In a small saucepan, bring 1 cup water to a boil. Add Jell-O mix and stir until dissolved.

Turn off heat and stir in a cup more water and the whiskey.

Place 16 plastic shot glasses on a baking sheet and pour in mixture until each is two-thirds full.

Refrigerate until set, about 2 hours. Top each with a dollop of whipped topping and gold sprinkles.

Place a rainbow candy belt on top, forming it into a semicircle like a rainbow, before serving.
