Confetti Jello

     4 (3 oz) boxes Jello in assorted colors/flavors

     4 c boiling water

     4 envelopes unflavored gelatin

     1 1/2 c hot water, divided

     1 can (14 oz) sweetened condensed milk

     1/2 c water

Dissolve 1 box of Jello in 1 c boiling water.  Pour into 8 x 8" pan (or simlar) and chill until firm (2 hours is adequate).  Repeat for remaining Jello flavors.  In a 2-cup measuring cup, sprinkle unflavored gelatin over 1/2 c hot water.  Let sit 5 minutes.  Add remaining 1 c hot water and stir until gelatin is dissolved.  In a 1-qt measuring cup, stir condensed milk with 1/2 c water.   Pour gelatin mixture through a sieve and add to condensed milk mixture.  Let sit until cool (room temperature).  Cut flavored Jello into small cubes and toss gently in a 9 x 13" pan.  Add condensed milk mixture to cubes.  Chill until firm.  Cut into serving size pieces (we like to cut into 1 3/4" pieces because they fit nicely in serving cups).
