Turing a vape devie into a portable mini smoke machine

Hey all :)

So, for a new project I need to create short bursts of thick white smoke in a safe way. I’m building a new shoulder plushie of Mushu (the dragon) and I’d like to have him eject puffs of smoke out of his nose on demand.

I was thinking of using a vape device as these are small, portable and generate a lot of thick smoke. Of course I’d use a non-nicotine, non-flavour juice which to my surprise do exist.

Has anyone ever taken one apart or know a bit more of the inner workings on activation. I understand that some require push of a button or work on inhalation trigger (not an option of course) ?
