A red and blue cocktail to celebrate the new spiderman movie!!
Put a tall glass in the freezer for about a minute or 2.
While the glass is chilling, take a ball spoon, scoop out 2 half balls of watermelon. Place the 2 half balls together to make 1 ball of watermelon, then stick a toothpick through them and place in the freezer. Or you cut just cut the water melon into small cubes, stick a toothpic through them and place in the freezer.
Mix the blue Curacao, lime juice and water together in another glass or a ramekin.
Once your tall glass is nice and chilled, take it out of the freezer and then add your grenadine.
Add the blue Curacao mixture very slowly.
Garnish with the watermelon and then serve with a straw.
