Create balloon rocket racers to see how different sizes of balloons affect the speed and distance traveled. This easy project introduces basic ideas of propulsion and aerodynamics.
If larger balloons are used, then the rocket will travel a greater distance compared to smaller balloons.

Thread the string through a straw and secure it tightly.
Attach one end of the string to a fixed point.
Inflate a balloon and tape it to the straw.
Release the balloon and time how long it takes to travel a distance.
Record the distance traveled and time taken.
Repeat the experiment with different sizes of balloons.
Compare the results of each balloon's performance.
Analyze how balloon size affects speed and distance.
Repeat each test for accuracy.
Summarize findings in a report.
The larger balloons are expected to propel the straws further and faster than smaller balloons due to greater air pressure and volume.

Ensure children do not inhale or swallow balloons.
Use charts to show the results of different balloon sizes.
Include pictures of the experiment setup.
Explain the physics of propulsion simply.
To see how size affects propulsion and travel distance.
Check for leaks or loose tape; ensure the string is taut.
Try different straw lengths or balloon materials.
