Your premise regarding the alka seltzer doesn't make much sense chemically.
In fact, the addition of the ethanol may increase the solubility of water in
the mix, since it is more polar than the normal hydrocarbons contained in
gasoline. However, it's been a long time, but if I find some Alka Seltzer we
can try it in my lab.
The difference between theory and practice is that in theory there is no
difference.
In practice, there is.
