Try again?

I can win personalised colourful converse trainers.

I have to open my bottle and probably drink the contents.

Then i take a photo of the front of the bottle with the flash on. Now when i check my photo, if "WIN' sparkles in the photo I am a winner. How cool is that.

There's 5,000 pairs to be won.

This one is not a winner.

Shall i try again?
