okay, it's a rather unsavoury topic but saari's potty is just *heinous* nasty. for some reason, if the urine isn't cleaned *instantly* (while still warm, i mean), it develops a thick crust that resists everything - vinegar doesn't dissolve it and the only way to get it off is to chip at it with a metal spatula.
there were five components identified but the only ones i remember are: potassium nitrate, urate, and ammonium. no calcium.
so while toodling around the net doing random lookups, i came upon this little gem:
"Potassium nitrate is also used as a fertilizer, in amateur rocket propellants, and in several fireworks such as smoke bombs."
...... i just had a vision of saari farting and ending up being launched sky-high off her potty....
