Nestlé bars filled with tiny bubbles

AEROS

Think of a chocolate bar with a light, airy texture that shares its name with a prefix meaning "air" in Greek.

This clue points to "AEROS," a line of chocolate bars made by Nestlé that have a light, bubbly texture inside. The word "filled with tiny bubbles" hints at the "aero" part, which comes from "aerated," meaning full of air pockets. It’s a straightforward reference to the brand name, with no hidden wordplay—just a description of what makes these bars unique.
