What does a Gong Sound Like when Hit with a 1189mph Baseball? - Smarter Every Day 267 | Summary and Q&A

TL;DR

A massive air cannon that shoots baseballs faster than the speed of sound is being used to study aerodynamics and ballistics, allowing for precise control of the ball's velocity and timing.

Key Insights

• ⚾ The supersonic baseball cannon is a culmination of the creator's childhood love of baseball, aerodynamics knowledge, and weapons testing experience.
• 🤗 The cannon's ability to control ball velocity and timing opens up possibilities for various future experiments.
• 😜 Non-Newtonian fluids like silly putty can exhibit unexpected behavior when subjected to high-velocity impacts.
• 🚄 High-speed cameras provide valuable data on the behavior of objects in motion, helping understand factors like velocity, deceleration, and impacts.
• 🏛️ Building a mirror setup helps observe the reflection of the baseball and analyze its behavior during flight.
• 💬 The cannon's testing process involves gradually increasing air pressure to characterize its effects on ball velocity.
• ❓ The cannon is being used for scientific purposes rather than being a mere YouTube spectacle.

Questions & Answers

Q: What is the purpose of building a supersonic baseball cannon?

The cannon allows for hands-on learning about the movement of objects at supersonic velocities and facilitates various experiments. It is not merely a YouTube stunt.

Q: What are the key components of the cannon setup?

The setup includes a giant air cannon, high-speed cameras, a team to manage the cameras, documenting the process, and suggestions from patrons on interesting things to test.

Q: How does silly putty behave when hit by a supersonic baseball?

Silly putty, being a non-Newtonian fluid, acts like a solid when hit rapidly. It absorbs energy from the baseball, possibly shattering like glass.

Q: What happens when a supersonic baseball hits a mirror?

The high-speed cameras capture the impact, and the baseball redirects slightly, altering its trajectory. It also causes a shock wave, flattening when it hits the front of the mirror.

Summary & Key Takeaways

• Smarter Every Day has built a giant air cannon to shoot baseballs faster than the speed of sound, combining childhood love of baseball with aerodynamic studies.

• The cannon is being characterized to understand how the amount of air pressure correlates with the ball's velocity and deceleration.

• High-speed cameras provide slow-motion footage to analyze times, distances, and velocities, allowing for deeper insights about the ball's behavior.
