Yeah, there is copulation on the pipe.

Honestly, not worth fucking with a faucet to get a screen. If you're going to, atleast do it right, get some pliers and unscrew it. Removing screens fucks up some faucets to the point where they are unusable, so I wouldn't risk it.

Just get a piece of foil, push it in to the bowl, poke some small holes with a safety pin, and put a small about of herb in there. Start with that, go from there.

Also, don't put stems in there, and try not to put leaves in either. I took a hit with stems once and almost vomitted.
