Start by filling a clear glass or a mason jar with ice cubes to keep the drink chilled.
Slowly pour the lemonade into the glass, filling it about one-third of the way.
Next, carefully pour the blue sports drink over the back of a spoon or down the side of the glass to create a layered effect. Fill the glass until it is two-thirds full.
Finally, repeat the layering process with the cranberry juice, pouring it gently to maintain the layers. Fill the glass to the top.
Garnish with fresh strawberries and blueberries on top, and add a mint leaf for a refreshing touch if desired.
Serve immediately with a straw or a spoon to mix the layers before drinking.
