I never drink Coke (or any of the other variants) ... or any so-called "soft drink" for that matter. If pressed I might manage a Fanta or some such diluted 50/50 with water!
But ... as Umish has mentioned, Coke (Pepsi et al
have usefulness as an industrial strength service consumable!
The thought occurs that it might be handy for cleaning blood sampling valves (and the like) on old Coulter Counters!
Drink it? It's too good to waste on that!
