Here's a cute idea! If you like to dye eggs with the kids, instead of buying those dying kits, use kool-aid. One pack of Kool-aid and 2/3 cups water and you've got awesome egg dye. Two bonuses: it's cheaper than those boxes of egg dye and it smells great!!
*Side note: if you use the lemonade flavor, mix it with a little bit of orange to get a better yellow color, otherwise it's too light.*
