Forgive me if something like this has already been posted. I'm kinda new here.
I drilled 2 holes (needs a vent or it will fill the cup and air tube with liquid) in a syringe bodied CE2 and slid a sleeve cut form a cart condom over the barrel. Slide the sleeve down over the holes after filling. It still needs a syringe to fill but it only takes a couple of seconds.
