Do Spanish pools really make your pee turn blue or was this a lie my parents told me?
As a child in the 90s - when we went on holiday to Spain (or other Mediterranean countries) my parents told me that there was a chemical in the pools that will turn your pee bright blue so everyone will see - this is something I've believed for 30 years.
However, it just occurred to me that this might have been a lie told to children to stop them peeing in pools?
Was this ever an actual thing?
