Discussion Overview

The discussion revolves around the operation of mist makers, specifically focusing on the mechanisms by which they create mist. Participants explore various theories and explanations related to the technology, including ultrasonic frequencies and alternative methods.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests clarification on how mist makers function, mentioning they heard ultrasound is involved.
  • Another participant expresses unfamiliarity with the term "mist maker" and asks for a product link.
  • A humorous comment suggests that mist makers are created by trained monkeys, adding a fictional element to the discussion.
  • A participant provides a link to a product catalog, indicating they believe the OP is referring to specific mist-making lamps.
  • One participant proposes that mist makers operate by using a submerged ceramic diaphragm vibrating at ultrasonic frequencies, but they are uncertain about the underlying mechanism.
  • Another participant speculates that dry ice might be involved in the mist-making process.
  • A detailed explanation is given about the use of a submerged piezoelectric crystal that emits ultrasonic waves, creating microscopic droplets through surface tension, and clarifying that these devices do not heat water or produce water vapor.

Areas of Agreement / Disagreement

Participants present multiple competing views on how mist makers operate, with no consensus reached regarding the exact mechanisms involved.

Contextual Notes

Some claims about the operation of mist makers depend on specific assumptions about the technology and its components, which are not fully resolved in the discussion.

Hello people,
please, can someone explain how mist maker work?
I heard it use ultrasound, but don't know how works.
Thanks

I've never heard of a "mist maker" - do you have a link to a product?
 
It's made by highly trained monkeys from brazil.

It is said that there is currently only one functioning socalled "mist-maker" left in the world, although it's location remains unknown...
 
I think these operate by beating a submerged ceramic diaphragm at ultrasonic frequencies, but no idea why that works (nor whether the effect occurs at the diaphragm itself or at where the ultrasound is directed on the water/air surface).
 
I thought they just had dry ice in them!
 
They use a submerged piezoelectric crystal somewhat underneath the surface of the water to broadcast an ultrasonic beam upwards. This puts high frequency waves on the surface, where surface tension causes some of the wave crests to pinch off into microscopic droplets that are propelled into the air, where they float around as mist. It doesn't heat the water, and it doesn't produce water vapor, which is transparent. They make lots of teeny tiny droplets which, if the sides of your container aren't high enough, will float outside the bowl and get everything around them very wet. They don't work well if submerged too deeply in the water, and they don't usually put out a large volume of mist like you'd see in a theatrical production (for that I think they use dry ice and it's a completely different process).

Hope that helps.
