It exploded.

A man in a red shirt and blue shorts stands in a grassy yard, holding a long, red firework that emits smoke and sparks; he swings it back and forth, then drops it to the ground as it continues to smoke. The scene cuts to a distant view of a large explosion in a city, seen through a black metal railing with heart-shaped cutouts, with a massive plume of smoke and dust rising into the sky.
