Pin this magical Ocean Water Punch recipe for your next under the sea party!
This classic ocean water punch is one of the most popular blue party drinks for a reason. It’s incredibly easy 3 simple steps, visually stunning, and a guaranteed crowd-pleaser for all ages. The vibrant blue color perfectly captures the ocean theme, making it a centerpiece for your drink table.

Ingredients

• 2 liters lemon-lime soda (like Sprite or 7UP)
• 1 (64 oz) bottle white grape juice
• 1 (12 oz) can blue Hawaiian Punch concentrate (thawed)
• 1-2 scoops blue raspberry sherbet or vanilla ice cream (optional, for froth)
• Gummy fish and rock candy swizzle sticks for garnish

Directions

1. Chill all liquid ingredients thoroughly before mixing to ensure the punch stays cold without excessive ice.
2. In a large punch bowl or drink dispenser, combine the chilled lemon-lime soda, white grape juice, and thawed blue Hawaiian Punch concentrate.
3. Stir gently to mix, being careful not to over-stir and lose carbonation.
4. Just before serving, add scoops of blue raspberry sherbet or vanilla ice cream. This creates a frothy, “seafoam” effect.
5. Garnish individual glasses or the punch bowl with gummy fish and rock candy swizzle sticks for an extra whimsical touch.

Pro-Tip: For an even deeper blue or to adjust sweetness without adding more sugar, you can add a few drops of blue food coloring to the punch. Always test a small amount first!

2. Whip Up a Delightful Mermaid Party Punch

Mermaid Party Punch magic in a glass! Save this recipe for enchanting party sips.
For a truly magical touch, this mermaid party punch uses layers to create a beautiful visual effect. These layered ocean drinks look complex but are surprisingly simple to assemble. The addition of edible glitter makes for truly sparkling sea drinks that will enchant your guests.

Ingredients

• 1 cup pineapple juice, chilled
• 1 cup blue raspberry drink syrup or Kool-Aid (prepared)
• 1/2 cup coconut milk or cream of coconut, chilled
• Ice cubes
• Edible glitter (silver or blue)
• Optional garnishes: mermaid tail cookies, fresh berries, lime slices

Instructions

1. Prepare your syrup: If using Kool-Aid, mix according to package directions and chill.
2. Layer the base: Carefully pour the chilled blue raspberry syrup into the bottom of each glass. Fill about one-third of the glass.
3. Add ice: Gently add ice cubes to each glass, being careful not to disturb the blue layer too much. The ice will help create a barrier for the next layer.
4. Create the middle layer: Slowly pour the chilled coconut milk over the back of a spoon, allowing it to gently flow over the ice and sit on top of the blue layer. This creates a creamy white layer.
5. Top with pineapple: Repeat the spoon-pouring technique with the chilled pineapple juice to form the top, slightly lighter layer.
6. Add sparkle: Sprinkle a pinch of edible glitter into each drink and give it a very gentle stir if desired, for a shimmering effect.
7. Garnish and serve: Adorn the rim with a mermaid tail cookie or add fresh berries for a final touch.

Pro-Tip: For the best layering effect, ensure all liquids are well-chilled and pour very slowly over the back of a spoon. The denser liquid (syrup) goes first, followed by less dense liquids.

3. Mix Up a Refreshing Blue Lagoon Mocktail (Kid & Adult-Friendly)

Cool, blue, and delicious! Pin this Blue Lagoon Mocktail for an easy party hit.
The blue lagoon mocktail is a fantastic choice for a versatile party drink. It’s a perfect non-alcoholic sea drinks option that both kids and adults love.

What You Need

• 1 oz non-alcoholic blue curacao syrup
• 4 oz sparkling lemonade or regular lemonade
• 2 oz lemon-lime soda (e.g., Sprite, 7UP)
• Ice cubes
• Garnish: Orange slices, maraschino cherries, Swedish fish candies

Instructions

1. Fill a tall glass with ice cubes.
2. Pour in the non-alcoholic blue curacao syrup.
3. Add the sparkling lemonade, stirring gently.
4. Top off with lemon-lime soda for extra fizz.
5. Garnish with an orange slice on the rim, a maraschino cherry, and drop a few Swedish fish into the drink for an authentic under the sea look. Serve immediately.

Pro-Tip: For an adult version, add 1.5 oz of vodka or white rum to the glass before adding the other ingredients. This transforms it into a delightful sea-themed cocktail while keeping the visual appeal consistent.

4. Create Shimmering Blue Seafoam Lemonade

Achieve enchanting seafoam perfection! Pin this shimmering blue lemonade idea.
This recipe for shimmering blue cocktails (mocktail version) is all about texture. The frothy ocean drinks effect is achieved with a simple meringue-like topping that mimics seafoam. It’s a light, refreshing, and visually delicate option that adds a touch of whimsy to your beverage table.

Ingredients

• 4 cups prepared sparkling lemonade, chilled
• 1-2 drops blue gel food coloring
• Ice cubes
• For Seafoam:
  • 1 large egg white (or aquafaba for vegan option)
  • 1/4 tsp cream of tartar
  • 1 tbsp powdered sugar

Instructions

1. Prepare the blue lemonade: In a pitcher, combine the chilled sparkling lemonade with 1-2 drops of blue gel food coloring. Stir until you achieve a light, oceanic blue hue.
2. Make the seafoam: In a clean, dry bowl, whisk the egg white (or aquafaba) and cream of tartar until soft peaks form. Gradually add the powdered sugar and continue whisking until stiff, glossy peaks form (like meringue).
3. Assemble the drinks: Fill glasses with ice cubes. Pour the blue lemonade mixture over the ice, filling about three-quarters of the glass.
4. Top with seafoam: Gently spoon a generous dollop of the prepared seafoam onto the surface of each drink.
5. Serve immediately to enjoy the frothy texture.

Pro-Tip: If using aquafaba (chickpea brine) for a vegan option, ensure it’s well-chilled and whip for longer than egg whites to achieve stiff peaks. This is a great way to offer allergy-friendly party beverages.

5. Craft Irresistible Shark Attack Drinks (with a Bloody Twist)

Unleash the fun! Pin this thrilling Shark Attack Drink for a dramatic party splash.

Instructions

3. Place a gummy shark on the rim of the glass, or float one in the drink if desired.

6. Garnish: For a dramatic effect, add a small piece of food-grade dry ice (handle with tongs!) to the punch bowl for a smoky, bubbling cauldron effect.

How do you make drinks look like the ocean with layers?

To make drinks look like the ocean with distinct layers, ensure all liquids are chilled and vary in density, pouring them slowly over the back of a spoon.

This technique is key for visually appealing layered ocean drinks like the Mermaid Party Punch.

Can I use natural food coloring to make blue drinks?

Yes, you can use natural food coloring to make blue drinks, primarily through ingredients like butterfly pea flower tea or spirulina powder. Butterfly pea flower tea brews a deep blue which dramatically changes to pink with the addition of lemon juice.

To keep under the sea party drinks cold for a crowd, utilize large drink dispensers with ice cores, make large ice rings with themed elements, or pre-chill all ingredients thoroughly.
