Foamless Cups

For stadium cups and drive-through restaurants.

Why pay your employees to stand around and wait for the foam to go down? Foamless cups have a micro-thin layer of shortening one inch in width around the inside of any cup, and located 1/2 inch from the top of the cup. Thus, when the foam hits the shortening, it breaks the surface tension of the foam, causing it to instantly release itself, and thus fills perfectly well without any foam.

       Does that work? Or would you just get a cone of bubbles in the middle - which would be just as effective, I guess. (Have neither beer nor shortening on hand to test it out.)

       Welcome to the Bakery!   

       BTW, what's 'shortening'?
FloridaManatee, Apr 01 2003
  

       Shortening: hydrogenated vegetable oil, used in cooking. High cohesion and adhesion as fats go.

Problem: if you stack these cups before use, won't some of the shortening adhere to the outside of the cup above? Unless the layer is somehow indented from the inside surface.

       How about designing an automatic foam-blower-offer built into the beverage dispenser?

       [supercat], that sounds like a chindogu to me. Link.
