending the educational experience beyond the video itself.

(Sound of bubbles popping)

Hi everyone, my name’s Rachel, I’m from the Questacon Science Squad,

and today we’re going to show you how to make a CD balloon hovercraft

You need:

a balloon

a pop-top lid

some craft glue and

an old CD you’re not listening to any more

Next, glue around the middle of the CD

Put the pop-top lid onto the glue, and, that’s going

to take about 20 minutes to half an hour to dry.

So here’s one I prepared earlier.

20 years earlier in fact. This is my Kamahl record and I love it.

OK, next step, blow up your balloon.

Pinch the neck so no air escapes, very important,

and stretch the top of your balloon over the pop-top lid

making sure the pop-top lid is fully open

Let’s see if our Kamahl record will hover.

Here we go. Ready, set, go.

Whoops, there we go

If you want to make your very own CD or record

balloon hovercraft, visit our Questacon website.

See you next time
