In a large pitcher, pour in 4 cups of water and 1 cup of freshly squeezed lemon juice. Add 1 cup of granulated sugar, then stir thoroughly for about 2-3 minutes until the sugar dissolves completely, creating a refreshing lemonade base.

Next, carefully sprinkle in 1 teaspoon of activated charcoal powder into the lemonade mixture. Use a whisk or a wooden spoon to stir vigorously for about 1 minute until the lemonade achieves a striking deep black color.

Gently pour in 1 cup of soda water while simultaneously stirring the mixture lightly. Aim for a quick but gentle motion to preserve those lovely bubbles.

As your Witches Brew Lemonade fizzes away, grab a cutting board and slice fresh lemons into thin rounds for decoration.

Fill tall glasses with ice to chill your potion. Carefully pour the Witches Brew Lemonade over the ice, filling each glass to about three-quarters full.

Artfully place lemon slices on the rim of each glass. Then, add a playful twist by nestling a few gummy worms or candy eyeballs atop the drink.
