Video of a historic attempt to reproduce wombat, quasi-cubic poo

This historic (2998) video by Robyn Lawrence documents an attempt to understand and reproduce the forces and constraints that allow or induce wombats to produce somewhat cubic excrement. (Thanks to Pat Kight for bringing it to our attention.)

Currently, Patricia Yang [pictured here], a graduate student at Georgia Tech, who shared the 2015 Ig Nobel Physics Prize, for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds)—is working on the same general question.
