Fill popsicle molds (or cups if using) 3/4 way full of fruit of choice. Pour coconut water into molds and fill the rest of the way. Place molds in freezer. Allow popsicles to freeze completely before serving, about 5-8 hours. Once your popsicles are ready to serve, run the bottom of the popsicle molds under warm water to help release them from the molds.
