  • Do NOT add the missing 50 articles, i'm working on that.
  • Upload the thumbnails of articles that don't have them. (Download them from HERE and then click 100x in the table below. Then upload, making sure to add the file to Category:What If? Images.
  • Populate the two columns Book and YouTube (You don't need to own the books to help! The book chapters are already on this page: What If? chapters. Simply move what's already there, like this:

YouTube:

{{yt|YTNUMBER|YYYY|MM|DD|YTLINK|VIDEOTITLE}}

EXAMPLE:{{yt|2|2022|12|31|https://www.youtube.com/2LSyNhb5Y|What if everyone pointed a laser at the moon?}}

Books: For the first book:

{{book1|CHAPTER-NUMBER}}

For the second book:

{{book2|CHAPTER-NUMBER}}

EXAMPLE:{{book2|69}}
  • Keep improving the explanations, they're mostly still too short!
  •  ✓ Done  - Re-add all the hyperlinked article titles. They were removed by the AI which that did every other improvement.

We kept the chairs for five years but despite laborious attempts it couldn't be reproduced." This... isn’t actually a question, but thank you for sharing!

But what about the edge of ultracentrifuges, or generator turbines that have been running for years, for example?" The Mariner 1 has traveled much farther than Voyager 1.

Intense enough to cause a medium sized nuclear explosion. Better to just carry a sign.

Balloon Car.png Balloon Car "My 12-year-old daughter is proposing an interesting project. She is planning to attach a number of helium balloons to a chair, which in turn would be tethered by means of a rope to a Ferrari. Her 13-year-old friend would then drive the Ferrari around, while she sits in the chair enjoying uninterrupted views of the countryside. Leaving aside the legal and insurance difficulties, my daughter is keen to know the maximum speed that she could expect to attain, and how many helium balloons would be required." A balloon just big enough to lift you would be pushed down by the wind, and a balloon big enough to counteract that would lift up the car along with you. The way to achieve this result is parasailing.
