How do water behave with no gravity - video

Click For Summary

Discussion Overview

The discussion revolves around the behavior of water in a microgravity environment, as illustrated by a video demonstration. Participants share their reactions to the visuals and explore related concepts, including standing waves and spherical harmonics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants express excitement about the visual demonstrations of water behavior in microgravity, particularly the effervescent demo.
  • One participant suggests that the demonstrations can be used to study spherical harmonics of Bessel functions and the evolution of planetoids.
  • Another participant shares a link to a collection of videos related to the topic, noting the absence of these videos on YouTube.
  • There is a disagreement regarding the interpretation of a 2D standing wave demonstration, with one participant asserting it is a demonstration of standing waves, while another contests this claim.
  • A participant argues that the observed shapes in the demonstration are due to the vibration of rice mapping the nodes of the standing wave.

Areas of Agreement / Disagreement

Participants generally express enthusiasm for the video content, but there is disagreement regarding the interpretation of the standing wave demonstration, indicating multiple competing views on this aspect.

Contextual Notes

The discussion includes varying interpretations of the demonstrations and the underlying physics concepts, with some assumptions about the nature of the demonstrations remaining unresolved.

found this, and thought you guys will enjoy it too =)
so here you go:

Cool!
 
Wow, I want a Sphere of Water to play with!

I'd like a pair of them. Maybe it's cause I'm a guy.
 
This is so cool, the Effervescent demo is great!

They're obviously real...
 
A great way to study the spherical harmonics of Bessel functions, or the evolution of planetoids.
 
glad you like it, i thought you guy would appreciate it.
i also found a 2D standing wave demonstration:
The movie

and have a look at this site:
over here
 
That is way cool.

The whole set can be found http://spaceflight.nasa.gov/station/crew/exp6/spacechronicles_videos.html. I didn't see them on youtube.

i don't really agree that that is demonstration of a standing wave

sure it is, the rice is vibrated off the parts with amplitude to the nodes, and that's why you get these shapes... it's mapping the nodes.
