1. In a blender, puree the diced watermelon until completely smooth and liquified—no chunks should remain.
2. Strain the watermelon puree through a fine-mesh sieve to remove any pulp or fibers for the silkiest texture.
3. Stir in the fresh lime juice and mix well—taste and adjust balance as needed.
4. Fill tall glasses with 2 generous scoops of vanilla ice cream each.
5. Pour the beautiful pink watermelon-lime mixture over the ice cream, letting it cascade around the scoops.
6. Top off with chilled lemon-lime soda, pouring slowly to prevent excessive foaming.
7. Garnish with fresh mint leaves for cooling aroma and beautiful presentation.
8. Serve immediately with long spoons and straws for the perfect float experience!
