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 far does a balloon car travel?

All cars will use only one 9-inch balloon to power it. Car should be capable of traveling at least 4 Meters. You may not use any of the following: wheels from toy cars, Kinnex, Legos or any items already used for wheels; store bought kits will not be allowed.

What factors will be necessary in order to have a successful balloon car?

This means that there must be an equal and opposite reaction—the air pushes back on the rubber, propelling the balloon forward. This principle is used in real rockets and jets that shoot a high-speed stream of gases out the back of their engines, propelling the vehicle forward.

What makes a toy car go fast?

A car’s speed is often determined by the friction between its wheels and the road. When you drove your toy car over the smooth tile, the wheels were met with little resistance. You can set up a “friction obstacle course” and see which one of your friends can drive the car the fastest over all the tricky surfaces.

What causes a balloon car to move forward?

In the case of the Balloon-Powered Car, the action is the air rushing from the straw and pushing against the air behind the car. The reaction is the air behind the car pushing against the car with the same force causing the forward movement of the car. The moving Balloon-Powered Car is using kinetic energy.

Why does a balloon powered car move?

When the balloon is inflated it stores the compressed air and stretched rubber as potential energy. When you let the air out of the balloon, the potential energy is converted into kinetic energy; this is the energy of motion, which is why the car moves.

What do you call the energy stored in a blown up balloon?

Balloons are elastic and store potential energy when they are filled with air. When the air is released, the potential energy is converted into the energy of motion, which is also known as kinetic energy.

How do you move a toy car with a balloon?

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

How do you make the best balloon car?

Method 3 of 3: Building A Water Bottle Balloon Car

1. Clean out a plastic bottle.
2. Cut two pieces of straws the width as your bottle.
3. Tape the straws to the side of the bottle.
4. Cut two skewers down to make the axels.
5. Slide the skewers into the straws.
6. Make some wheels.
7. Attach the wheels.

Why does a balloon rocket work?

A balloon provides a simple example of how a rocket engine works. The air trapped inside the balloon pushes out the open end, causing the balloon to move forward. The force of the air escaping is the “action”; the movement of the balloon forward is the “reaction” predicted by Newton’s Third Law of Motion.

How does the amount of air in a balloon rocket affect how far it flies?

The bigger balloons move farther because they can push more air. While all of your balloons pushed air out at roughly the same speed, the bigger balloons had more “fuel,” allowing them to exert force for a longer period of time.
