This Friday, March 20, is the International Day of Happiness. And based on the photos we receive every day, many of your moments of happiness are accompanied by none other than a cold bottle of Coke. We're honored to play a small part in those happy memories.

So this year, we're not just celebrating the Day of Happiness - we're celebrating 100 years of the classic glass contour bottle. And we want you to join in! Take a snapshot or video of what happiness means to you (including a Coke bottle, of course) and share it with us by uploading here. We might just feature it here at Coca-Cola Journey!

Take a look at what people have already sent our way:
