Simple Water Electrolysis System

Collecting Hydrogen and Oxigen using only tap water, salt and two laptop charger

Take a little plastic bowl and fill with salt solution

Using two big screw as electrode. One as Anode and one as Cathode

The electric flows must be Direct Current (DC) remember, must be DC, AC current won't work. I use two 24v DC Adapter from computer charger connected in serial to gain the voltage to 48v with the current flow about 6 amps.

Using water bottle

The Electrode with more bubble is Hydrogen . Choose what you want to collect and then flip the bubbler over the electrode

For Hydrogen: Using lighter to test. But remember : Pure Hydrogen is flamable, but Hydrogen with Oxigen is highly explosive, the amount of hydrogen and oxigen with the ratio of 2:1 in a big bottle can blow you up, so be careful
