I am interested in learning to make my own ooze, and figured out that the only "right" way is to mix wax with perc in order to obtain a mixture that's denser than water. The other way would be to make the water less dense, but that inevitably means mixing it with flammable liquids such as alcohol, which I don't want to risk.
However I have problems obtaining pure perc where I live, and there are few details around the net over e.g. which specific products contain it, if it's pure, how it's supposed to be mixed etc.
The closest I've found is a can of circuit cleaning spray which says it contains "Tetrachloroethylene", but I don't know at which concentration and degree of purity. Am I supposed to spray and collect it in a separate container to have pure perc to mix in with wax?
Exactly how is the mixing done? Do I just pour it into molten wax and stir the concoction? Won't it just evaporate too quickly?
What other substances can be used for the same purpose (not many, from what I've gathered, but it doesn't hurt to ask) ?
Also, which household, easy to find products contain perc, even if not necessarilty pure? (e.g. what about oven cleaning products and creams etc.)
