## What can I use as wheels for a balloon powered car?

Use circles are used as wheels for the balloon powered car. Step-9: Now you are ready with your own balloon car made out of cardboard! Inflate the balloon using the straw and pinch the straw shut so that the air doesn’t escape. Place the car on a smooth, flat surface and let go of the straw and watch the car go!

## How do you make balloon powered toys?

Step 1: Cut the straw in half. Insert a straw into the neck of the balloon and secure with a rubber band. Step 2: Tape the balloon and straw to the top of the toy car, with the straw pointing toward the back of the car. Step 3: Blow through the straw to inflate the balloon.

What happens if you inflate the balloon more?

When you inflate a balloon, you’re actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands… As you go higher into the atmosphere, the air becomes thinner, and the atmospheric pressure drops.

How far can a balloon car travel?

All cars should travel in a straight line. All cars will use only one 9-inch balloon to power it. Car should be capable of traveling at least 4 Meters.

### How can I make my balloon car stronger?

How to Make a Balloon Car Go Faster

1. Reduce Weight. Examine your car carefully for any opportunity to shed as much weight as possible.
2. Minimize Drag. Drag, or air resistance, is important even at low speeds because the balloon car is so lightweight.
3. Cut the Friction.
4. Improve the Nozzle.

### How do you move a toy car with a balloon?

When you tape the balloon to a straw and attach it to the body of your car, however, you can control the direction of the escaping air. When the end of the straw is aimed backward, the air pushes your car forward, as described by Newton’s third law of motion.

What do you feel as you press the balloon?

You probably feel the air pressing against the wall of the balloon with even greater force. By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases.

Is it illegal to let go of balloons?

In New South Wales, it is an offence to let go 20 or more helium balloons at once, with a greater penalty for the release of more than 100 balloons. If you are releasing fewer than 20 balloons at around the same time, they must not have any attachments (like string or plastic discs).

#### Why does my balloon car not move?

Some of the things that slow balloon cars down, that you have to overcome, are their own weight, air resistance, friction, and inefficient use of the air escaping the balloon. Reducing weight, minimizing drag, cutting friction and improving nozzle air flow will all help make your balloon car go faster.

#### What happened as you press the balloon and release it?

When we inflate a balloon, we fill it with a pressurized gas (air). When we let go of the end, the air rushes out and pushes against the air around the balloon to move it in the opposite direction. Newton describes this effect in his Third Law of Motion: for every action, there is always an equal and opposite reaction.

What do you need to make a balloon buggy?

Using the metal rule and felt tip pen mark out a rectangle 10cm (W) x 16.5cm (L) on corrugated plastic sheet. Cut out the rectangle with the cutting knife and rule to make the buggy base. Measure, mark and cut four 4cm lengths of straw using the rule, pen and scissors.

How to make an air powered balloon car?

How to make an air powered balloon car. All you need are bottle tops, 2 pens, a hammer, a nail, some carboard and a balloon.

## How do you make a buggy out of straws?

TIP— Use a strip of masking tape to hold the straws in place while gluing. Mark two lines 2.5 cm long on the buggy base 2 cm from one end. Run glue along each line as shown, and then attach the axle before the glue hardens. The straws should overlap each edge by roughly 0.5cm, so the wheels can’t touch the base edge.

## How do you make a balloon out of cardboard?

The balloon should be resting on top of the cardboard and the straw hanging over one of the ends. Tape the straw securely to the cardboard. It’s okay if the straw is hanging over the edge of the car. If it is touching the ground, trim it down.
