Aqua Regia is a cocktail popularized by the Romans who fed them to Christians as a means of harmless recreation (hence the latin-sounding name). The Science of Mixology, puts Aqua Regia a step above Absinthe and a step below
Strychnine in the Mixological Periodic Table. It was a popular drink among the aristocrats and royals (hence the royal sounding name), who used it to open political doors by corroding the iron curtain (figuratively, of course). Aqua Regia is considered to be the hardcore predecesor to LSD, and it is widelybelieve that LSD wussified the Acid scene.
