Any fan here????>> <<@Makarious-s5l says : 8:38 reminds me is some other files>> <<@senchatf says : >> <<@NavghanbhaiThakor-j9c says : This channel is underrated I will definitely recommend this.>> <<@noneya4705 says : Wow! A brass key won't scratch it. Try some steel or tungsten>> <<@noneya4705 says : Humans didn't invent glass. Nature did>> <<@berelliminor8838 says : I hope this channel is getting paid for all these ad breaks. Its 1 per chapter. Not even joking. Btw love the channel. But thats alot of ads. And its not normal for your channel its this one video. Its weird.>> <<@mcdonals_master says : i just want to say "Superfest">> <<@HansPedersen-p1f says : The full context of why it was on the iPhone so fast is because they stole and hijacked the innovation from a Swedish company working on this. I think that legal battle is still ongoing, two decades later. Also, the first 3 generations of iPhone technically used two layers with an airgap between. As they couldn't figure out how to bond LCD directly to the required cover glass. The first phone with only one layer of glass was the Samsung Galaxy S2, using AMOLED.>> <<@김민정-j5n5j says : 😮>> <<@AntWhisperer says : 04:39 what do you mean we have been using glass for a million + years??? Our species hasn’t even existed for a million years.>> <<@ulvschmidt7174 says : i think most glasses nowadays are plastic though.>> <<@cliffcox7643 says : 19:36,, sometimes women say this to men.>> <<@thyongamer says : TLDR. Glass will still break. It’s not unbreakable. It’s very strong yes, but all their tests are head on flat drops. So, if the phone gets hit on the screen edge that’s it - it just breaks.>> <<@hevyjameshulleza461 says : Basically star trek is right. Transparent aluminum is real.>> <<@johnattwood8467 says : Who heard Leeloo Dallas at 8:24😅>> <<@Alena-s1l5o says : 21:54 this is not because of an imperfect glass technology, it is purely bc it’s an iPhone 😂 my android Chinese phone has been thrown to the ground at least a thousand times in five years and there is no single scratch on it. My new iPhone, on the other hand, got some accidental scratches in only six months, so…>> <<@thefceUSMC says : Give that Gorilla glass sample to my kid and it will shatter by him just putting it in his pocket. How do I know this? He has shattered at least 10 gorilla glass screens in the last 6 years. He told he doesn't know how it happens, he only knows that he pulls the phone out of his pocket and presto, chango it's shattered.>> <<@JulianPelletier-d9n says : 20:27 to 20:38 - why not try submerging the glass into a solution of FrNO3 instead of KNO3? I'm no chemist, but it sounds like replacing Na (sodium) with K (potassium) works because they both have a single electron in the outer shell and also K is larger than the Na. So my thinking is that Francium might be even better because it also has only one electron in its outer shell, but it's even bigger than K !>> <<@linnmyat6229 says : Best Gorilla Glass Ads ever>> <<@bradfowler6464 says : I had a Samsung S23, in an aluminum case, with a protective screen protector. I got out of my car, the phone fell out of my pocket, from the height of a car seat...the protective screen AND the screen shattered. Badly. While I was waiting for the packaging for the warranty exchange, I was getting little bits of glass in my pocket, hand, side of my face, etc. So, I don't believe those tests, even one iota!!! Totally 🐂 💩>> <<@mkontent says : So much bs in the video. Hardly any progress was made since ion exchange and that wasn't even invented by Corning.>> <<@noneofyourbusiness6269 says : glassovich you're a russian spy>> <<@wallhopxpro says : Thers a glass 1 atom thin>> <<@alucide says : A short story about phone screens. Phone people: we need strong glass for phone Glass people: here you go, strong glass Phone people: this is so strong, we can make it thinner for more profit Phone glass breaks. Phone people: we need stronger glass for phone Glass people: here you go, stronger glass Phone people: this is so strong, we can make it thinner for more profit Phone glass breaks.

