This is a new trick and a cool trick too! In fact the material supplied is a utility item that can be used in various ways to create a wide range of effects. Of course do not use it more than once in the same show.
Effect: Here is an example of what can be done with this instrument. You show a white fancy looking vase and a cylindrical cover. The cover is just a cylinder with both ends open and can be seen right through. Pour some colorful liquid syrup in the vase and cover it with the cylinder for a moment. Utter some magical words, if you prefer to do so, and then remove the cover. Will it not be quite surprising to see that the syrup has changed into mouth-watering chocolates? In a similar way you can change milk to ice cream or flowers to a garland! Everything is automatic
