Cut watermelon vertically into 1 inch thick slices.

Use a small star cookie cutter to cut out star shapes from the flesh of each watermelon round.

Thread 7-10 blueberries into the center of each bamboo skewer, leaving enough space at the end for someone to be able to comfortably hold it, and a space at the top for the watermelon star.

Place the watermelon star on top and set the fruit sparklers on a serving tray. Cover and refrigerate until ready to enjoy.
