If you had a bathroom at earth room temperature and pressurized to a generic earth air pressure standard, could you flush a toilet on Ceres?
I'm not sure how lower gravity would behave in regards to poo buoyancy. Would it swirl in the bowel? If a bidet was used, would the water arch or go in a straight line, capable of making escape velocity? Could the splash back from a turd taking into the water rocket you to the ceiling?
Would liquid water fall quicker than a turd formed by us, our digestive process being based on earth, leaving turds extraordinarily boyant, unable to fall without being hosed down? Or would our be super heavy, and we would near a heavier liquid like motor oil to hold them in the toilet for easy flushing?
How would plunging a toilet in low gravity conditions of Ceres work? Does human earth norm strength run the risk of sucking all backed up sewage in the sewae tank back into the restroom? If you plunge too hard, could you be surrounded by a ocean of old sewage from weeks earlier, flooding the bathroom?
