flashes in the pan

Short-lived promising things

Flashes in the pan are things or people that show initial promise but fail to deliver lasting results.

The phrase comes from flintlock firearms, where gunpowder in the pan might flash without igniting the main charge—a spectacular start with no follow-through.

The band had one hit single but turned out to be flashes in the pan.
