Your design will be most efficient if the straw is pointed straight back and not downward or to the side. The more you inflate the balloon the more potential energy it stores, which in turn is converted to more kinetic energy, according to the law of conservation of energy—so the car will go faster.

What makes a good balloon car?
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.
How do you make a balloon car go straight?
Put the long end of a flexible straw into a balloon. Poke two holes in the bottle's sides, on the part of the bottle that will be the bottom of the car. Make the holes directly across from each other so the axle goes straight across.
How do the wheels affect the distance and speed of the balloon racer?
IF THE WHEELS ARE BIGGER, THEN THE CAR WIIL MOVE FASTER AND TRAVEL FARTHER. IF THE WHEEL SIZE IS LARGER, THEN THE CAR WILL TRAVEL FARTHER.
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.
What happens if you adjust the direction the straw is aimed?
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.
How does gravity affect a balloon car?
If you set up an acceleration (which remember has the same effect as gravity), the balloon is going to move opposite to this pseudo-gravitational force. ... In the car, it's the air molecules that are actually getting pulled and pushed around by gravity as the result of the accelerating frame.
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 ...
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 happens if you inflate the balloon more?
As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands... ... If you put in too much helium, and the pressure inside the balloon exceeds the atmospheric pressure on the outside of the balloon, the balloon will burst.
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 physics behind a balloon car?
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.
