I have a client who uses one of those to vacuum seal his mason jars every time he fishes out a bud. He’s a bit OCD though. He also wipes the bowl with alcohol and a paper towel to leave no tar residue after every hit. and changes out the Bongwater between every hit on his pipe. And that was before Covid. I guess that way every single hit taste fresh.
I don’t usually change my water or wipe the bowl with alcohol until I’m worried about it spilling on the floor if you know what I mean. If I’m outside I just use my roller (I still can’t roll for shit, maybe it’s all in my head and I need to get hypnotized or something) and smoke that way.
