Prepare the blue layer: In a mixing bowl, dissolve the blue raspberry-flavored gelatin mix in 1 cup of boiling water. Stir until fully dissolved, then add 1 cup of cold water and 1/3 cup vodka. Mix well.

Pour the blue gelatin mixture into clear cups or shot glasses, filling each about one-third of the way. Refrigerate for 1-2 hours until set.

Prepare the white layer: In another mixing bowl, sprinkle 1 cup of unflavored gelatin over 1 cup of boiling water and stir until dissolved. Add 1/2 cup sweetened condensed milk, 1 cup cold water, and 1/3 cup vodka. Mix well.

Carefully pour the white gelatin mixture over the set blue layer in each glass, filling another third of the glass. Refrigerate for 1-2 hours until set.

Prepare the red layer: In a separate bowl, dissolve the strawberry-flavored gelatin mix in 1 cup of boiling water. Stir until fully dissolved, then add 1 cup of cold water and 1/3 cup vodka. Mix well.

Gently pour the red gelatin mixture over the set white layer, filling the final third of each glass. Refrigerate for 1-2 hours until fully set.

Optional garnish: Top each shot with whipped cream and sprinkle with red, white, and blue sprinkles for a festive touch.

Serve chilled and enjoy responsibly!
