Discussion Overview

The discussion explores the feasibility of generating force through breathing into a tube, particularly in the context of creating a seal and its potential applications, such as in devices like spray guns. The conversation touches on both theoretical and practical aspects of this concept.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions the amount of force or air pressure that could be generated through this method.
  • Another participant references an external source about aspirators, suggesting a connection to the topic.
  • A different participant identifies the concept as similar to a "venturi pump," indicating a known principle in fluid dynamics.
  • One participant shares an example of a device that uses breath to create a spray effect, illustrating a practical application of the concept.
  • Another participant expresses skepticism about the effectiveness of using lungs to perform larger tasks, such as emptying a fish pond, indicating limitations of the method.

Areas of Agreement / Disagreement

Participants have not reached a consensus; there are varying opinions on the effectiveness and practicality of using breathing through a tube to generate force, with some suggesting potential applications and others highlighting limitations.

Contextual Notes

The discussion does not resolve the assumptions regarding the efficiency of air pressure generation through human breath and its dependence on specific applications or designs.

How much force(air pressure would the process in this video take?



Could it be produced or magnified to work using breathing through a tube? To create the seal?

Depends what you want to do. I've seen a device that converts a felt tip pen into a crude spray gun by blowing through a tube at right angles to the pen nib. It draws the ink out of the pen and blows it onto the paper.

You would have a hard time emptying a fish pond using just your lungs to blow down a pipe.
