Today I was roaming on my iPhone to notice a Pop-up ad from Coca Cola. The ad promotes a Game that you can access on your iDevice, Slide your finger across the bottles (Coca 12oz Bottles) in a time limit to proceed to the next step. Step 3 is get 12 bottles in 12 seconds. Fairly hard! BUT finish it and It'll ask for your E-mail Address & D.O.B (To verify you're over 13 years of age.)

iPhone 3G/S lags a lot, may not work to your liking
In return they will send you a $12.50 iTunes Gift Voucher for iTunes US Store.
Note: The link above only works on iDevice, So don't whine if your on a PC.
It's hard to find the link, but I did manage to find one that has a direct link to the game.
