Cool, that makes me feel much better. I had him practice on a few empty bottles first. I also had him place the caps on the bottles rather than sticking them to the magnet, just to make sure they were seated.
I've got a funny story about that night too. Before priming, I filled my tube and took my hydrometer reading. After that I took a sip and offered a sip to my buddy. I explained not to get too excited as it was warm and flat. The look on his face was priceless. Needless to say, he drank a pint glass of the stuff after all of the gift bottles were full. I guess he liked it...too bad I could only send him home with one bottle from this batch.
