Specific type of gas
« on: November 17, 2020, 07:35:09 AM »
Hi there, I have an idea for a cool project and I need your help with it...
I'm looking for a type of gas that you can squeeze into a can.
that when released slowly, it spreads in the air in a way that is thick enough that you cant see through it.
it has to be non-poisonous and completely harmless.
it needs to function as a screen.

can you please help me to find the right type of gas or compound for the job?
p.s I'm sure not a chemist.
thank you!

No such gas.

If anything, fog or smoke bomb works this way.
