Fill a small cocktail glass with ice. Pour your choice of cranberry juice (for a black widow Halloween cocktail) or pulp-free orange juice (for a spooky screwdriver) over the ice. Gently layer black vodka over juice.
Skittle Bombs: take bottles of unflavored vodka and packs of skittles, pick a skittle color and put them all in a bottle, shake until they dissolve, freeze to chill before serving - These are so good! Approximately 10 skittles per ounce of vodka.
