Runtime: 1:00

Description: Rods from God.

This is the nickname for a theoretical space weapon, in which large rods of tungsten would be dropped onto Earth based targets.

The idea behind this weapon is that the projectiles would build up enough speed, and thus kinetic energy, which would cause bomb-like destruction on the ground below.

The concept was devised during the Cold War but has faced heavy criticism both logistically and scientifically.

However, it has certainly made its mark on science fiction, both appearing in and being referenced across many media, from TV to video games.

But could it work in practice?

We tested to find out.

Description: I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there.

The first time I heard about shade balls the claim was they reduce evaporation.

But it turns out this isn't the reason they were introduced.

Title: Why do planes fly so high?
Runtime: 1:04
Date posted: 1 year ago
Description: Now, it’s true that one of the benefits of flying at 30,000 ft is a smoother ride. This is high in the troposphere, the layer in which most weather occurs. So, there’s less turbulence and fewer storms to navigate around.

But this is not the main reason that planes fly so high.

How A Student's Question Saved This NYC Skyscraper

Correction: From construction images of Citicorp, sharp-eyed viewers might see that the mid-V columns are still there. Those columns help prevent buckling of the diagonal and the weight of people on the floor above, but do not take the majority of the gravity load. So we left them out of our diagram to clearly explain the load paths. See page 70 of this source for more details - https://drive.google.com/file/d/1ODFo66-_V7Y9vKANbj53mQ0z20RZ2Uai/view
