For each flavor, dissolve one box of jello in one cup of boiling water. Pour into a container and chill
until firm. Don't do anything with the sweetened condensed milk and unflavored gelatin yet.
After chilling the jello cut it into small blocks. Carefully mix the blocks in a 9 x 13 pan.
In a separate bowl, sprinkle 2 envelopes unflavored gelatin into 1/2 cup cold water. After the gelatin blooms, add 1 1/2 cup boiling water and dissolve. Add the can of condensed milk. Stir and cool. Pour cooled milk mixture over jello and chill overnight.
Cut into blocks or shapes and serve!
