Kawah Ijen Volcanic lake on the island of Java, is the most acidic lake in the world, with a pH level that dip as low as 0.2. That’s enough to dissolve metals and burn skin on contact. Plus the gases emanating from the lake are so deadly, they can cause instant respiratory paralysis and death.

You would think no one would ever venture anywhere near this hell on earth, but you would be wrong.

Locals not only mine a volcanic vent on the side of the lake for solidified Sulfur, but around 300 tourists travel to the lake each day.

Thanks for watching.

► WHY THE FLAMES ARE BLUE

It all has to do with the chemistry of combustion, when a fuel like a sulfur compound mixes with oxygen in high enough temperatures a combustion reaction happens.

Heat gets released and new chemicals are formed like sulfur dioxide and the visible part of the fire is the flames which are caused by a bunch of atoms spewing out light energy.

Basically the energy from the combustion reaction boosts the electrons in the fuel atoms to a more energetic state.

When the electrons fall back to their original state they release all that extra energy as a photon of light. The wavelengths of those photons determine what the flames color is and in the case of sulfur compounds catching fire it's an eerie blue glow.
