Caution: the following post is not for the faint-hearted. You must LOVE chemistry in order to understand and appreciate the coolness of this experiment.

Some simple facts about Hexane and its properties:

Since hexane belongs to the alkanes, it follows the general formula C_nH_2n + 2.

 Alkanes are saturated hydrocarbons, this means that not only they consist only of Carbon and Hydrogen atoms, but these atoms are linked together exclusively by single bonds.

Hexanes are mainly obtained by refining the crude oil through fraction boiling. 

The figure below shows simple setup that mimic the refining of crude oil.

In industry, hexanes are often used to manufacture strong glues, remove grease, or to extract cooking oils from seeds.

A special kind of hexane, called the Cyclohexane, is used as a nonpolar solvent in the chemical industry due to its inert property.

Both Hexane and Cyclohexane are highly flammable, so please be careful when you are carrying out an experiment involving these two substances.
