Way back in highschool, I bought a bottle of titanium tetrachloride ( TiCl4 ) from a Hollywood studio suplier when I lived near there. ( I still have most of a quart left ).
It was (is?) used for smoke in theatrical productions and is sometimes called "liquid smoke". TiCl4 is difficult to handle 'cuz when you open the bottle, copious amounts of smoke obscure what you're doing, but we had fun with it, such as putting it into small vials, and throwing them down in certain places making huge clouds of smoke :-).
