SUMMARY

The snapping sound produced when a towel is snapped is identified as a small-scale sonic boom. This phenomenon occurs due to the rapid movement of the towel, creating a pressure wave similar to that generated by a whip. The discussion highlights the interesting nature of this sound, comparing it to the mechanics of a whip. Participants express curiosity about the mechanics behind the sound and share anecdotes related to the topic.

PREREQUISITES
  • Understanding of basic physics principles, particularly sound waves
  • Familiarity with the concept of sonic booms
  • Knowledge of fluid dynamics related to air pressure
  • Awareness of the mechanics of whip dynamics
NEXT STEPS
  • Research the physics of sound waves and their propagation
  • Explore the mechanics of sonic booms in various contexts
  • Investigate the dynamics of whip cracking and its comparison to towel snapping
  • Learn about fluid dynamics and air pressure effects in everyday objects
USEFUL FOR

Physics enthusiasts, educators, and anyone interested in the science behind everyday phenomena such as sound production and fluid dynamics.

What causes the snapping sound when a towel is snapped? I'm hoping that no one here has seen this before. I already know the answer.
 
Physics news on Phys.org
Then why ask? Is this just some stupid way of showing off?

(And why in the world should we believe you "already know" just because you say so?)
 
I didn't figure out the problem, someone just told it to me along with the answer so I'm not showing off. The reason I posted this question is that the answer turns out to be very interesting. If you want, I'll private message you the answer and you can tell me if you think it's worth posting.

Correct, as you already know. The version I heard involved a whip. I thought changing it to a towel would make it tougher. Oh well.
 
Okay, this thread wasn't too productuve. Anyone know who to make one of those "death whip towels"? Ouch!
