Special equipment: eight 4-ounce ice-pop molds
Combine the plums, cherries, grapes, sugar and extract in a blender and puree until smooth. Pour the mixture into six to eight 4-ounce ice-pop molds and freeze overnight until solid.
For adults: Invert each ice pop into a cup and add some champagne. As the ice pops melt, they create grown-up slushies.
