I tried the Alka Seltzer trick on some denatured alcohol -- no result.
It did not fizz!

You know I've been wondering: Does the Alka Seltzer trick really check to
see if alcohol is present? I'm no chemist, but I wonder if the Alka Seltzer
is just reacting with the water that most alcohols will attract from the
moisture in the air.

How about it? Any chemists in the group? If the mogas were blended with
alcohol with low water content, would the Alka Seltzer fizz at all? Maybe
the best test is still the "line on the beaker" test.

Seltzer reacts with water.
