OK, half a can of gas, not sure how much ethanol is in it, the pump says it can be up to 10%, added half teaspoon of water and about half an ounce of B-12.
Upon stiring the mixture turns milky then clears, no water beading. After it sat for about an hour there was a very slight "line", no beading, in the bottom that went away with a slight stir. It would appear that with any motion at all the water has been absorbed by the B-12. The evaporization test is in progress but will take a while.
