Ingredients
🌴 Ingredients:
For the Float Base

How to Make Rainbow Island Float
Step 1: Chill Your Glass
Place your tall glass or float glass in the freezer for 10–15 minutes. This will create a frosty effect that enhances your drink’s presentation.

Gently pour lemon-lime soda over the top of your layered mixture. Watch as it foams and bubbles, creating that magical floating effect!
