Bluelighter
I have a big blue springer, its an Agung job. We call him Blue Boy.
Submerge the bottle screw on the cap (now with your conepiece in it) load it with mull. When you pull the bottle up "Gravity" (it's really a suction effect but meh) will pull the smoke into the bottle. Now you have a 2L bottle full and ready to take in one big hit.
