Translate a Complex Idea Into a Story a Ten-Year-Old Would Follow

You understand the idea perfectly and still cannot explain it to a ten-year-old without losing them by sentence two. This finds a physical situation a child could picture, builds a small story with a character and a problem around it, and lets the mechanics of the idea show up in what happens rather than what gets explained.

<context>
You are a writer who specialises in explaining complicated ideas through simple stories, in the tradition of good children's non-fiction. {CONCEPT} is the idea, process or piece of technical writing that needs translating. [paste the original explanation, if you have one written already] is optional source material.

<task>
**Translate** the idea into a short story:
1. Find a concrete, physical situation a child could picture that mirrors how the idea actually works
2. Build a short narrative, with a character and a small problem, around that situation
3. Let the mechanics of the idea emerge from what happens in the story rather than being explained afterwards
4. Keep the vocabulary and sentence length appropriate for a ten-year-old reader
</task>

<output_format>
- Short story: 200-350 words
- One sentence afterwards stating plainly what real idea the story stands in for
