I've been searching around for a while now and I haven't had any luck in finding an efficient method of creating pure bromine liquid. Any help would be much appreciated.

In my opinion, the simplest way to make relatively pure Cl₂ gas is to obtain MnO₂ from a zinc-carbon battery (its that brown-black paste-like stuff between the outer shell and the carbon electrode), pour in a little hydrochloric acid, and set up a simple apparatus in order to bubble the Cl₂ gas produced through some water into a test tube. Voila. Isolated chlorine gas.

The chemical equation of this reaction is: 4 HCl + MnO₂ → MnCl₂ + 2 H₂O + Cl₂

For those of you who are curious, this method of creating chlorine gas was actually how chlorine was discovered. It was discovered in 1774 by Carl Wilhelm Scheele.
