Metaphor for romantic potential (6)

I believe the answer is:

sparks

(Other definitions for sparks that I've seen before include "Flashes from electrical discharge" , "Fiery particles emitted by fire" , "Electric discharges" , "Bright discharges" , "Fiery particles for informal electrician" .)

I've seen this clue in the USA Today.
