SUMMARY

The discussion centers on the creation of a model of Robert Boyle's ever-flowing flask, which is essentially a funnel with a hose designed to recycle liquid. The user proposes a method involving suction to initiate flow, questioning if this could be classified as a Venturi effect. However, the forum moderator clarifies that discussions on perpetual motion machines (PMMs) are prohibited, emphasizing that such concepts fall under pseudoscience and cannot function as intended.

PREREQUISITES
  • Understanding of fluid dynamics principles, particularly the Venturi effect.
  • Familiarity with the concept of perpetual motion machines (PMMs).
  • Basic knowledge of Robert Boyle's contributions to physics and chemistry.
  • Experience with model building and experimental design.
NEXT STEPS
  • Research the principles of the Venturi effect and its applications in fluid mechanics.
  • Study the historical context and scientific principles behind perpetual motion machines.
  • Explore alternative methods for creating self-replenishing models without violating physical laws.
  • Investigate educational resources on fluid dynamics for classroom demonstrations.
USEFUL FOR

Students, educators, and hobbyists interested in physics experiments, particularly those exploring fluid dynamics and the limitations of perpetual motion concepts.

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!
