Saw this at work -- an air bubble trapped right under the water stream

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of an air bubble being trapped under a water stream, with participants sharing their observations and speculations about the underlying physics involved. The scope includes exploratory reasoning and conceptual clarification regarding fluid dynamics and related effects.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about the phenomenon and notes difficulty in recreating it by adjusting water flow.
  • Another participant states that they are not surprised by the occurrence, suggesting it is not particularly rare, but does not provide a detailed physics explanation.
  • A participant mentions having observed similar occurrences frequently, such as with kitchen taps, and speculates that it may relate to the venturi effect, drawing a comparison to a balloon over a nozzle.
  • One participant briefly attributes the phenomenon to surface tension without further elaboration.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the exact explanation for the phenomenon, with multiple viewpoints and hypotheses presented regarding its occurrence.

Contextual Notes

Some participants express uncertainty about the processes involved, and there are references to effects like surface tension and the venturi effect, but these are not fully explored or agreed upon.

Not really sure what's happening here, did a short search online to see if anyone else has documented this before.

(If it's not clear from the photo, there seems to be a air bubble trapped right under the stream)

It sustained itself for a couple minutes, took a short video of it too before it collapsed can't seem to recreate it by adjusting water flow.

I don't find that the least bit surprizing. I can't give you a physics explanation but it is not particularly rare.

likewise have seen it often ... kitchen tap etc

Tho, like phinds, I am not sure of the process, it reminds me of the venturi effect (?) you see with a balloon over a nozzle that air is coming out of
 
Surface tension.
