metaphor exercise…what am i?

i seep from the hood of the mangled steel skeleton, leaving my body behind.

i have become amorphous, leaking from the orifices of a dying engine.

oil has pooled on the pavement in an impenetrable black hole.

the metal frame turns cherry red, magma from a caldera, deep and sizzling.

then, shooting through the tailpipe at lightspeed, i burst into the air in an opaque, noxious cloud.

i envelop the bodies that pass through me, coating them in a thick metallic must.

glowing cinders ignite within the wreckage, foreshadowing plumes of fire.

it doesn’t matter; i’ve sprung loose from my prison.

hot and reeking, my molecules expand to fill their new home.

i sublimate from a liquid to a gas and i slip away into the sharp, chilled air.
