Don't try this, but if you do you'll learn.....
put 3 tsp of epsom salt in a glass of water and chug it down.
Not long thereafter, you're shitting water out the rectal seal. So what do you next do ? Drink a glass of pure water. More water out the butt. Rinse, repeat.
Eventually the rectal gusher stops, and the water you drink will come out of r1.
I view the buttgusher as the body being overloaded, and the little man at the lever down there says "Whoa, overload magnesium!!" then he discharges it from the system the quickest way possible, until things return to normal, r2 is closed, and r1 open.
