A great new effect that takes the Jastrow Boomerang illusion to something which can be validly performed in a modern age. The magician shows two coffee cup sleeves from their local deli, one for a Venti and the other for a Grande. To the spectator, the Venti is clearly smaller than the Grande (as it should be?) but as the magician shows this is just marketing, in fact, the Venti and Grande can be the same size or in some cases, the Venti is larger than the Grande, and simply by turning the sleeve over to change the label can make the difference.
