Pour 1 teaspoon of the orange sanding sugar with 1 teaspoon of the bat candy confetti sprinkles into a shallow bowl, and mix together. Brush honey or corn syrup onto the rim of your glass. Turn your glass upside down, at a 45-degree angle, and dip glass rim into the sugar-candy mix. Gently move the glass around the sugar, rotating the glass as you go.
Lift glass out of sugar. Tap off excess. Turn glass right-side up and repeat process. If there are empty spots, it means there was not enough moisture on the rim. To fix, simply dab glass rim with syrup and dip again in sugar mix.
Add vodka and black Sambuca to a cocktail shaker with ice. Shake well and strain into your garnished martini glasses and serve.
