Um, not to take away from the achievement of the result, but couldn't this result have been obtained in much less time with higher force than 1G in, say, a centrifuge?
In other news students preferred "watching the pitch" over lectures by a margin of 2 to 1. :-)
They learned as the pitch flowed!
Well, where's the fun in that?
That would be another variable to account for and isn't the a standard test for viscosity. Also with pitch being this viscous having a centrifuge capable of spinning fast enough and long enough would be troublesome.
