The Flusher King
`To objectively test the flushing performance of six-litre toilets, Gauley first had to develop a “test specimen” that would better replicate human waste than past “non-realistic test media (sponges, plastic balls and beads, craft paper, etc.),” the current report says.
“For a long time someone would try something and say, `Hey, I found this Play-Doh’ and we’d sit around the boardroom table squishing it through our fingers,” Gauley recalls.
He and his team eventually found a material that eerily replicates the density, moisture content, and other properties of the real thing: a brownish soybean paste imported from Japan in 20-kilogram containers. It’s better known as miso.’
