Squeeze fresh lemon and lime (or blood orange) juice into a bowl.

Stir in activated charcoal powder or a few drops of black food coloring until the mixture turns a spooky dark black.

Pour in cranberry juice, black grape juice, and a splash of pineapple juice. Stir well.

Add sweetener to taste, such as sugar or agave syrup, and stir until combined.

Slowly pour in soda water or sparkling water. Stir gently to keep the bubbles.

Lightly mash the berries and add them to the mixture or individual glasses.

Fill glasses with mashed or frozen berries. Pour in the black lemonade.

Add spooky garnishes like gummy worms or a lemon slice. Drop a small piece of dry ice into each glass right before serving for a dramatic smoky effect.
