5 small packages of Jello (I used cherry, grape, blueberry, lime and lemon)

4 1/2 tablespoons of unflavoured gelatin

1 can sweetened condensed milk

Mix the cherry Jello with 1/2 tablespoon of gelatin. Add a cup of boiling water and stir to dissolve. Cool to room temperature and pour into whichever container you want your rainbow Jello in. Refrigerate until firm, about 20 minutes. Meanwhile, mix the can of sweetened condensed milk with 1 cup of boiling water. In a bowl, sprinkle 2 tablespoons of gelatin over 1/2 cup of cold water and let bloom for a couple of minutes then add 1/2 cup of boiling water to dissolve. Stir well, add to the milk mixture and mix thoroughly. Cool to room temperature before pouring over the first layer of Jello. Refrigerate until firm. Repeat the first step with the remaining jello while alternating with the milk mixture. Let the Jello firm up completely, then slice and serve!
