Balloon Rockets

Balloon rocket
Hypothesis:
It will fly like a rocket


Materials
balloon, tape, 2 stable objects, string
Observation (What happened)
The balloon went flying across the string like a rocket just like my prediction.



Conclusion (Why I think it happened)
The air from the back of the balloon pushes against the stable objects just like flames pushes against the ground on a rocket.
