Indeed, the composition of urine is even covered by a FAQ at the
Singapore Science Centre.
Question No. 9245 :
What is the composition of urine?
Urine is mostly water and contains organic waste products such as
urea, uric acid, and creatinine, as well as excess ions such as
sodium, potassium, chloride, bicarbonate and hydrogen.
Concentrations (average values) of major substances in urine are as
follows:
Water 1.4 L/day
Urea 1820 mg/100mL
Uric acid 42 mg/100mL
Creatinine 196 mg/100mL
Sodium ion 128 mEq/L
Potassium ion 60 mEq/L
Chloride ion 134 mEq/L
Bicarbonate ion 14 mEq/L
pH 4.5 to 8.0
Never mind that the question was asked by someone in age group 6 to
12.

William Shatner drove to that location and walked around on the rocks
(interspersed with footage from "Arena") in the "How William Shatner
Changed the World" TV show.
