Since water is H2O there's only half the O molecules so there's less gas at the positive electrode. Also, the O bubbles are very small and aren't very noticable unless you've got lots of it being produced. Btw, stainless steel pipe in varying sizes makes a great generator used with large 2-4" diam. rubber pipe caps. I have a little unit that will make one liter of H and O gas in about a minute, I think it was. Kevin[ Parent ]
