Dope Tech Episode 2

<<@BrockToews says : Once I left a bottle of water in the car during winter and it supercooled like this. Upon drinking some it froze in my mouth. Super bizarre sensation>> <<@BenPilcher-l9t says : Hope to see more videos on this subject in the future.>> <<@nsTurkish says : Turkish subtitle please>> <<@Jolfgard says : People will insist that supercooling needs almost clear water, yet I get consisted results with goddamn fizzy, sugary lemon soda. What am I fundamentally doing wrong?>> <<@stanleyyuan1572 says : As a biomedical researcher this is an amazing explanation for why we can freeze things like cells and viruses without worry. Thanks guys!>> <<@LFTRnow says : A bottle 10 nm in size... so the new shrinkflated containers at the store then.>> <<@felasho says : Can you do a video about balloons? PS: Please Pin me!>> <<@Nerviqo says : Water that refuses to freeze? That’s basically the Elsa version of passive-aggressive. ❄😅>> <<@akifunmc says : So how do I supercool myself without creating ice crystals? Asking for a friend.>> <<@Neria-Mangofretchen says : wouldn't a hypothetically infinitely rigid container work at any size when filled completely with water since even the tiniest ice crystal forming would push against the container which can't expand?>> <<@rhratrahraty9379 says : I can make all this more intuitive in a 3D explainer video for you. Just don't know how to contact you, Anyone got an email or something, I won't have access to social media cuz I'm crazy for wanting to keep my privacy. Any other means of communication with these people?>> <<@briand8090 says : Question. What if you had a sphere of ultrapure water floating in the vacuum of space? What would happen between the competing forces of the lack of pressure bringing down the boiling point and the lack of particles for nucleation? Is it possible that the water would remain liquid?>> <<@mrmoshpotato says : Add! Booze!>> <<@MatthewBester says : I think with shrinkflation we will achieve these sizes of bottles within four years.>> <<@Agisek says : Well that solves cryogenics then. All we gotta do is cut a person into 20nm cubes, put them into rigid containers, number those of course, I'm not playing puzzle with a human body again, and then freeze them. No crystals anywhere to be seen, no damage to the tissues and cells.>> <<@thejuice027 says : Add heat! There, answered the question without watching the video.>> <<@bestsnowboarderuknow says : It's not called super cooling... It's called Otter Pops.>> <<@joostvhts says : Super cool!>> <<@phyzixlab says : Would love to see an explanation why the crystals form when the bottle is smacked>> <<@robotnikkkk001 says : .....HOW TO STOP WATER FROM FREEZING?.... *_WARM IT??!!_* .....HEEHEEHEEHEEHEEHEE>> <<@LuderBudde says : Too fast explained>> <<@goskascience says : It has been 2 days. Why is this video still not on Nebula?>> <<@MogR91 says : o.o super cool! (muahaha accidental pun) but now I wonder, does this have anything to do with trees surviving freezing winter days?>> <<@seanrodgers1839 says : Opening a beer bottle at just the right temperature and it freezes all of the way down as you watch forlornly>> <<@megayao456 says : Pressurised water? Sparking water!!!>> <<@1LoveGame2 says : I bought a used refrigerator/freezer combi for 10 bucks that actually supercools my drinks. For some reason the freezer part only freezes the bottomhalf of the products. But when i put a drink in there it doesn't freeze at all only if i hit the bottle it instantly freezes up. Best 10 bucks i've ever spend :D>> <<@melkiy582 says : Just add salt>> <<@mera6479 says : I was sceptical but I gave the book The ADHD Balance by Lentlish a try. Now I’m doing more in a day than I used to in a week.>> <<@Aleksandar_Lukic says : Excellent video as always, but there is no thing such as "cold temperature" 1:33.>> <<@CaritasGothKaraoke says : Response to title: “keep it warm”>> <<@wolpumba4099 says : AI Summary *Abstract:* *Understanding Supercooled Water: From Instant Freezing to Unfreezable States* This video delves into the fascinating phenomenon of supercooling, explaining why water can remain liquid below its freezing point due to a delicate balance between the interior's desire to freeze and the surface's resistance to formation. It then introduces a more extreme state: water that becomes impossible to freeze. This is achieved by containing supercooled water within extremely tiny, rigid vessels. In such small spaces, the pressure generated by the slight expansion of even a minuscule ice crystal becomes so significant that it suppresses further freezing, overriding the crystal's natural tendency to grow. This unique property has promising implications for cryogenics, particularly in preventing cell damage caused by ice crystal formation. I used gemini-2.5-flash| input-price: 0.3 output-price: 2.5 max-context-length: 128_000 on rocketrecap dot com to summarize the transcript. Cost (if I didn't use the free tier): $0.0056 Input tokens: 13048 Output tokens: 670>> <<@Whalebelly2239 says : Fantastic, now we just need to figure out how to shrink humans and cryogenic chambers are a reality!>> <<@AlexSchendel says : Not on Nebula?>> <<@theCodyReeder says : Smacking the bottle adds tiny air bubbles. the energy/pressure has nothing to do with it. notice how it froze from the top where there was air? I have a short video on my channel where I showed my cat that smacking a bottle with no air doesn't freeze.>> <<@liamshiels8626 says : Can you have supercooled non-water liquids? Supercooled molten metal, For example?>> <<@ZetaFuzzMachine says : Supercool>> <<@pikminlord343 says : Good video>> <<@sghfmrd says : How to stop water from freezing? Just use salt lol😂>> <<@ralfbaechle says : A 200 nm bottle of water, now that's what I call shrinkflation!>> <<@WordLightDotNet says : CLICKBAIT! Good luck trying to "STOP" water from freezing at zero Kelvin.>> <<@S3l33ngrab says : I love how you can see the ice form around the air bubbles at the end of the video>> <<@mn-ru4li says : Don't put water in the freezer. Done. You're welcome. No need to slap anything.>> <<@aarongold7220 says : easy, raise its temperature!>> <<@Italianjedi7 says : Supercooling can be used for cryogenics?!>> <<@Kenjitsuka says : Cool!>> <<@GCLgrowls says : This video was super cool.>> <<@carllindgren7130 says : (:>> <<@stoatystoat174 says : 🥰💙>> <<@yjlee97-z9o says : Detective Conan claimed that you can freeze a bottle of sports drink to the supercooling state if you wrap it up with a towel and place it carefully. Did anyone try to make it?>> <<@Schoko4craft says : Melting ice takes a lot of energy than just raising the liquid waters temperature by the same amount. Doesn't that mean this supercooling crystallization also needs to cool a lot before it's possible to crystalize all at once?>>
