If you always thought toilets just worked, be prepared to reassess. A company called Maximum Performance dedicates its activities to optimising your bathroom experience — and that's led it to develop fake poo for testing toilets. Really.
What you looking at is a stack of 350g segments of soybean paste, specially mixed and extruded to simulate real-life, human-delivered toilet content. Once formed, the soybean cylinders are dropped into the bowl from an appropriate height and location in order to accurately recreate the loading a toilet experiences.
From there, uh, I guess it's possible to make more effective bowls and flushes and things. Whatever, just be glad your job isn't dropping fake poo into a toilet all day. Imagine explaining that to a date... If you want to learn more about the whole process — and why wouldn't you — Maximum Performance has a page explaining the entire thing, start to finish.
