You can purchase popsicle molds at a kitchen supply store, or even a grocery store during the summer season, and of course online. However, you can also make your own!
Fill miniature paper or plastic disposable cups, leaving at least 1/2 inch of headspace. Place on a sheet pan and cover tightly with aluminum foil. Poke wooden popsicle sticks into the center of each cup, halfway down. The foil should keep the sticks in place. Freeze for at least 2 hours until solid. When ready to enjoy, remove foil and peel the paper cup away or run plastic cups under hot water for a few seconds to loosen pops. And enjoy!
