Discussion Overview

The discussion revolves around the possibility of creating smoke effects similar to those produced by pyrotechnics without the associated heat. Participants explore the nature of pyrotechnics and whether it is feasible to generate smoke without significant heat production.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions the necessity of extreme heat in pyrotechnics and wonders if a safer alternative exists.
  • Another participant seeks clarification on whether the inquiry pertains to flame without heat.
  • A participant suggests that while flame and smoke are different, devices like fog machines or smoke grenades might be relevant, although they express uncertainty about the heat generated by these devices.
  • A link to a fog machine article is provided as a potential example of generating smoke.

Areas of Agreement / Disagreement

Participants express differing interpretations of the original question, with some focusing on the distinction between flame and smoke, while others explore the feasibility of creating smoke without heat. The discussion remains unresolved regarding the specific mechanisms or alternatives that could achieve this.

Contextual Notes

There is uncertainty regarding the heat output of fog machines and smoke grenades, as well as the definitions of flame and smoke in this context.

Hello

I'm new here at Physics Forums and have been struggling with understanding how a simple
pyrotechnics works, and thought I'd try you guys.

As i understand pyrotechnics heat up, making them very hard to control and dangerous to people around them but is the extreme heat really necessary?

Is it possible to create something that looks like pyrotechnics but does not last as long and does not come near the heat?

Thank you and please excuse my ignorance

You mean flame without heat?

I guess you could call it flame, i mean a "firework" like the one in this video;
And then the smoke like the one in this video;
 
Flame and smoke are completely different things. I would think you'd be familiar with something like a fog machine or smoke grenades(though they probably heat up, I just don't know how much), so I assumed you meant something else.

And then you mentioned pyrotechnics.
