A guy that regularily writes articles in PFK told me that he pees in his tanks to cycle them... Craig someone but I can't remember his surname. I considered it but didn't know the quantities and my girlfriend at the time told me if I did she would leave... On reflection I should have done it.
I think you would have to be careful about the pub though, I'm sure I read somewhere that if you drink alcohol of more than 17.5% it your body won't process it fully and your pee will start having a %proof! I wouldn't start recycling your tequila slammers though.
ACF's were the original pregnacy test and will spawn if subjected to pregnant womens pee.
Todays iffy wee facts!
