To begin, you'll typically have a shot glass with one or more ingredients, such as cherry liqueur and grenadine, ready to go. In a separate glass, you'll fill it halfway with the mixer or energy drink, like Red Bull, that complements the shot. The excitement starts when you hold the shot glass containing the ingredients just above the second glass. With a swift and confident motion, you'll drop the shot glass into the second glass. As the two liquids combine, you'll often experience a burst of flavors and effervescence that creates a thrilling taste sensation.
