Ghost bottles and glasses have a habit of being shoddily constructed but this one is about as top notch as you can get. The only drawback is that there is a slight seam where the inner wall of the bottle is joined to the outer one. With the focus being on the disappearing soda plus a bit of distance from the spectators, this is an all but non-existent issue. The brighter color of the coke in the bottle in the picture here is a result of not adding red and blue food coloring to the soda. When you add the food coloring, the soda is dark as though it were a real bottle of soda. If you need a vanishing liquid effect for your show, you found your prop. 4.50 stars...
