I use safale 04 and for 2 days there is about an inch of white foam on the brew. There can only be contact at the liquid foam interface, surely ? Then on day 3 no foam left and bubbles rising to the surface from within the brew. I have never tried a bottom fermenting yeast but would expect similar for first 2 days.
