Remove the crowns from the strawberries and wash them thoroughly.
In a blender, combine the strawberries, water, lemon juice, and agave nectar. Blend until completely smooth.
Pour the mixture into popsicle molds, leaving a little space at the top for expansion. Insert popsicle sticks.
Place the molds in the freezer and let them set for at least 6 hours or until completely frozen.
Once frozen, run the molds under warm water for a few seconds to help release the popsicles. Serve and watch them disappear!
