After your eggs are ready to go, it’s time to find some small containers and get your Kool-Aid packets ready to go.
This is really all you need, because Kool-Aid has citric acid in it. No need for vinegar! Add one packet of Kool-Aid to 2/3 cup of water and stir. That’s it. I used both lukewarm and cold water and it didn’t really make a difference with how our eggs turned out. Keep in mind that Kool-Aid powder is pretty messy, so you should do all of the mixing over your sink to prevent your counter tops from turning different colors the next time you wipe them off. (Not that this happened to me or anything.)
You don’t have to leave the eggs in the dye cups very long before you’ll see them become quite brightly colored. The eggs will smell fruity at first but after they dry, they smell and taste like normal hard-boiled eggs.
