I don't have a pump, but I will figure out something......there are lots of ways to make a vacuum. Of course, one of those little hand pumps would be tits.
I'd need a filtration flask, a stopper, and the funnel (and eventually filter paper).
NO....I'm not making Meth!!!!!!!!!!!!!!!!!!!! Think more along the lines of "fun with capsicum".
Anyway........if anyone has one.....say.....in the 500ml and up range........I can trade cigars.
