Discovery channel's Mythbusters episode 113:
Adam and Jamie visited a zoo to obtain a variety of feces to try to polish. They tried to pick the most polishable candidates and baked them to remove the moisture. Adam tried to shine his poop with a buffing wheel, while Jamie reasoned that using a wax polish would result in a shine. Adam eventually sought the advice of an outside expert, who showed him that it was possible to apply a shine to dirt with a tedious technique. Applying this technique, Adam and Jamie were able to obtain very polished poop without using any foreign materials like polish.
In the episode "End with a Bang" (Episode 113) of the Discovery Channel series "MythBusters" that first aired on November 12, 2008, hosts Adam Savage and Jamie Hyneman investigated the truth behind everyday sayings. They used the dorodango technique to create dung spheres in order to bust the myth that one "can't polish a turd". Using a glossmeter, they measured gloss levels substantially higher than the value of 70 gloss units which is considered "high gloss". Savage's 106 gloss unit dorodango used an ostrich's feces, while Hyneman's 183 gloss unit specimen used a lion's feces.
