SUMMARY

This discussion centers on the functionality of drinking straws in different environments, particularly in a vacuum. The mechanics of a straw rely on atmospheric pressure, which forces liquid up when the pressure inside the straw is reduced by sucking. The participants humorously speculate about the implications of using a straw in extreme conditions, such as a black hole or a vacuum, highlighting the fundamental physics principles involved. The conversation blends scientific inquiry with lighthearted banter about the absurdity of the scenarios presented.

PREREQUISITES
  • Understanding of atmospheric pressure and its effects on liquids
  • Basic knowledge of fluid dynamics
  • Familiarity with vacuum concepts in physics
  • Awareness of black hole and wormhole theories
NEXT STEPS
  • Research the principles of fluid dynamics in varying pressure environments
  • Explore the physics of black holes and their effects on matter
  • Learn about vacuum systems and their applications in scientific experiments
  • Investigate the role of atmospheric pressure in everyday phenomena
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in the principles of fluid mechanics and the effects of pressure on liquids.

So I have this inside joke about how I like wasting my professors time by going to their office hours and asking them how a straw works (no, I haven't been kicked out of my grad program yet). For a second, it kind of perplexed me how a drinking straw worked. Instead of wasting my time thinking about it being apart of the instant gratification culture, i looked it up on wikipedia. Of course, the outside pressure acting on the liquid forces it down and then back up the straw when you lower the pressure in the straw by sucking on it. That made me think then... straws must not work in vacuum! Eh Eh?? That was my physics thought for the month.

FAR OUT man! I wonder how would a straw work in a black hole inside a wormhole between two stars spinning inside my head work monday.:bugeye:

Does it have coke or sprite in it?

It's all about the black hole effect.
