Where did you hear Coke has a ph of 3? Seems way to acidic to me.

Try sticking it into some vinegar or lemon.

I just picked up a Rapitest PH meter from Home Depot and I'm suspicious
of it's accuracy. I stuck the probe in to a glass of Coke and got a
reading of 6.25 which is way to high, Coke has is supposed to have a PH
in the neighborhood of 3. DOes anyone have any experience with these
meters?
