Coca-Cola

Just when you thought you knew everything...

AND WE DRINK THIS STUFF!

FYI... the active ingredient in coke is phosphoric acid. Its pH is 2.8. it will dissolve a nail in about 4 days. The distributors of coke have been using it to clean the engines of their trucks for about 20 years!

Drink up!

Just to be fair, you should realize that it's not only Coke that can do this... probably most colas can.
And the Coca-Cola website has some info refuting this here and here.
