Show a tube designed with a cow on the front - open it up so it can be seen that there is nothing inside of it. Also display photographs of various milk bottles, in various colors. An audience member selects one of the colors. Magically, a bottle of milk in that same color appears in the tube. This is repeated several times, with audience members selecting a color, and that exact color of milk bottle magically appears. Finally, after all the colored bottles have been put on display, the tube is opened once more - this time to reveal a glass! Audiences love this effect!
This miracle warms the hearts of your audience and magnifies the energy of their souls.
