Here's how it runs. 4 mins was enough to mix with minimal bubbles:

Are bubbles bad? I usually shake the shit out of the bottle until the bubbles are fully dispersed through the liquid.
I'm also curious about this because when I shake mine I always create a lot of bubbles that sometimes stick around for a day or so. You'd think bubbles are a good thing, that it helps with the oxidation of the juice.
Why not make a magnetic stirrer instead?
I mix in 20ml batches. I find it very small amount to deal with the overhead of dirty dishes. If I were mixing 100ml or more probably this would be my preference too.
Yeah that's cool and all but a magnetic stirrer would probably be more efficient and easier to build too ;)
I hear the magnetic stirrers don't do well with thick liquid, so if your making 80% VG and up it might not work as well. Maybe there's some higher power ones out there.
