I think it would be interesting to replicate the experiment in this video using my high voltage generator.

Here is an interesting experiment that I am replicating from the JNL website. It is high voltage electrolysis that creates a an underwater plasma, but only on the negative electrode. It requires the use a asymmetrical electrodes, and I must admit, I can not explain the physics behind this phenomenon!? A very interesting video to say the least! Included is a link to the JNL webpage.

The Asymmetrical Plasma Electrolysis (APE) is a simple experiment which can be easily performed with few material and uses a common lab equipement. This experiment will demonstrate you very easily that a glow discharge plasma can be observed on the CATHOD during an electrolysis process at a high voltage ( ~ 200 V DC ).
This is the main process used during the high temperature plasma electrolysis (CFR) experiment from Tadahiko Mizuno from the university of Hokkaido in Japan.
A similar experiment has also been performed by Renzo Mondaini (Italy).
To conduct this experiment you need :
1 auto-transformer (0-270V) 13A, 3.51 KVA
1 circuit breaker (230V, 16A )
2 diodes 400 V 5A
1 capacitor 2200 ?F, 500V
1 borrosilicate beaker ( 1000 mL )
2 pure tugnsten rods (commonly used for TIG welding) 2 mm diameter 150 mm length
400 mL of a solution of Potassium Carbonate (K2CO3) at 0.2 M
