Salt Water!
It rusts faster in salt water.
Salt water does make nails rust faster than non-salted water, because when salt is added to water, it will rust the top layer of the nail, and then make the nail basically shed its top layer. Then the salt will rust that layer, and this process continues until the whole nail is rusted. Normal water can only really rust the top layer, and can't get to the rest of the nail.
The Oxygen in the water reacts with the iron in the nail, making Ferrous Oxide
Distilled water will rust a nail faster as distilled water contains higher levels of OXYGEN which is what causes OXIDATION or commonly referred to as rust...

The salt in the water will speed up the iron nail because the chemicals in the salt water on the nail creates faded substances
A nail is made of Fe. Rust is FeO. Water is H2O. Fe + H2O ---> FeO + 2 H
