Bowl Riddle Solution (Plus 2 BONUS riddles) ft. Kurt Hugo Schneider part 2/3

## TL;DR

Kurt Hugo Schneider attempts riddles with Physics Girl, including finding a solution to a ball in a bowl riddle and explaining the phenomena of sound cancellation.

## Key Insights

• 🥣 Using a cup to displace water in a bowl is a clever solution to the ball in a bowl riddle.
• 👋 Sound cancellation occurs when two waves with the same amplitude and wavelength, but exactly out of phase, cancel each other out.
• 🧘 Phase problems in audio recording can occur when positioning microphones incorrectly, resulting in poor audio quality.

## Transcript

Thanks to WIX for supporting PBS Digital Studios. Hey, it's Diana, and you're watching Physics Girl, back with video 2 of Riddles with Legendary Music Producer, Kurt Hugo Schneider. This is one of my favorite series, because I found people that like riddles almost as much as I do and who think I'm nice enough to make them look good on camera attem... Read More

### Q: How did Kurt eventually solve the ball in a bowl riddle?

Kurt used a cup to displace the water in the bowl, causing the ball to touch the bottom without directly touching it.

### Q: What is sound cancellation?

Sound cancellation occurs when two waves with the same amplitude and wavelength, but exactly out of phase, overlap and cancel each other out.

### Q: What are some potential phase problems in audio recording?

Positioning microphones incorrectly when recording an instrument, such as a guitar, with two mics can lead to phase problems and affect the quality of the audio.

### Q: What is the next riddle that viewers must wait for the answer on?

Viewers must wait for the next video to find out whether the two sides of a broom, cut at the point of balance, are of the same weight or if one side is heavier.

## Summary & Key Takeaways

• Kurt Hugo Schneider attempts to solve a riddle involving getting a ball to touch the bottom of a bowl without directly touching it, eventually using a cup to displace the water and make the ball touch the bottom.

• The video also explores the concept of sound cancellation, where two waves with the same amplitude and wavelength, but exactly out of phase, can cancel each other out.

• Kurt and Physics Girl discuss the importance of phase in audio recording and potential phase problems when using multiple microphones.
