This spooky Halloween mocktail is more fun for kids and adults when served in a large punch bowl with candy spiders and gummy worms. You can make this seasonal beverage fancier by adding cinnamon sticks.
Only add a small amount of dry ice to each cup, about the size of a large pea. Otherwise, the cups will overflow with bubbles. Allow guests to enjoy their beverage until it stops bubbling, and the dry ice has melted.
