Boil the 1 cup water as you empty the green jello powder into a medium-sized bowl and assemble your shot glasses.
Pour the 1 cup boiling water into the powder and whisk until fully dissolved.
Carefully add the 1/2 cup vodka and 1/2 cup cold water.
Pour the jello liquid into a measuring cup and then distribute evenly amongst the shot glasses.
Refrigerate for 2-4 hours before serving.
To add a sugar rim, carefully run the lip of each glass under cold water (holding the shot glass upside down) and then dip the glasses into a small dish filled with the gold sugar crystals.
Garnish with a dollop of whipped cream and a sprinkle of gold pearl candies.
