What to do
- Tie one end of the string to a chair, door knob, or other support.
- Put the other end of the string through the straw.
- Pull the string tight and tie it to another support in the room.
- Blow up the balloon (but don't tie it.)
- Let go and watch the rocket fly!

Likewise, people ask, what materials do you need to make a balloon rocket?
Materials:
- Rubber Balloons.
- Binder clip.
- String or Thin Rope.
- Straws.
- Tape.
- Cloth Tape Measure.
- Two Posts (At least three feet tall and fifteen feet apart)
- Paper.
Also, what are all the forces acting on a balloon rocket? 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.
Herein, how do you make a balloon rocket car?
Procedure
- Put your car down on a flat surface and give it a good push.
- Tape the neck of the balloon around one end of the other straw.
- Cut a small hole in the top of the water bottle, just big enough to push the straw through.
- Push the free end of the straw through the hole and out the mouth of the bottle.
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.

Would a balloon rocket work in space?
How far did your balloon rocket travel? Even though you did not fill the balloon with rocket fuel, it was able to blast off just like a space shuttle. In fact, the balloon is so light that all it needs is a jet of air to create enough thrust to get it to move through space.
What materials are used in a two stage rocket?
A rocket must withstand the strong forces during launch and be as light as possible. For the main frame most rockets use aerospace grade aluminum or titanium since both metals are very strong but light weight. Future rocket designs are even looking into using carbon composite structures.
