Place your Jello cups onto a shallow baking tray.

In a medium saucepan, boil 1 cup water.

Remove from the heat, and whisk in pineapple jello mix.

Stir until dissolved.

Stir in ½ cup cold water and ½ cup whipped cream vodka.

Divide the jello among your plastic cups, filling about ¼-⅓ full.

Move the cups to the refrigerator to chill for 2 hours.

For the next layer, bring 1 cup of water to boil in a medium saucepan.

Remove from the heat and whisk in orange jello mix.

Stir until dissolved, then add ½ cup cold water and ½ cup whipped cream vodka.

Allow the orange jello to cool completely before pouring evenly into your plastic cups, filling to about ¾ full.

Move to the refrigerator to chill for another 2 hours.

For the last layer, in a medium saucepan, whisk together 1 cup water and 1 envelope of knox gelatin.

Heat on the stove until it is hot and steamy, no need to boil.

Pour in sweetened condensed milk and whipped vodka, and whisk.

Allow this mixture to cool completely, then finish filling the jello shots with this layer.

Move them to the refrigerator for another 2 hours to chill.

Before serving, top with whipped cream and a candy corn.
