Hah! I guess I knew that but didn't catch it like you guys did! Water is indeed heavier than gas. I wonder if the original writer also wrote it backwards (ie maybe in Portugese?) or if it was translated wrong? In any case, it was pretty bad to print that.... I agree.

Ok, aside from the obvious editorial errors, I've been thinking about the process, and I won't be doing it myself unless someone I know with a chemistry background indicates there could be some overall benefit.

My thoughts are these:

1) If tap water is used, will it leave anything behind that the gas will pick up? (ie, in which case one should really use distilled water?)
2) Will the absence of the alcohol really be an improvement (additives used in this gas or lack of themdesigned to work with the alcohol won't work WITHOUT the alcohol being there)
