Well, I just learned a very valuable lesson...
After taking the sg of the MB - still at 1.010...I decided that maybe there wasn't enough sugar to feed the yeast, so I poured a 1/2 cup, mixed it with warm water and poured it into the carboy. By my cals, the water/sugar mixture should be enough to top it off, but after I poured it in, it fizzed up so much that it was like a volcano all over my basement floor. I was truly amazed and am still keeping my title as Virgin Vintner. After it cooled down, my gravity thing (bubbler?) is fartin away. How nice...
