How's that work again, Denny? What's a "glass column?" Are you watching
the level to see if the alcohol evaporates?

Take a mason jar and fill it about 1/3 or the way with water. Mark the level.
Then add at least that much fuel. Cap and shake and let the water settle. If
the water level is higher after this, you have alcohol in the gas.

Basically, alcohol will mix much more readily with water than with gas, so the
alcohol will come out of solution with the gasoline and mix with the water.

Interesting idea. Is there really enough alcohol in the gas to
substantially alter the level of the water? I would think it would be
hard to discern small amounts.
