SUCCESS
So I checked on the yeast I washed and harvested from my hefeweizen... and it worked!

The white stuff on the bottom is the yeast. What does this mean? I don't have to  pay for yeast when I brew my next hefeweizen batch! Hurrah!

FAILURE
So after I concluded that my yeast washing attempts had been succsessful, I was gonna post a guide on how to wash yeast... then I fricked it up royally. I didn't sanitize the jars >.< Anyway,  next time I'll do it right... I hope.
