# MiniMax H3 bubble-release prompt: detach one bubble from a fixed ring

Extend an already bulging soap film slightly and detach one bubble from its ring. The task follows a single visible connection becoming a single separate object.

Original synthetic practice still, not a generated result. No model run has been performed.

## Generator

Use MiniMax H3 base image-to-video. Turn on Add end frame to expose First Frame, upload first-frame.png only, and leave Last Frame empty. Fast requires a pair and is not covered. Choose only options offered by the current interface; opening it does not submit.

## Starting state

The original illustration shows a teal wand with a large circular ring, a pale film bulging to the right and a short connecting neck. The background is plain, with no face, mouth, soap brand or claimed real surface physics.

Keep the wand handle and ring center fixed. Follow the film neck at the ring opening and keep the emerging bubble singular throughout the short action.

## Steps

1. Start with the existing bulge, not an empty ring. This isolates release from the separate actions of dipping a wand and blowing air.
2. Keep the detached travel short and do not request a bubble cloud or a pop. The separation should remain large enough in frame to inspect.
3. Pause before neck closure, just after detachment and at the ending. A bubble simply appearing beside the wand does not show the required connection-and-release sequence.

## Acceptance

- The wand and ring remain stationary and keep their original shape.
- One bulge remains connected by a visible narrowing neck before release.
- Exactly one bubble separates from that neck without duplicating.
- The detached bubble remains fully visible and unburst in the ending.

## Limits

This is a schematic topology-continuity exercise, not a surface-tension simulation, fluid measurement or tested H3 bubble effect.
