Follow a prepared siphon over its crest into a lower bowl

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

1. Task and boundary

Show a prepared transparent siphon transferring water from a higher vessel into a lower receiving bowl. The tube rises over the source rim before turning down to an exposed outlet. Keep the inlet below the source waterline and the outlet below that waterline throughout the short shot. Inspect the connected route instead of presenting the water as an unexplained stream between containers.

This original scene plan is untested and begins with an already filled tube and established flow. It does not teach how to start a siphon or specify a pressure calculation. Exclude mouth suction, pumps, a dry tube starting spontaneously and an outlet above the source surface. End before the inlet becomes exposed or the receiving bowl fills.

2. Authorized first frame

Prepare a photograph or accurate drawing you own or have permission to use. Show two open containers at different heights and one transparent bent tube already filled with water. Its inlet is visibly submerged in the higher vessel; its open outlet hangs over the lower bowl and clear of the bowl water.

Use a side view that includes both water surfaces, the tube crest and the entire downward leg. The tube needs support so its geometry stays fixed. Leave headroom in the receiving bowl and enough source water to keep the inlet submerged. Do not hide the crest behind a label or crop out the outlet.

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 an already flowing, water-filled transparent siphon between a higher source vessel and a lower bowl. Fix the camera, containers, tube supports and tube shape. Preserve the single connected route: submerged inlet, rising leg, crest above the source rim, descending leg and exposed lower outlet. Continue a modest stream from that outlet into the same receiving bowl. Let the source waterline gradually lower and the receiving waterline gradually rise while both container shapes stay unchanged. Keep the inlet submerged and the outlet below the source surface throughout. Retain water continuity through the visible tube; do not insert a traveling empty gap, create a second branch or let water cross a container wall. Do not tilt either vessel or introduce a pump, hand, suction action or hidden cut. End while the established flow still continues, before the source inlet uncovers or the bowl approaches its rim. No numerical flow claim or animated internal pressure diagram.

Opening: identify the submerged inlet, crest and lower outlet in the already flowing setup.
Middle: follow outlet-to-bowl continuity while comparing each waterline with a fixed container detail.
Ending: keep flow ongoing and both boundaries within their starting constraints; do not invent a spontaneous shutoff to create a still ending.

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.

One tube connects the source inlet, crest and outlet without a missing segment.
The inlet remains below the source surface throughout the visible interval.
The exposed outlet remains below the source waterline and above the receiving surface.
A visible stream starts at that outlet and reaches the lower bowl.
Source level falls and receiving level rises without added water or vessel deformation.
If glare hides the liquid inside the crest, mark internal continuity inconclusive rather than inventing a pressure observation.

6. Fix one failure

Water crosses open air at the crest: show the complete bent tube and retain its wall around the route.
The source level rises: keep the source and receiving roles explicit and compare their fixed references.
An air gap appears: simplify to an already filled tube and remove priming or startup language.
The tube bends during flow: add visible supports in the authorized input and fix their positions.
The outlet becomes submerged: increase initial receiving clearance or shorten the observed interval.

7. Ending and limits

End during continuing transfer, with a submerged source inlet, a readable crest and a lower exposed outlet.

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

No generated result, flow-rate experiment, pressure reading or practical siphon setup validation is supplied. The shot reviews visible routing and level changes; it cannot prove hidden pressure conditions or that an arbitrary real tube will maintain flow.

The connected-vessels task compares levels approaching one height through a connection. This task keeps an exposed outlet below the source surface and follows an already established route over a crest. It ends during transfer, not at an equal-level equilibrium.
