Advances in toilet system testing: Wigglers & Pseudo Poop
Whither waste? Toilet testing, not everyone’s cup of tea, makes things flow better, for society’s sake. Metafilter features a little roundup of toilet testing info (thanks to investigator Scott Langill for bringing it to our attention): Pseudo Poop for Testing Toilets Testing toilet flush performance naturally requires the replication of real-world loads. Striving for accuracy, […]
