I made a very simple Sammy Summer clone today. All was well until I went to add the yeast. I already had my blow off top on and the other end was immeresed in the bleach water solution. I noticed some od the bleach water solution was about half way up the tube and I wanted it back in blow off container so I lifted the tube up a little and opps the preasure from the carboy suckked the water right into the wort. I opened it and I can smell the bleach faintly. I guss I'll pour this one out. Lesson in preasure learned!
