While waiting, gather all the ingredients for the red layer, and let's start mixing.
Dissolve 1 box of red Jell-O in 1 cup of boiling water.
Stir in ½ cup vodka and ½ cup cold water.
Once the white layer is set, carefully pour the red mixture on top, filling to the brim. Refrigerate for another 2-3 hours or overnight for best results.
Right before serving, top each Jell-O shot with a dollop of whipped cream. Add a pinch of red, white, and blue sprinkles for a festive finish.
