In a large heat-safe pitcher or mixing bowl, combine the Jello mix, Kool-Aid packet, and sugar. Carefully pour in 2 cups of boiling water and stir until all the powders are completely dissolved. This may take a minute or two—make sure there are no grainy bits left.

Once everything is dissolved, stir in 2 cups of cold water to bring down the temperature and help the mixture set properly.

Slowly pour the mixture into your popsicle molds, leaving a little space at the top for expansion. If your molds come with sticks, insert them now.

Place the molds in your freezer and freeze for 4 to 6 hours, or until fully solid. For best results, freeze overnight.

To remove the popsicles easily, run the mold under warm water for a few seconds and gently pull them out.
