Viscous Flow of Bread Dough

Bread dough is stiff but still flows. A big blob of foodstuff that slumps over time, like Silly Putty but large and edible.

Make bread dough enough for a couple loaves, and knead it stiff enough that a round ball of dough takes half an hour to slump to half its original height. Place on a plate, put a camera on it. Project the image at the beginning, just as the dough ball is released, and again some time later, after viscous flow.
