Flame Test- Lithium Chloride

This is the '08-'09 school year's flame test demonstration. It went better than last year's demonstration (I have 3 videos of those on YouTube), but not as good as my first year's still (I have 7 of those videos [e.g. http://www.youtube.com/watch?v=jJvS4u...]. The flame test is preformed by burning a metal salt using a flammable liquid. Each chemical (in this case metal ion) gives off a characteristic color (seen here as changes in colors of the flames) when the electrons fall back down from their excited state and emit light at certain wavelengths (colors). This year I decided to do something different and filmed each salt individually.
An alcohol is used to burn all of these salts, this one is lithium chloride (LiCl) which has a bright red or hot pink flame.
