Low-budget animation on making salt

Untitled from Mary O'Reilly on Vimeo.

I made this quick animation for my chemistry students this week as a lead-in to talking about the Born-Haber cycle, which describes how much energy needs to be put in and how much is released when sodium chloride is made from sodium metal and chlorine gas. The YouTube video I showed of it actually happening is way cooler. I didn't bother trying to compete with that.
