Radium Gin (also known as “Madame Curie's Radium Gin”) is a large bottle of gin on top of Big Clive's electronics component drawers.
Despite the claims of the label it does not actually contain radium, but is instead enhanced with a pinch of sodium fluorescein dye which is better known as drain tracer, there is debate whether or not this dye is suitable for human consumption.
Later mica glitter was added to the recipe to make it shimmer in the bottle.
