Yesterday I've seen a wonderful routine: at the beginning there were to cylinders with two botlle below and two handkerchief on the cylinders.
There were lots of gags exchanging one bottle for the other one ( the one with a red handkerchief and the other with a green one changed place evry time) and at the end of the routine under the cylinders there were one bottle with a purple handkerchief and one with a yellow). The magician at the end of the show said that the bottles under the cylinders were 10 or 12. I wonder if this is the effect called passe passe bottle or multiplying bottles: I can't tell you that it is GREAT!
Any suggestion on a model not very expensive but of nice quality?

Thanks/Fabio

I think that is Marconic's routine. YOu will need to find his book. However, if you have the bottles you can probably reverse engineer the routine on your own.
