Can anyone explain what I saw happening in my fermenter? After the yeast had started to floc and settle out, I noticed these "geysers" shooting off the yeast cake on the bottom of the fermenter. Very cool and mysterious. Check it out:

That is just CO2 evolving from the yeast cake, and it pulls up some of the yeast as it rises to the surface. Depending on the flocculation/sedimentation properties of different yeasts, you will/will not see this sometimes.
It is cool lookin'.

Kind of Lava lampish. Perfectly normal.
