Squeeze one trigger and follow the mist from its nozzle

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

Show one prepared hand sprayer producing a brief mist above an empty tray. The finger pulls the existing trigger once while the bottle remains upright; a small spray begins at the original nozzle, spreads outward and then stops. Follow the source and the expanding region together so a drifting cloud cannot substitute for a visible spray event.

This original brief is untested. Use a plain water sprayer already set to a visible mist pattern. The task covers one short squeeze and release, not priming, nozzle adjustment, continuous aerosol operation or claims about droplet size. Keep the scene free of faces, cleaning chemicals and product-performance labels.

2. Authorized first frame

Use a photograph or accurate drawing you own or have permission to use. Show one upright sprayer, its existing hand grip and a finger resting on the trigger before the squeeze. Place an empty shallow tray below the intended spray region. Keep the nozzle tip exposed and the expected mist inside the frame.

Choose a side view with soft backlighting and a plain contrasting background. Separate the trigger silhouette from the bottle neck and leave clear air beyond the outlet. Avoid a pre-existing fog cloud, a cropped outlet or a hand covering the nozzle.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the complete prompt, check the available settings and cost estimate, then submit only when ready. This page supplies text; it does not upload an image or start a generation.

4. Prompt and timing

Start from my authorized image of one upright water sprayer held in the original hand, with the finger on its trigger and an empty tray below the exposed nozzle. Lock the camera and keep the bottle orientation steady. Pull the existing trigger inward once. During that squeeze, emit a brief fine spray only from the original nozzle opening. Show its narrow origin near the tip and a wider mist region farther along the same direction. Keep the nozzle attached and the tray below the spray. Release the trigger after the short stroke; stop new spray at the outlet while the already emitted mist continues forward and becomes less distinct. Retain a clear air region around the bottle. No second squeeze, floating source cloud, solid laser beam, rotating nozzle, spray through the bottle wall, added hand, camera move, cut or droplet-size text. End with the trigger released and no continuing emission.

Establish the trigger, exposed tip and clear air before motion; confirm the tray is below the planned spray path.
Use the middle of the clip for one squeeze. Compare the narrow outlet region with the widening mist farther away.
Release and inspect the ending separately: emission stops at the tip, while previously emitted mist can remain briefly visible.

These beats are author suggestions, not exact model timing guarantees. Adapt their proportions to the clip length actually available.

5. Inspect the output

After inspecting your own output, record a time or frame, visible observation and pass, fail or inconclusive judgment for each condition. A convincing ending alone does not verify the preceding action.

The same trigger moves inward and returns without changing the bottle shape.
The first visible spray is connected to the original nozzle opening.
The spray region widens away from that opening rather than appearing as an isolated cloud.
New emission ends after the single squeeze; existing mist does not freeze in place.
Bottle, nozzle and tray remain coherent in the fixed view.
If lighting hides the outlet origin, mark source continuity inconclusive.

6. Fix one failure

A fog cloud appears first: begin with clear air and tie the earliest mist to the exposed tip.
Spray becomes a solid rod: request dispersed mist with visible background between droplets, without adding a beam effect.
The source follows the finger: assign emission to the nozzle and keep trigger motion separate.
Spraying never ends: shorten the squeeze and add a distinct release beat before the final view.
The mist is invisible: improve contrast in the authorized input rather than inventing a colored chemical or opaque smoke.

7. Ending and limits

End with the original sprayer upright, trigger released and no fresh mist leaving the nozzle.

Save your own generated result through the available result controls, together with the authorized input, exact prompt, settings and inspection notes.

No H3 output, atomization test, pressure measurement or spray-product recommendation is supplied. Visibility depends on lighting and background; a rendered cone cannot establish droplet sizes or a real spray distribution.

A dispenser pump delivers a connected dose into a dish. This task instead follows an expanding airborne spray and separates the end of emission from the later disappearance of emitted mist. Unlike the pouring task, the bottle stays upright and no pouring stream is requested.
