Ok so literally-here's what I just did when I transferred to my secondary.
I drained out the beer until it stopped siphoning, took a sanitized jar, took some of the yeast cake out in a measuring cup along with some of the wort and put it in said jar, then i added some raw organic sugar to it to possibly give it some food to eat? It's gassing off, the top of the jar has pressure you can feel and it emits and audible "phhhhssshhh" when I open the lid to purge some of it. What could this do for me, I'm assuming it's useless but could I pitch into my next 5 gallon batch? Lemme know ladies and gents
