Cork and cage? How are you gonna seal it? IIRC, you'll have to use lower pressure if you're just going to cap it. I'm sure you've already looked into this part tho.After a chat with some other like-minded assholes on discord, we've decided that a champagne bottle is best because you can safely pressurize those to "shit's gonna go everywhere" pressure. Throw in some soap too so it foams everywhere.
The big question is what to throw in there for the smell. Deer piss? fish sauce? dollar store perfume? some kind of hippie essential oil bullshit?
If you can use a brown bottle, I'd also suggest some of that bright orange dye.
