I think Citric Acid would work equally as well (or as bad depending on your perspective).
What was with mine was labeled "non-toxic", so I tasted it MANY years ago (20 or so) and it sure tasted like Potassium Alum (used for making pickles) to me. (Foolish, I know and would never do something like that now)
Using straight white vinegar as the "oxidizer" produced flights that were consistently higher.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
