Urine is sorta acidic, at very large amounts could it burn your skin? 0.o
sorry, random questions come to the mind when relaxed.
It can most certainly burn your skin. That is what a diaper rash is.
I don't think ? People pee or get peed on their leg when a jellyfish stings them I think:p
Yes, but according to Bear Grylis it's fine to drink. Ewwww!
No. The acidity does not change with volume. If a little wont burn you, neither will a lot. But if concentrated (e.g. by evaporation), then the potency increases and with it, the potential for harm.
