Boil 2 cups of water, then mix with lime jello and unflavored gelatin in a bowl until dissolved. Pour into shot glasses and refrigerate for 20 minutes.

Combine 1 cup boiling water with sweetened condensed milk. Hydrate 2 envelopes of gelatin in cold water, dissolve in 3/4 cup boiling water, and mix with the milk.

Once the lime layer is set, gently pour the creamy mixture over it, filling two-thirds full. Refrigerate for another 20 minutes.

Prepare the orange layer by boiling 2 cups of water, mixing in orange jello and gelatin until dissolved. Cool slightly before pouring over the creamy layer.

Chill the shot glasses in the refrigerator for 20 minutes until completely set.

Garnish each shot with whipped topping and sprinkles before serving.
