I made this short video of how to do the "spinning bowl" flocculation test:
Flocculation test (http://www.youtube.com/watch?v=VbxdJD21_5A#)
Thought this might be useful ...
[edit]
It shows the test at 10 minutes, 12 minutes and 14 minutes. At 12 minutes you can see that there is a very slight resistance to movement. The flocculation point was possibly actually reached about 30 seconds before the footage at 14 minutes - the bowl would still move given a gentle blow (rather than a nudge with a finger) at 13 minutes.

Very nice! For a newb like me, that video answered a bunch of questions... like what kind of bowl to use, how much the initial flocculation would resist the bowl, how hard you spin and nudge it etcetera. Thanks!

nice short and to the point video, thank you.
