Nope, sorry the info on Coke is not false. I have a friend who works in the hotel business and he told me this story...One night he was managing a huge banquet at the hotel. A large container of Coke syrup got busted and went all over the floor in the back hallway. Everyone was too busy to stop and clean it up, so he was walking through it all night and it covered his boots. When he got home he was so tired he just pulled his boots off and left them by the front door. The next afternoon he went to get his boots and they were hard as cement and the Coke had eaten through the leather of his work boots. He said he hasn't had a Coke since then. Neither have I since he told me that story.

Actually, if you check it out on TruthorFiction.com, they say all of them are true except three (not the three you mention, by the way). And they don't say they are false, just unproven.
