1. Add about half a bottle of red edible glitter into orange juice and shake well to combine.
2. Add purple edible glitter into cran-grape juice and shake well.
3. Pour the glittery juices into molds and freeze until solid.
4. To serve, pour champagne over the frozen juice cubes. The cubes will keep the drink chilled and slowly release juice and sparkles as they melt. Cheers!
