Pour 1 cup of water into a small saucepan and sprinkle 2 packets of unflavored gelatin over the water. Warm over low heat, stirring for about 3–5 minutes until dissolved. Remove from heat and mix in half of the sweetened condensed milk.

Incorporate vanilla vodka into the gelatin mixture. Set aside half of the mixture for the final layer. Pour the remaining mixture into shot glasses, filling them about one-third full. Place in the refrigerator for at least 30 minutes.

Pour in 1 cup of water and sprinkle in the last packet of unflavored gelatin in a separate saucepan. Heat over low flame, stirring until dissolved, about 3–4 minutes. Add orange Jell-O powder and mix.

Stir in fresh orange juice into the dissolved orange Jell-O mix. Pour this mixture over the set white layer in shot glasses. Chill until firm, about 1 hour.

Add a few drops of yellow food coloring to the reserved white gelatin mixture. Pour this yellow mixture over the now-firm orange layer in shot glasses. Refrigerate for an additional 2 hours.

Top each Jello shot with candy corn for a festive touch. Serve chilled.
