Return to Question

I recently saw this Periodic Video.

The Professor (Martin Polyakoff) notes that,

1. The Gherkin normally glows only at one end due to excitation of $Na$ ions.

2. The end which glows can either be the neutral end or the positive end. It is impossible to predict which one will glow.

3. During the video, both ends glowed together only for a few seconds.

Even the Professor admitted that probably glowing at one end happens due to pure chance.

Why should the gherkin glow only at one end? Is there any reason? Normally one would expect it to glow symmetrically around the center, that is, at both ends.

The question has been quite well received. However no one has commented or answered. Does the question need to be re-worded or better explained?

Do let me know in the comments.
