Metal Gear 2 - Solid Snake (1990) (Konami) (J) 0025

Solid Snake encounters some puddles of sulfuric acid in 1999.

Sulfuric acid, also spelled sulphuric acid, known by the chemical compound H2SO4, and originally known as the oil of vitroil, is a highly corrosive mineral acid with enough dissolving power to burn the flesh off people. It is recognizable as having a colorless/slightly yellow coloring with a pungent ethereal nature and is soluble with water in all concentrations. Because of it not immediately being recognizable, it is frequently dyed dark brown to alert people of its danger. It can be neutralized if caustic soda is placed over it, and can also produce carbon to transform into a rubbery substance if anything containing table sugar (C12H22O11) is exposed to it.


Zanzibar Land Disturbance

Main article: Zanzibar Land Disturbance

The detention camp of Zanzibar Land had various puddles of sulfuric acid spread across the prison facility as well as the secret Metal Gear D hangar. Although their use by the Zanzibar Land personnel was intended to be to ward off the Zanzibar Hamster infestation due to their being pests, the puddles also acted as a huge obstacle for the FOXHOUND agent Solid Snake during his mission into the nation.[1] Using some advice from Master Miller, he used some chocolates in the B1 Zanzibar Land rations to neutralize it.[2][3]

Behind the scenes

Sulfuric acid is an obstacle in Metal Gear 2: Solid Snake. If the player walks over a non-neutralized sulfuric acid puddle, Snake will sink down to nothingness, earning an instant game over.

    Kid: There's lots of rats in the jail. They steal all kinds of things and take them back to their nests. The grown-ups put out sulfuric acid to try and get rid of them.

    Master Miller: How to deal with sulfuric acid? Hmm... let's see... You could neutralize it if you had something with caustic soda in it... I got it! ...You got any chocolate on you? That ought to do the trick. Sulfuric acid reacts with the sugar in the chocolate to produce carbon and a rubbery substance, C12H22O11... table sugar. See if you can find some chocolate...Over and out.

    Kid: I want chocolate! Mister, do you have a B1 ration? B1 rations have chocolate in them.
