What is the deal with lightning and scuba

[scubafool]

Yeah, they do, that's why I always leave behind my beercans when I am done drinking them during a drift dive. :11:

ummm this is kind of random, but here it goes.

i remeber a couple years ago maybe when i was 12 or so we did an science experiment that involved passing a current through salt (NaCl) and splitting it into chlorine and sodium.... now this is kind of far fetched, but if i took a car battery down to the ocean and stuck the two wires into the water, would Na and Cl start to come out the sides like it did five years ago?

I sell systems that do exactly that in a swimming pool. But in pools we maintain a 3000ppm level of salt, much lower then the ocean.
