The science of Monkey Island: can grog dissolve a metal mug that fast?

A science-focused blog post examines the feasibility of the 'Grog' drink from the video game Monkey Island, which is said to dissolve a metal mug in a matter of seconds. According to the game, a mug made of metal can be dissolved by a drink made from a mixture of rum, fruit juice, and a mysterious ingredient. The post delves into the properties of the ingredients and calculates the theoretical dissolution rate of the mug. It concludes that a mixture of rum and fruit juice would not be able to dissolve a metal mug, and that the idea of the Grog is likely a plot device. The author suggests that the game's creator, Ron Gilbert, may have used the Grog as a way to add humor and whimsy to the game, rather than to be taken literally.
