A very nice glistening dough ball (from hand wetting for folding) in the bottom of a 12 qt tub. The expansion of the dough is quite visible in the air pockets forming near the surface of the dough as well as the stretching of the dough surface. This is very active considering it was folded just a few minutes ago.
