Add watermelon, strawberries, lime zest, and lime juice to a blender.
Taste and adjust the flavor here, adding more lime or a touch of sweetener, as desired.
Pour the pureed fruit into popsicle molds, cover with a lid (or foil) and insert wooden popsicle sticks. Freeze popsicles 3-4 hours, or until very solid.
, remove the lid and run each well of the popsicle mold under cold water for a few seconds. Gently wiggle the popsicle stick side to side to help loosen the popsicle from the mold. (If it’s not budging, just run it under cold water for a few more seconds and try again)
