Place sugar, Jello-O and Kool-Aid in a large bowl. Add in the hot water and whisk until everything dissolves. Add in the cold water and whisk to combine.
Fill popsicle molds half way with mixture. Freeze for 45 minutes if using small molds, you want the mix to be half way frozen so it might take longer for the size of mold you are using. Just don't let it freeze the whole way.
Break up ice crystals with a toothpick, sprinkle with Nerds, about 1 teaspoon. Let freeze for another 45 minutes or until solid. Fill almost to the top with more liquid. Sprinkle with Nerds again, add popsicle sticks and freeze until solid. Serve and enjoy! It might be hard to remove popsicles, if so, dip into hot water to loosen.
