# Does the shape of the balloon affect how far or fast the rocket travels?

## Does the shape of the balloon affect how far or fast the rocket travels?

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.

## How do you make a balloon race?

DIRECTIONS:

1. Build the track by attaching a string to the wall with a thumbtack or tape. Hold the other end of the string and walk to the far side of the room.
2. Attach the straw and balloon to your racer.
3. Thread the end of the string through the straw.
4. After threading the string, inflate the balloon and, 3,2,1, LET GO!

What direction do balloons move?

opposite direction
The balloon always moves in the opposite direction from the jet of air. 2. The more compressed air there is in the balloon, the more force it will have and the faster it will move. If you decrease the number of pumps (lower the air pressure), the balloon has less force and will go slower.

### What materials are used in the two stage rocket?

MATERIALS and TOOLS:

• 2 long party balloons (round balloon will not work)
• Nylon monofilament fishing line (any weight)
• 2 Plastic straws (milkshake size, non-bendable)
• Styrofoam cup.
• Scissors.

### What makes a balloon rocket move?

The escaping air exerts a force on the balloon itself. The balloon pushes back in a manner described by Newton’s Third Law of Motion. That opposing force—called thrust, in this case—propels the rocket forward.

What makes the balloon expand?

Air molecules collide into the balloon with the same energy inside and outside the balloon. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

## What made the balloon move?

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.

## What made the balloon rocket move?

When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. The escaping air exerts a force on the balloon itself. That opposing force—called thrust, in this case—propels the rocket forward.

What happens when you add cargo to the balloon rocket?

As the gases escape from the balloon, they exert a force on the outside air, which in turn exerts an opposing force and pushes the balloon forward. Increasing the pressure of the gas inside the balloon will make the balloon move faster along the track. The increased weight from the cargo slows down the balloon rocket.

### How to make a balloon rocket science experiment?

Instructions 1 Position two objects of the same height (I’m using chairs) about 10 feet apart and grab a piece of string. 2 Tie one end of the string to one of the objects. 3 Next, get a straight plastic drinking straw. 4 Place two pieces of tape on the straw. 5 Thread the string through the straw

### 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.

How do you make a rocket out of string?

Position two objects of the same height (I’m using chairs) about 10 feet apart and grab a piece of string. Tie one end of the string to one of the objects. Make sure it is securely fashioned. Next, get a straight plastic drinking straw.

## How can you increase the speed of a balloon?

Here, air resistance is nothing but the drag. By reducing the air resistance, you are letting the force to escape in lesser amounts and increasing the speed of travel at the same time. 3) Change the nozzle of the balloon: Change the opening of the balloon by attaching some other appliances like ready-made nozzles, pipes, etc.
