Easy watermelon popsicles

INGREDIENTS:
1 pound watermelon
2 tablespoons sugar
2 tablespoons lime juice

PREPARATION:
Cut the watermelon into small chunks (discarding the rind), and put them in a blender with the sugar and lime juice. Process until smooth, adding enough water (or fruit juice) so that the mixture liquefies. Pour into popsicle molds, and freeze.
