The bulb looks completely ordinary, and that is the trick. If the cake can pass for a real bulb, she has already won, so the plain object becomes the boast. Her wide eyes underneath ask the same question as the title, can it light up.
How the packaging works
Title
The title sets the challenge and adds the twist, a cake that works.
Thumbnail
The thumbnail shows the target object looking so normal it doubles as the boast.
Remix this
When your skill is making one thing pass for another, show the finished piece looking perfectly normal. Ordinary is the proof. Save the reveal, the cut, the glow, for inside the video.
The transferable lesson
When faking is the skill, ordinary is proof
