Let the vodka soak into the watermelon overnight by cutting a small hole in the top of the melon and inserting the open vodka bottle into it. Bend a coat hanger into a loop, and insert the end of the loop into the chuck of a cordless drill. Use the loop to pulverize the interior of the watermelon. Add the simple syrup and lime juice and continue to blend until the mixture is smooth. Insert a spout and pour over ice into a glass. Garnish with a lime wedge.
The only way to improve on a boozy watermelon is to bring a power tool into the mix. This is a cool, refreshing watermelon drink that would make MacGyver weak in the knees. The technique allows you to make a melon full of delicious aqua fresca. Sure, it takes 24 hours to make, but just imagine being the guy at the cookout that makes a drink with a drill, and then starts walking around topping up people’s glasses straight from the melon! That guy knows how to party.
