The science of Monkey Island: can grog dissolve a metal mug that fast?
A chemical engineer calculates that the fictional beverage grog from Monkey Island would require an impossible 383-molar proton concentration to dissolve a pewter mug in 35 seconds.
summary is enough The playful chemical breakdown is fun, but the core conclusion that fictional grog defies ordinary aqueous acid chemistry is fully captured in a summary.
summary
A researcher modeled the rapid corrosion of pewter mugs by grog in the classic adventure game The Secret of Monkey Island. By timing the in-game dissolution at 35 seconds for a 2 mm mug and applying a stagnant-diffusion corrosion model, the author calculated a required proton concentration of roughly 383 M. This far exceeds physical limits for aqueous solutions, demonstrating that ordinary acid chemistry cannot explain grog's potency. The author humorously concludes that the mysterious fictional ingredient SCUMM must act as a voodoo-powered oxidant.
key points
- An in-game pewter mug dissolves completely after being filled with grog for approximately 35 seconds.
- A stagnant acid-diffusion model estimates a required proton concentration of 383 M to achieve this corrosion rate.
- Because 383 M far exceeds standard aqueous acid limits, ordinary chemistry fails to explain grog's behavior.

True, but mercury does not dissolve the iron of the lock. For that, the sulfuric acid is necessary.
If grog would contain both mercury and acid, they would not mix, but there will be a mercury layer at the bottom and the acid solution would stay at the top. So the mercury could dissolve the bottom of the mug, while pouring some acid from the top could dissolve the iron lock.
The fact that iron is among the few metals which are not dissolved by mercury had been widely used in the past, when the use of mercury was less restricted. For example, ignitrons and mercury arc rectifiers, which were …
It extends the article's chemistry breakdown by analyzing how layered mercury and sulfuric acid could theoretically attack both pewter mugs and iron locks.
