Place some of each fruit into the popsicle molds. Be sure to place some fruit directly against the sides of the mold.
Pour in the fruit juice until each mold is almost filled. (This leaves a little room for the stick/base.)
Add the popsicle sticks or reusable popsicle bases into the center of each mold.
Freeze for at least 5 hours to overnight until the popsicles are set.
Remove popsicles from the mold and enjoy immediately. If you have a little trouble getting them loose, run the bottom of the mold (where the popsicle is) under warm water for 10 seconds and try again.
