Dope Tech Episode 2

<<@veritasium says : For the first 100 people who sign up, I will personally offset the first month of your carbon footprint on Wren: https://wren.co/veritasium>> <<@DatHuynh-m3w says : Why?>> <<@RubenStormMusic says : After all the abstract physics videos, watching someone get buried in actual liquid rock somehow feels like the most Veritasium move possible.>> <<@lennycampagna734 says : Unfortunately i have to say oxygen is particularly useful if your chest is actively being compressed to the extent that you cannot actually move your lungs 😂>> <<@alfredo3623 says : He wont sink in the concrete while wearing a full body life jacket?>> <<@williammolla3591 says : Thanks for explaining. I used to be a welder and one of our contracts was fabricating forges for a company called SouthWestern Portland Cement. I always wondered why they needed forges and why it was a company in Ohio was called Portland Cement.>> <<@Dave_Crupel says : 49:37 Well played, Nick. Well-played.>> <<@athenapaine7533 says : was it hot in the bowl?>> <<@JohnTarsoly says : There's a video about concrete somewhere explaining how there's so much concrete in the cites in the Northern hemisphere like Asia and US, it's effecting the wobble of the Earth's rotation.>> <<@sousedsoused1836 says : Dude, I can't believe you sat there in the immoveable shere of concrete immobility while that ginormous decapitation slide sticking out of the cement truck. Coulda lurched and popped off your noggin>> <<@ilvirtop1396 says : 12:53 even you misspoke😭>> <<@AlexPPS25 says : You were wrong at minute 1 + ~10s, out of 500kg of concrete, you can not fill up 2 cubic meters, but rather 0.2. 1m³ in it's standard receipe weight's around 2300kg. (Without added water or other additives). No hate, maybe just an unseen fault of yours😂>> <<@MeganEllis-EESS says : Yup. Thats my job. All that testing man. All me. That concrete break was a type 5.>> <<@rapzid3536 says : Why would they drive around with pop instead of just sugar?!>> <<@huizhang9311 says : Pls explain how spiral escalators work>> <<@Xuani76 says : Content is great, but it has an unbearable amount of ads....will not watch any more videos in this channel>> <<@iqa5i says : ❤❤>> <<@jacksondrumfoster says : 20:55 Bill Wurtz reference. Very good>> <<@iansclone says : 1:03 I work in estimating for a commercial construction subcontracting company. Until I took this job, me either. It's staggering.>> <<@Rob_Reviews_Leftism says : Had to throw that BS about evolution in there huh?>> <<@WollumbinWarning says : The Pyramids were definately partly made by Geopolymer... Please investigate.>> <<@Treehouseink-BD says : 21:30 why did he get air balled so bad>> <<@ucfj says : Next time please explain bullet ballistics while getting shot>> <<@Ublomor says : RIP to that nice Aqualung dry suit>> <<@Ublomor says : Forgot to say that the Romans also used to heat the "malta">> <<@eisbar7681 says : bro is so cute when hes smiling.... we don't build long time structures anymore. it's easier for us to destroy and rebuild and destroy and rebuild even if its technically not easier... we have weird morality when it comes to sustainability.... we lost all morality when it comes to sustainability 😂 money is the only thing that matters. we buy cheap plastic instead of good material. we actually waste a lot of money with this weird technique....>> <<@eisbar7681 says : having an extra oxygen supply doesn't make much sense when the actual problem is when you breathe out, cement is going to fill up the gap so you can't breathe in anynore... our lungs inflate and deflate and inflation isn't possible when there isn't enough space because it disappeared. but good luck?😂 have fun? I guess. . Wish i could paint this whole congrete ball🤩🤩>> <<@AI537-n6w says : If that starts rolling, will his neck be strong enough to stop it?>> <<@Brooks-videogames_39452 says : 0:40 cocaine?>> <<@RichardMaster-fj6me says : Very interesting>> <<@laurensdebonnet6030 says : 0:35 watching him ruin a 1900$ drysuit :(>> <<@asiwasb4 says : Thanks for the conversion to metric, wish you did all throughout the video. 10:57>> <<@Loaxmc says : What scares me the most is the thought of a substance 3 times heavier than water pressing on your balls>> <<@עדוצדוק-כ1ה says : In 00:22 seconds it’s look like you having poop>> <<@Jonas-wk8sf says : Thank you for this beatiful video>> <<@NeevIyer says : 21:30 doesn't the guy touch the wet concrete?>> <<@atomicsquirt8082 says : 8:50 now we have clankers. Smh.>> <<@joeyzagari4155 says : Cool, can you talk about LC3 concrete in offsetting carbon emissions>> <<@fyremonte says : Idea. If you do episode that busts scientific myths (like Mythbusters) and explain the science that bust or supports. Just thinking.>> <<@AREA51AI-Reality says : And now try to swim... 😂>> <<@StanTrnik says : What about hemp cellulose and glass/carbon fiber from wind turbine blades mixed in to concrete? You should explain that and bust the myths about wind turbines and silly wood use in different products.>> <<@MillardFeelmore says : $3,000 dry suit, gets in concrete...... I hate this video solely based on that. Still love you though!>> <<@MechaDupek says : I used to repair concrete in college. If you ever have to mix cement or make concrete locally with a portable mixer, don’t get the dry cement powder on your skin. If you do, your sweat will activate the cement and you will get chemical burns.>> <<@WunHungLo99 says : Break the clear container? Better than dying....>> <<@Remy.S7 says : you are intra ball =)>> <<@manda3dprojects966 says : I though he would wait it until it's turn dry and solid concrete and what if he wants to poop or pee?>> <<@izhilin says : 7:00 Impressive! They still use freedom units for testing!>> <<@riiiicc says : Stupid question: can you recycle concrete?>> <<@UnparalleledSpoof says : Only 2 cubic meters of concrete, for every man, woman and child doesn't seem enough. I can't share that... It would be better if it were for each man, woman and child>> <<@davidcopola3783 says : 10:55 The aggregate limestones or bluestones being required to have closer to spherical shape to yield the maximum strength of the concrete cannot be true. The belief may be coming from the fact that the spherical shape has the lowest surface area to volume among most shapes and the spherical shape is considerthe most stable and strongest shape in nature, hence the reason planets a spherical. However, in concrete the surface area also matters that comes in contact with the cement. Therefore, odd, elongated and uneven aggregate shapes are the most preferred aggregate piece shape to yield maximum strength in many concrete applications. It also depends on the chemical bond strength of the particular type of cement.>>
