Inflate one balloon with a single visible pump stroke

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

1. Task and boundary

Push down the plunger of a small hand pump connected to one partly inflated balloon. Let the existing balloon envelope expand modestly while its neck stays on the nozzle. End after one stroke with the hand and plunger stopped and the same balloon visibly larger.

This original scene is untested. Use a prepared connected balloon and one short stroke. Exclude pressure targets, capacity claims, popping, detaching the nozzle and an empty membrane appearing only after pumping starts.

2. Authorized first frame

Prepare a photograph or accurate drawing you own or have permission to use. A simple pump body rests on the table, its plunger raised and the original hand on its handle. A partly inflated balloon is already attached to the visible nozzle.

Choose a side view that shows plunger travel, nozzle-neck contact and the whole balloon outline together. Leave clear expansion space around the balloon. Use one small surface mark to track the same envelope without adding printed text or a complex design.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the prompt; check settings and cost before submission. Nothing runs automatically.

4. Prompt and timing

Begin with my authorized image of a stationary hand pump, its raised plunger under the original hand and one partly inflated balloon attached to its nozzle. Lock the camera, pump body and table. Push the same plunger downward once through a short visible stroke. During that stroke, let the existing balloon envelope expand modestly as one connected surface. Keep its neck seated around the same nozzle and its small surface mark attached as the surrounding membrane enlarges. Preserve the original balloon shape family without replacing it with a different balloon. Stop the hand and plunger at the end of the stroke and hold the larger balloon. Do not inflate before the push or shrink the pump to imply growth. No second stroke, burst, detached neck, second balloon, camera zoom, pressure readout or cut.

1. Establish, first fifth: identify the raised plunger, attached neck and initial envelope outline.
2. Pump, middle three fifths: compare downward plunger movement with gradual balloon expansion.
3. Hold, final fifth: stop the stroke and inspect the larger connected balloon beside the unchanged pump.

5. Inspect the output

For each check, record a frame or time, observation and pass, fail or inconclusive judgment.

• One downward stroke is visible while the pump body stays fixed.
• The balloon enlarges during the stroke rather than appearing afterward.
• The neck stays continuously attached to the original nozzle.
• The marked envelope expands without producing a second surface or balloon.
• The final pump size is unchanged beside the larger balloon.
• If the nozzle junction is hidden, mark attachment continuity inconclusive.

6. Fix one failure

• The balloon swaps shape instantly: retain its initial contour and expand gradually.
• The whole scene grows: anchor pump and table dimensions against fixed references.
• The neck detaches: expose the nozzle junction throughout the stroke.
• The plunger cycles repeatedly: request one push followed by a final hold.
• The envelope bursts: reduce the requested expansion and end sooner.

7. Ending and limits

Finish after one stroke with the same larger balloon still attached to the unchanged nozzle and pump.

Save your result, authorized input, exact prompt, settings and inspection notes.

No H3 generation, pressure measurement, leak test or inflation guarantee is supplied. The visible stroke and shape change do not verify the pump internals or balloon capacity.

The bubble-release task separates a film from its ring. This balloon keeps its neck attached while an existing closed envelope expands in response to one visible pump stroke.
