Renuzit is the key, man. Buy some. Your other bet is to make one of those drier sheet things someone else mentioned, although I suggest using a plastic bottle and punching holes in the bottom because they last for months if you use a more permanent container.
I've made sploofs out of all sorts of shit... one time I'd had a really shitty start to my shift and it was cold and windy outside - I had to smoke, and I had to do it indoors. No drier sheets were available, so I took an empty cigarette pack and punched a bunch of holes in the bottom and one big one in the top. Cut up a coffee filter to fit inside the pack and placed it over the holes in the bottom. Filled her up with Wild Mountain Blueberry coffee grounds, and taped the whole thing shut. Exhaled through the top, the smoke went through the grounds and out the holes smelling like fruit, but the filter only let air through so I didn't spray weedy coffee grounds everywhere. So dope haha.
