37.8M views in 18 seconds: how to make “why is it like that?” 3D explainers with Claude

A step-by-step guide to the 18-second 3D explainer: one everyday object, one small mystery, and a see-through model that answers it. Why a reel about a tape measure hook passed 37 million views, the Claude prompts for the questions and the 3D model, and how postreadygo posts one every day at the best time on every platform.

Why is the hook on a tape measure loose? An 18-second reel answers it with a see-through 3D model, and it has more than 37 million views. The account behind it has about 20,000 followers.

The format, and why it works

The account we looked at is @seethroughworks (See Through Works) on Instagram: 114 posts and about 20K followers as of November 12, 2026. Its bio says it “opens up the objects you use every day: locks, zippers, kettles, seatbelts, engines.”

The three parts of the format.
  • The question is something you have noticed and never asked. Everyone has wiggled that hook.
  • The answer fits in one sentence. The hook moves by exactly its own thickness, so the tape reads true both ways.
  • See-through 3D shows the inside without a single word of jargon.
  • 18 seconds means people watch it twice, and send it to someone.

What Claude is and how to get an account

Claude is an AI assistant made by Anthropic. It can research, write scripts and prompts, and write the code that draws an animation in your browser.

  1. Go to claude.ai or install the Claude app.
  2. Sign up with your email address or your Google account.
  3. Type your first message in the box at the bottom.

Step 1: Claude finds the questions

Questions prompt

Give me 30 “why is it like that?” questions about everyday objects for 20-second explainer reels.

- Things people have noticed but never looked up
- The answer must fit in one or two sentences
- For each: the question, the answer, and the source I can check

Check every answer against its source. A wrong explanation gets corrected in the comments within minutes.

Step 2: Claude builds the 3D model

3D model prompt

Build a single HTML file with three.js, vertical 1080x1920, 20 seconds.

- A tape measure with a hook that slides in and out by its own thickness
- Make the body see-through so the mechanism is visible
- Show it hooked over an edge, then pushed against a wall, with “0” lining up both times
- Short captions at the bottom, two or three words at a time
- A Record button that downloads the video

Open the file in Chrome and press Record. If something looks wrong, tell Claude what you see and it fixes it.

Why posting by hand holds you back

  • Five apps, five uploads. The same video, the same caption, again and again for Instagram, TikTok, YouTube, Facebook and Threads.
  • The wrong time. You post when you remember, not when your audience is online.
  • One busy day breaks the streak. Then two, then a week, and the account stops growing.

With postreadygo, one message to Claude schedules a whole month: one video a day, each at its best time, on every platform at once. That is 30 posts a month per platform, without opening a single app.

Step 3: Connect postreadygo to Claude

  1. Go to postreadygo.com and click Get started for free. Then open Linked and connect Instagram, TikTok, YouTube or any other supported network.
  2. In Claude, open Settings, then Connectors, then Add custom connector.
  3. Name it postreadygo and paste: https://www.postreadygo.com/mcp
  4. Click Connect, sign in to postreadygo and press Allow.
  5. Test it: “List my postreadygo accounts.”
