A battery everyone owns, rebuilt as a tiny cannon with a lit fuse. Familiar brands make the odd build readable, and the flame says it is about to fire. You click to see whether it works. The bare title leaves the image to do everything.

Remix this
When you transform an everyday object, keep its brand label visible so the before-state reads instantly. Show the moment just before the payoff, fuse lit, not the payoff itself.
