Write a Shorts script built around the loop, not the story arc

You are writing a YouTube Shorts script. Shorts run on a separate feed from long-form video, ranked primarily on completion rate and rewatch rate rather than absolute watch time, which changes the actual structural goal here: the aim is not "a satisfying story" the way a long-form script would be, it's a loop a viewer watches all the way through and then watches again without deciding to.

CONCEPT
A quick demo showing a $4 kitchen gadget doing something that looks impossible the first time you see it

TARGET LENGTH
30 seconds

SOURCE MATERIAL
Existing footage of a citrus peeler tool removing an entire orange peel in one continuous spiral in under 4 seconds

HOOK ANGLE
Open on the peel already halfway off, before revealing how — creates a 'wait, how' reaction instantly

LOOP RULES
The first line spoken or shown on screen must be understandable with zero context and must create tension that only resolves by watching to the end — a viewer scrolling past has under one second to decide whether to stop, so there is no room for a setup sentence before the hook. The final frame or final line must connect back to the first one, either by literally repeating a visual or phrase from the opening, by leaving a detail unexplained that only makes sense once re-watched from the start, or by ending mid-motion in a way that flows naturally back into the opening frame — the goal is that a viewer who reaches the end has a reason to let it loop rather than swipe away, since a rewatch counts as additional watch time on the exact same piece of content instead of requiring a new view to be earned from scratch. Cut every line that does not directly serve the hook or the loop's setup and payoff — a Shorts script has no room for a scene-setting aside, a tangent, or a joke that doesn't advance toward the loop point; if a line's absence wouldn't change whether the loop works, cut it. Front-load the single most visually or verbally interesting moment as early as physically possible without spoiling the loop's payoff — waiting past the first three seconds for the best moment assumes a level of patience the format does not reward. State on-screen text only where it adds information the voice or visual doesn't already carry, since Shorts are frequently watched muted or half-attended, and both channels — audio and visual — should carry the core point independently, not redundantly.

OUTPUT FORMAT
1. The script as a numbered sequence of beats, each with an estimated duration in seconds, spoken or on-screen text, and a one-line visual direction.
2. One line explicitly stating the loop mechanic — exactly what connects the last beat back to the first.
3. Total runtime, confirmed to be under the target length.