Phone people: we need stronger glass for phone Glass people: here you go, stronger glass Phone people: this is so strong, we can make it thinner for more profit Phone glass breaks.>> <<@sigexaura says : How come you blurred out the Apple symbol on the back of your phone but there have been plenty of other symbols including apple symbols that you have not blurred out please reply with an answer>> <<@Daototo2 says : The need for GLASS is transparent.>> <<@THE-SMUZZ says : Glass is a liquid bro its been proved, its a million year melting liquid, its disorganized, and it was always a liquid just slow to prove it, you should edit and update>> <<@matthewmathis62 says : Jesus loves you, Derek. And you were made by Him. There is a very important story about what He did for you (layed down His life to pay for yours). He is always listening. ...why don't you talk to Him? He oftentimes answers through His Word (known as the Holy Bible).>> <<@depdava1 says : Awesome! How dose the touch sensitivity thing work? Next Vid.>> <<@tihzho says : Petr is really goofy lol>> <<@evermore9291 says : Transparent aluminum. We ever get cost down . . .>> <<@ahokezo9179 says : I've already watched this. Why is it showing me as a new video???>> <<@Cerbera66 says : The first nearly indestructible glass was invented in East Germany in the late 1970s. It was called ‘Superfest’ and was intended to be sold in the West to generate foreign currency for the GDR. They used – or rather invented – the same mechanism that is used today for Gorulla glass: replacing the sodium ions on the glass surface with potassium ions. Dieter Patzig and his team applied for a patent for this in 1977. So Gorilla did not invent it themselves.>> <<@williamdiaz7965 says : Most important material EVER made is PLASTIC. Gemini: It’s hard to argue against that. If you look around whatever room you're in right now, it’s practically guaranteed you are surrounded by it. Before plastic, we relied almost entirely on wood, metal, glass, and stone—materials that are heavy, expensive to harvest, and difficult to shape into intricate forms. Plastic completely broke that bottleneck. It redefined global manufacturing, healthcare, and consumer life. But like many of humanity's greatest inventions, it has a massive double-edged sword. Here is a look at why it holds that "most important" title, alongside the massive environmental footprint it leaves behind: --- ### The Synthetic Revolution Before the early 1900s, everything was natural. If you wanted a billiard ball, someone had to hunt an elephant for ivory. If you wanted insulation for electrical wires, you needed shellac (which is refined from a literal bug secretion). When Leo Baekeland created **Bakelite** in 1907—the first fully synthetic plastic—he unlocked a material that was a total shape-shifter. It was lightweight, durable, electrically non-conductive, and could be molded into virtually anything. ### Why It Changed the World * **Modern Medicine:** Sterile, single-use medical equipment—like IV bags, syringes, artificial heart valves, and sterile packaging—dramatically reduced cross-contamination and saved millions of lives. * **Global Logistics:** Because plastic is incredibly lightweight, substituting it for heavy glass or metal packaging drastically reduces the fuel required to transport goods around the planet. * **Accessibility:** It democratized consumer goods. Electronics, food storage, and everyday tools became cheap and accessible to billions of people. --- ### The Catch-22: Form Follows Breakdown The exact reason plastic is a miracle material is also why it's an ecological nightmare: **it doesn't degrade.** Nature doesn't know what to do with petroleum-based polymers. A plastic bottle doesn't decompose; it just breaks down into smaller and smaller pieces called **microplastics**, which have now been found everywhere from the deepest trenches of the ocean to human tissue. > **The Paradox:** We invented a material designed to last for hundreds of years, but we primarily use it for single-use products designed to be thrown away after 5 minutes. So while it might be the most functionally important material we've ever engineered, it also represents our biggest engineering challenge: figuring out how to undo or replace it before we're entirely buried in it.>> <<@Qagpt says : They don’t want to do 100 percent uncrackable. If they do they don't have repeated customers>> <<@gavoserch says : 8:24>> <<@SHAQUEELA02 says : Wow technologia>> <<@judgedayan9934 says : Did anyone ever tell you, you look like the English golf pundit, Rick Shiels?>> <<@mrpicky1868 says : "photon just passes right though" statement as incorrect as it can possibly be>> <<@Krish_gadara says : 🗣️The greatest material thar ever lived>> <<@harshbarj says : Obsidian brittle? Na. You just need a diamond pick.>> <<@treeguyable says : Hey Chuck, they burned Venice down again, whadaya say we banish them to that island out there?>> <<@treeguyable says : I have had cell phones for decades, back when people still had pagers. Never cracked a screen. I make my own pouches that hold the phone, with a caribiner attached to my belt loop. It is not as " cool" as having it in your back pocket, but, never sat on it, or broke the screen while it was just " swinging" from the caribiner.>> <<@timfries139 says : If Gorilla Glass is so great, why does every phone today need a case and screen protector?>> <<@JEL260 says : Yo where my Superfest heads at?>> <<@matthewkite5110 says : I believe the "width" of a blade. Is called the "Kerf or Kief?"....>>
