bubbler

this may seem really stupid but what goes into the bubbler water? or the same solution as the generator?

I think you will find most of the guys here just use water. Some use tap and others use distilled. The basic idea behind a bubbler is 2 fold. First is to scrub the gas before it enters the engine. The second is to act as a flash suppressor of sorts. If you do get a backfire it should only go as far as the bubbler thus saving the expense and trouble of having to rebuild your cell. I hope this helps and I am sure others will chime in as well...there is a wealth of knowledge on this board.
