So I followed some guidelines online to toss together a stir plate and have found that after messing with the magnet placements I can get a good vortex working on enough water for a 1L starter but when I up it to 2L the funnel only goes about halfway down the flask.
Is this enough or is the funnel supposed to hit all the way down? I used some pretty heavy magnets I had laying around so if I need to I guess I could by some lighter powerful ones that could would let the fan spin faster but if I don’t need to I’m not going to.
