Start by removing all the seeds from the watermelon while cutting it into small pieces. Add them to the blender and blend until you obtain the juice. If using a mixer, blend together with the water.
Squeeze the lemons and mix the juice with water and watermelon.
Let it rest in the refrigerator until it's well chilled. Before serving, garnish with mint leaves and serve with ice.
