Muddle the blackberries in the bottom of a shaker. Fill the shaker ⅔ full with ice. Add the pomegranate juice, Chambord, vodka, lemon juice, and simple syrup. Shake the mixture until jet cold (about 20 seconds).
Stain the drink into a cocktail glass and add a garnish of blackberries on a pick. For dramatic effect add a few small pieces of dry ice, but be sure to let the dry ice dissolve before drinking.
