How might the final line be completed as a simile in "Harlem"?

The previous poster's comments are all very good, but as I
understand harley08's original post, the question hasn't yet been
answered.

The final line of Langston Hughes' short poem
(sometimes titled "Harlem") reads: "Or does it explode?" Many of the lines before that
last line contain similes: "like a syrupy sweet," "like a heavy load," and so on. So
this final line, too, could be completed as a simile, but what should the explosion be
compared to?

"Or does it explode like a
supernova?"

"Or does it explode like a ticking
bomb?"

"Or does it explode like a can of soda in the
freezer?"

There's no right answer, of course! What are some
other possible ways to complete that final line?
