Re: smoke generator



Try a fireworks store or a magician's supply. (Or ask your state
government's budget people for some surplus smoke and mirrors. . .)


Eugene,

There is, or was, a comercially available product called "touch paper".
It was essentially a tissue paper soaked in a concentrated solution of potassium
chlorate (KClO3) and allowed to dry. When a small piece of this paper, about 2
cm square, was ignited with a match, it would quickly smolder to ashes and
produce quite a bit of white smoke with little odour. The smoke particles are
probably very small which may have some effect on the observability of the
precipitate in your demo. Good luck finding or making something that works.
Let us know what you find.
