Abstract: A device for placement on the rim of a drinking glass to allow different fluids to be poured into the glass in such a manner that varied layered drinks can be easily and quickly made. The device includes a cup member for placement on the rim of the glass in such a manner that a substantially airtight seal is formed between the glass and the bottom of the cup member. A plurality of fluid passageways are formed in the bottom of the device to allow fluid to pass from within the cup member to the interior of the glass. The fluid passageways are angled downward and outward so as to direct the fluid passing therethrough substantially against the inner walls of the glass so that the fluid will run down the inner walls of the glass rather than merely falling or dripping onto the surface of any fluid already in the glass. In this manner, the incoming fluid will not break the surface tension of the fluid already present in the glass but, rather, will float on this fluid to create a varied layered drink.
