Balloon C-Strength

Objective

To investigate the strength of a balloon and the conditions that allow them to be punctured and remain inflated.

Difficulty

Procedure: Easy

Concept: Medium

Concept

A balloon is made up of polymer chains that have an elastic quality. At certain points of the balloon, the polymers are not fully stretched and a skewer can penetrate them without bursting the balloon.

Materials

Hypothesis

Make an educated guess regarding what will happen to the material of the balloon. Will it pop? Can it withstand a puncture?

Procedure

Results

What did you observe? What causes the balloon to pop? How many times can you puncture the balloon? Do some research into the properties of the balloon. Explain why your hypothesis was correct or incorrect.

Extension

What variables control the behavior of the balloon in this experiment (e.g. speed, force, etc.)? Why does the oil help the balloon hold together? Does it matter what the balloon is made out of?
