By applying the current from a 9 volt battery to a glass of water via two standard pencils used as electrodes, electrolysis takes place, separating the water into hydrogen and oxygen gas; hydrogen at the positive electrode and oxygen at the negative.

Lit by two speedlights; one gelled through posterboard for a backlight and one bare to camera right.

RAW adjustments, curves, resize, border, USM, save for web.

Cool shot, and a nice demonstration. May I suggest tightening up the crop a bit to lose a bit of the bottom and keep attention on the subjects. Great job at focusing through curved glass!

I agree with the title and it is a great idea. It's just not IMO a good looking photo. Who wants to look at a battery? But I understand you had to have it there in order to prove your point...

It would have been somewhat better to me if at least the pencil had been in focus.

Fun with science! Been too long for me so I'll check your notes after to see what element in the pencil reacts.
