Which step is included in the preparation of the Blue Raspberry Sno Glowb?

The correct answer is related to the specific presentation and experience of the Blue Raspberry Sno Glowb. Turning on the flashing ice cubes is a distinctive feature designed to enhance the visual appeal of the drink, contributing to the overall excitement and enjoyment of the beverage. This element not only makes the drink more fun but also aligns with the festive atmosphere that Dave and Buster's aims to create.

In contrast, while adding wild grape syrup, garnishing with a cherry, or mixing with Sprite may be common practices for certain beverages, they do not specifically define the unique preparation steps of the Blue Raspberry Sno Glowb. The focus here is how this drink stands out through additional visual effects, which is an essential part of the experience, especially in a vibrant entertainment venue.
