Show the Coke bottle full.  Now roll up a piece of newspaper into a cone shape. 
Pick up the bottle and slowly pour the coke into the cone. 
When you are done, show that the Coke bottle has almost emptied.  Now proceed to crumple the paper cone (or open it up revealing each page) to show that the liquid has
vanished.
You are provided with clear instructions for this effect and two others that can be done with the GHOST BOTTLE. 
VERY WELL MADE PROP.
