I guess this really could apply to any AS splash, but when I try to get a little bit of AV into my hands, I always tend to spill a little bit/drip some down the bottle/so on and so forth. This might just be because of the wide opening at the top. I tried sticking a small piece of a cotton ball in there, but it acted more as a stopper than a flow/drip controller. Any suggestions to keep things neat?
