In a large mixing bowl or pitcher, combine the tonic water and lemon-lime soda. Gently stir to mix without losing too much carbonation.
Add the fresh lime juice and agave syrup, stirring until well mixed.
Gradually sprinkle in the spirulina powder, stirring continuously to achieve a consistent green hue. Adjust the amount based on your desired color intensity.
Fill serving glasses with ice cubes. Pour the glow worm mixture over the ice until filled.
Garnish each glass with a handful of fresh blueberries and a few mint leaves.
Serve immediately and enjoy the mesmerizing glow brought by the tonic water!
