Discussion Overview

The discussion revolves around the feasibility of creating a model of Robert Boyle's ever flowing flask, a device that is conceptually linked to perpetual motion. Participants explore the mechanics of the flask, including the potential use of suction to initiate flow, and the implications of such a design.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant proposes using suction at the end of the hose to initiate the flow of liquid into the funnel, questioning if this could be considered a type of venturi effect.
  • Another participant points out that Boyle's flask represents a perpetual motion machine, suggesting that it cannot function as intended.
  • A different participant acknowledges the impossibility of the device but expresses interest in the idea of providing an initial push to start the flow, indicating a sense of curiosity despite the theoretical limitations.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of the ever flowing flask, with some acknowledging its classification as a perpetual motion machine while others explore potential methods to initiate flow.

Contextual Notes

The discussion touches on concepts related to fluid dynamics and the principles of perpetual motion, but lacks a resolution on the viability of the proposed methods.

Hello everybody! I am new here and have not looked around much on the forum for an answer to my question, so sorry if this should be obvious to me but:
I want to create a model of the Robert Boyle ever flowing flask for my class.

For those of you who do not know what this is, it is basically a funnel with a hose that goes from the bottom, around, and back into the top of the funnel to replenish the supply... hence... ever flowing.

Of all the videos on Youtube i have never seen one work well but i have recently come up with an idea. What if you put your mouth on the end of the hose and suck the water/soda/beer through until it reaches the end and flows into the funnel? Would this be a type of venturi and would it work? I am planning on tying this but would like an answer is someone has one.

Thanks for any suggestions or information you guys can give me!

You do know Boyle's flask is a perpetual machine, so it can't work, right?
 
I know that, but it seems like there would there would be more potential helping it start, instead of letting the liquid simply balance itself. I know i am grasping at straws but it seems so entertaining!
