In a medium sized bowl, add the water, and sprinkle the Gelatin on the top, and allow it to bloom, following the directions on the package.
Stir well to blend.
Add the Vodka, and stir again.
Divide the Gelatin into three smaller bowls. In one bowl, add the Light Blue Food Coloring Gel.
In one of the other bowls, add the Sweetened Condensed Milk, and in the last bowl, add the Blue Food Coloring Gel. Fill the shot glasses 1/3 full with the Blue Gelatin, and place in the refrigerator for 1 hour, until the Gelatin has set up. After the Gelatin has set, remove from the Refrigerator, and add the Light Blue Gelatin, filling another 1/3 of the shot glass, making it 2/3 full.
Place the shot glasses back in the Refrigerator for 1 hour to set the Gelatin.
Remove the shot glasses from the refrigerator, and fill the rest of the way with the White layer, and place back in the Refrigerator for at least 2 hours.
When ready to serve, sprinkle on the Snowball M & M's to decorate.
Serve, and Enjoy!
