I DONT THINK SO!!! My dear I have enough champagne bottles to try that theory out and as soon as you finish your bottle *blessed* it disappears!!! This is a pink bottle the champagne looking one says its filled with water and blessed. So my friend on Pacific dont empty it out. Its probably rare and you and I both got one....
Pardon me saying so Kurgan but you must do your research before making such accusations!!
You have to target a wave tile. The one I always used for that sort of thing is the one that's around the middle of the Vesper bridge that's going W/E, on the East side of the island with the bank. Not all waves will fill things like that, but most do.
It also takes till server up to show the new name.
I'm with you. There may well be a rare type, I am no expert but I have made bottles of water from champagne bottles in just the manner described also from Vesper Bridge. After you get the message 'you fill the bottle with water' it appears nothing has happened. Next time you log in however you will have a pink 'blessed' bottle of water.
However do NOT empty the bottle first, just click it and target the wave.
