In Katy Perry's song "Firework," the figurative expression employs a simile, comparing one's emotional state to a drifting plastic bag in the wind.
How to explain
The lyrics evoke a sense of aimlessness or feeling lost, paralleling the bag's directionless movement to the sensation of lacking purpose or direction.
Yet, the subsequent line, "Do you know that there's still a chance for you," suggests hope and potential within oneself, akin to a spark igniting a firework.
This comparison symbolizes inner strength and resilience, encouraging individuals to recognize their latent potential despite moments of feeling adrift, inspiring them to shine brightly like a firework.
