The people of MaP (Maximum Performance) are devoted to one goal: improving the design of flush toilets. In order to effectively test toilets, they need a material that accurately simulates human-delivered content. Their research led them to create 350 gram segments of soybean paste, which are dropped into a toilet from an appropriate level and location.

My work here is done.
"Today, MaP-approved toilets can flush 1,000g of solid waste (over 2 pounds!) -- far more than an human is likely to produce."
Be sure to check out the other pictures, especially the stack of 5-gallon buckets of . . . material . . . for shipment around the world.
Gimme some coffee and a good book and let the experiment begin.... though it has been awhile since I have met a toilet that didn't make a death rattle while handling my best work.
