With this great cocktail accessory you can create a perfectly layered cocktail at home. Full instructions are included along with great cocktail ideas. Basically you pour in the heaviest liquid (usually a syrup) then place the Rainbow tool over the top of your glass and lower the middle stem. Pour in the next liquid so that it gently cascades over the tool settling neatly on top of the first layer. Repeat until you are ready to serve. Packed in a smart gift tube.
