Practical Engineering explains Mechanically Stabilized Earth, where layers of reinforcement make soil strong enough to hold heavy loads, shown with a sand structure supporting a car. It notes that MSE walls are everywhere in infrastructure.
Why Hacker News points people here: Often named as a great first video from Practical Engineering and as the explanation of reinforced earth.

“Practical Engineering has a great video on this simple but pervasive technology.”
Great explanation of mechanically stabilized earth, a simple pervasive technology.
I wonder if sheets of a cloth-like material could be used in loading similar to Mechanically Stabilized Earth Practical Engineering has a great video on this simple but pervasive technology. this video
“Practical Engineering: -- -- Great first video”
Suggested as a great first video from the Practical Engineering channel.
I keep a Google Document of these to share just in case people ask about my YouTube interests. I Actually Watched All of Them I have actually watched ALL of the videos on these channels and I don’t even feel bad about it :-) I actually like new videos from some of the ones below (like NativLang, for example) but they maybe don’t hold up in the early videos. - Space Time: PBS Physics, sooo good -- link -- Great first video: link - Lindsay Ellis: Really, really intelligent video essays about film and culture -- link -- Great First Video: link - Periodic Videos: Chemistry, including a video for every element -- link -- Great first video (obviously): link Other Math and Science - 3Blue1Brown: Amazing math visualizations -- link -- Great first video, how e^pi*i works: link - NumberPhile: Fun math videos -- link -- Great first video: link - PBS Eons: Biology! -- link -- Great first video: link - PBS Infinite Series: Math math math, really really hard math -- link -- Great first video: link - SciShow: Science!

“Reminds me of reinforced earth which I learned about from this video”
Explains reinforced earth, where the commenter learned about it.
Reminds me of reinforced earth which I learned about from this video: this video (which is also from the pretty great Practical Engineering channel).
“Practical Engineering: Mostly Civil Engineering”
Listed as a civil engineering channel among favorites.
Ooooh, these are nice. Here are mine: Extra History: stories of historical incidents — link Real Engineering: mostly materials science — link - Wendover Productions — mostly transportation - link Tom Scott: a bit of everything — link - Jay foreman: Urban planning and maps — link The Engineer Guy: Manufacturing — link Practical Engineering: Mostly Civil Engineering — this video 3Blue1Brown: Math, visualized to me more intuitive — link
“It reminds me of the video”
Related demonstration of sand reinforced to hold a car.
It reminds me of the video "Sand Castle Holds Up A Car! - Mechanically Stabilized Earth" - this video
“Ha! just looked up the video”
Shows reinforcement increasing shear strength of sand.
I was suprised to see the use of wiremesh in sand castle building some years ago. Same concept though. You add something that helps with shear strength and you can build much taller sand buildings. It’s really counter intuitive to see too, since the sand could clearly sieve through the mesh. Ha! just looked up the video, seems it’s another practical engineering video I was thinking of this video
