simple smoke bombs

[sci-man]

does anyone know how to make a simple non-toxic breathable smoke bomb? this would be to study differences in air pressure and other studies like that without harming the enviroment

Burning fuel creates various intermediate toxic compounds. But if you would use e.g. dry ice, liquid Nitrogen etc. etc. or other cooled solid substance which is sublimating at room temperature, it could pretend "smoke"..

Search Google for "dry ice+water" e.g.

The view that nitrogen is a "cooled solid substance which is sublimating at room temperature" is- shall we say- interesting.

Dry ice is a good option

So is a smoke machine.

As always, John, you draw conclusions from words that have never been said.. "or other cooled solid substance which is sublimating at room temperature" means it's certainly not liquid Nitrogen.. (liquid Nitrogen is... hmm.. liquid, not solid substance....)

sensei, thanks for that but I'm looking for something that can burn without creating toxic compounds in the air so i dont harm anything in the sourounding area when i do the experiments and dry ice "smoke" does not fise like I need it to, also me being a teenager I cannot buy too many things like dry ice or liquid nitrogen on my own (so what i should have put was simple non-toxic cheap smoke bombs) but none the less I thank you for your imput on this subject.

Impact smoke pellets? From a quick google search it seems that it only requires powdered sugar and potassium nitrate.

I'm glad you have now realised that liquid nitrogen is  not a solid.What you said here

implies that you thought it was a solid; that's the implication of the phrase "other cooled solid substance".

 

Smoke pellets seem a much better idea.

This sort of thing.
