Science What-If
A "what if" question answered across scales: one sourced number per stop, every source on screen.
How it works
- 1Copy the install prompt and paste it into your agent.
- 2Your agent runs mo doctor to check Node.js, FFmpeg and Chrome, and tells you how to install anything missing.
- 3Give it your material. It renders an MP4 on your computer, and you ask for changes in plain words.
Paste into Claude Code, Codex, Cursor or any agent that supports skills.
All it takes
No API keyAny one of these is enough
- A spreadsheet or data
- A document, article or script
Dependencies
Node.js 22+, FFmpeg, Chrome. No API keys.
Before it starts, your agent runs mo doctor to check Node.js, FFmpeg and Chrome and tells you how to install anything missing; if this skill needs more (such as whisper for captions), its instructions say so.
Example prompt
Make a science what-if: what if all the ice on land melted? Use USGS, NOAA and Wikipedia, and credit every number.
Style prompt (Claude Motion or Opus 5.5)
Make a 36-second 16:9 science what-if for [who will watch, e.g. curious teenagers on our channel], playing [where, e.g. YouTube and Shorts]. Use only numbers from the sources below; a number worked out from a source must say "worked out from" on its tag, and keep every "about" and "would". Bright flat illustration: thick rounded shapes, a limited bright palette, soft long shadows, small people as scale markers. The question opens on a card over a small scene. One camera zooms from tiny to huge and back while four cards rise, each with one consequence: a big number with its unit, what it assumes, and a small source tag. Diagrams must be scientifically correct and say "not to scale" where they aren't. A closing card answers the question with the same qualifiers. End on a sources card listing every source, held 4 seconds. A curious vibraphone score with a whoosh on every zoom. Question: [e.g. "What if you dug a hole through the Earth?"] Consequences with sources: [e.g. "about 6,371 km to the centre — Wikipedia, Earth radius"] Answer line: [one sentence, e.g. "No one has dug it. With no air, the fall would take about 38 minutes."]
Nothing to install: paste this into Claude Motion (Team or Enterprise) or give it to Opus 5.5 for a similar look. The result changes from run to run; the skill works from your own material and renders on your computer.
