Cut the watermelon into cubes, removing any seeds. This will ensure a smooth texture in the popsicles.

In a blender, combine the cubed watermelon, lime juice, honey (or agave syrup), and coconut water (if using). Blend until completely smooth. This step is crucial for achieving a creamy popsicle texture.

Pour the watermelon mixture into popsicle molds, leaving a little space at the top for expansion as they freeze.

Insert popsicle sticks into the molds. If the mixture is too thin, let it sit for a few minutes until it thickens slightly before inserting the sticks.

Place the molds in the freezer and freeze for at least 4 hours, or until solid. This ensures that the popsicles hold their shape when removed from the molds.

To remove the popsicles from the molds, run warm water over the outside of the molds for a few seconds. This will help loosen them.

Enjoy your refreshing watermelon popsicles on a hot day!
