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 do you make a successful balloon car?

3 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.

How do you reduce friction on a balloon car?

Placing down smooth straws with the ability to roll along the ground will create much less friction and allow the balloon car to travel farther. Adding “sleigh rails” to the bottom of the box will allow the balloon car to travel farther also.

What forces are acting on a balloon car?

What forces are acting on the balloon rocket car? There are two main forces acting on the balloon rocket car: Friction and Air resistance. The friction force is the resistance between two objects sliding against each other.

What is the science behind balloon cars?

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. This is the energy you see when the car is propelled forward.

Why is my balloon powered car not moving?

There are many reasons that cause your own car not to get in motion, which includes: particularly if its axles are not parallel or the wheels wobble, your balloon may not be thoroughly attached to the straw, the balloon may not sat on the car when inflated instead on the floor, too much friction can cause the wheels to …

What are the best materials for a balloon powered car?


  • Plastic bottle.
  • Four plastic bottle caps.
  • Wooden skewer.
  • Two straws.
  • Balloon.
  • Tape.
  • Scissors or sharp knife (Have an adult use or supervise your use of this tool.)
  • An adult helper.

Why is my balloon car going in circles?

Your balloon car uses jet power to move. The stored air in the balloon pushes through the straw, creating thrust—the force that pushes the car forward. So when air from the balloon moves in one direction, it pushes the car in the opposite direction.

How do you make a rubber band car go farther?

Turn the axle several times. You’ve given the rubber band potential (stored) energy. When it unwinds, this potential energy is transformed into kinetic (motion) energy, and the axle spins. The more you wind the rubber band, the more energy is available for your car’s wheels—and the farther and faster your car goes.

Can a Balloon car travel the longest distance?

To build a Balloon Rocket Car that can extract the most energy out of the inflated balloon and make the vehicle travel the longest distance. The thrust of a jet engine is similar to the thrust produced in the balloon rocket car.

How to make a Balloon car out of cardboard?

Here are the simple step-by-step instructions to make a balloon car out of cardboard: Step-1: Cut a 3 by 6-inch (7.62 by 15.24 centimetre) rectangle out of cardboard. Step-2: Cut two 3-inch (7.62 centimetre) pieces from a straw. Step-3: Tape the straws to the cardboard.

How do you run a balloon rocket car?

Line the Rocket car up on the starting line and when the track is clear release the balloon. Record the distance the car went. Each team is allowed to change the car once (adjust wheels and/or nozzle) but the team may run the car on the track as many times as they feel necessary.

What are the rules for a Balloon car?

A BALLOON CAR is any vehicle which travels on the course using one or two officially supplied balloons for power. The simple rules, including the judging categories, and entry form are shown below. Simply fill out the entry form and make arrangements to pick up your official balloons before the deadline of December 15th.
