Question: will pool water turn blue if you pee in it

Answer: No, Urine-indicator dye is a substance which is supposed to be able to react with urine to form a colored cloud in a swimming pool, thus indicating the location of people who are urinating while they are in the pool. A 2015 report from the National Swimming Pool Foundation called this ``the most common pool myth of all time'', with nearly half of Americans surveyed by researchers believing that the dye existed.
