Experiment conducted by Team Scream: Allie, Rachel, and Cannan.
Use of a vacuum chamber to simulate space conditions.
Experiment Setup
Vacuum Chamber: Goal to reach a full vacuum, 29.92 inches of mercury.
Sound Measurement: Initial and full vacuum sound levels measured.
Use of a whoopee cushion and inner tube as experimental tools.
Findings
Vacuum Conditions:
At full vacuum, the sound of the scream becomes inaudible.
The only noise detected was from the motor vibrations where it contacted the chamber wall.
Conclusion from Initial Test:
Under a vacuum, there is no medium to carry sound, confirming the myth in a traditional sense.
Additional Scenario
Last Breath Test:
Simulating an astronaut expelled into space holding a breath.
Inner tube used to mimic the lungful of air.
Results:
Sound was faint but detectable when the air was released, indicating that the air could carry sound momentarily.
Conclusion
Final Myth Evaluation:
Myth initially confirmed: no air equals no scream.
Exception: If within a close distance (e.g., a foot) while holding breath, sound can be transmitted.
Final Verdict: Myth Busted due to this exception scenario.
Key Takeaways
Sound requires a medium to travel.
In a vacuum, sounds typically cannot be heard unless there is a medium present, even briefly.
Educational Insight: The demonstration provided an engaging method to understand the mechanics of sound propagation in different environments (e.g., space).
Humorous Elements
Frequent use of humorous and light-hearted elements like the whoopee cushion to engage the audience.
Use of sound effects and playful commentary to keep the experiment lively and entertaining.
