If you want to add ice cubes to the glass; add them before you pour any liquids into the glass.
Pour chilled orange juice into a large glass.
Pour in chilled soda.
Gently pour grenadine. It will sink to the bottom and give that layered look.
Add some whipped cream on top, an orange slice to the side of the glass and a maraschino cherry on top.
Stir before drinking.
