Start by shaving 16 ounces of shaved ice into a cup or bowl. Create a dome shape on top by using a dome shaper or by rotating your wrist as the ice is shaved. Beginning on the left side pour in a straight line of cherry (or any red) syrup, covering about 1/3 of the ice. Next, pour Blue Raspberry (or any blue) syrup on the right side in a straight line, covering another 1/3 of the ice. Finish by filling the center section with Banana (or any yellow) syrup. Overlap the yellow syrup slightly with the red and blue syrup to create the rainbow. With only three flavors, you will have five vibrant colors! Serve with a spoon or spoon-straw.
