Physics Demonstration: Balloon Rocket
Objective: Describe the action and reaction forces.
Materials:
balloons straws string tape scissors
Precaution: Be careful in using sharp objects like scissors.
Procedure:
Note: Each step must be properly documented through a drawing, a photo, or a video.
Tie one end of a string to a chair, doorknob, or other support.
Put the other end of the string through a straw. Then pull the string tight, and tie it to another support in the room.
Blow up the balloon, and pinch the end of the balloon to keep the air inside. Do not tie the balloon.
Have a partner tape the balloon to the straw so that the opening of the balloon is horizontal with the ground, while you keep the air pinched inside the balloon. See the figure below.
my advice, if you don't like doing these kinds of activities you should use you imagination in answering the questions. the procedures are already stated so it should be easy to imagine what happens to the balloon rocket :)
