    I know I'm super late to the party, but I saw something that my initial explanation doesn't feel like it would work. At 5:58-6:13 or so, the 50 cal flies through the acrylic, leaves its stress cone, flies on, and then the acrylic shatters into pieces. If you watch closely, the bullet itself leaves a hole with cracks protruding out of it, but after the bullet is already clear through and long gone (in terms of the slo-mo video), then the acrylic breaks apart further into the big chunks that fall to the ground. Why? I initially thought it could have been that the cracks had momentum, but seeing as how they stop and then start again, that doesn't make sense at all. Then I thought maybe it would be the wind. I don't know for sure, but I don't see how a 50 caliber bullet wouldn't go super sonic, so maybe due to the nature of super sonic rounds the acrylic breaks the rest of the way from the force of the air wave catching up to the bullet and the cracks that the bullet left in the acrylic weakened it enough that that wind was enough to break it the rest of the way. It makes sense to me, but idk if the numbers would actually check out. I'll be honest, i don't even know if 50 caliber rounds are super sonic at all. This is 100% hypothesis, so I could be completely wrong in every way, but if anyone knows the answer please let me know, I'm curious.


    Eventually in the way way far future I hope the F-22 is going to be the jet used by the Thunderbirds for Air shows. The maneuvers that those can do will be insane.

    Anyone else get a major Mythbusters vibe with that guitar riff at the beginning? Destin embodies the same childish excitement I had watching that show 16+ years ago. Gotta love it!

    Does anybody remember the tv series American shooters. If so, this was the man behind the bow. He was the best then, and still is today.

    🤣 I fell asleep while I was getting mine, never thought I’d see this on this channel 😂


    Airforce is recruiting big time! So teens who like planes should enlist to gain skills, don't worry if you're not a genius, just ask for help. You get your aerospace engineering degree, among other things.

    Mach is actually a function of temperature, not altitude. The calibrated airspeed is lower due to the lower density of the air, but at the lower temperature Mach 1 is also a little lower in terms of true airspeed (TAS) , but nowhere near the degree you saw in the CAS. Given the same temperature at two altitudes, Mach 1 would be at the same TAS

    One of the saddest things is coming to the realization that because of something physical or mental, you'll never be able to fulfill a lifelong dream. For example, i wanted to be an astronaut but I accept the fact that I am too dumb to leave the planet.

    I think what's most amazing about the Saturn V, is we did ALL of this with out the internet. Today, kids can't even get out of bed without checking their social media apps.

  56. Derek Rodriguez

    If you think about it, why don't the software engineers make an algorithm to check the subtitles. There are auto-generated subtitles on every video. Considering that all of the news video literally had exactly the same script, you could theoretically make a program that compares video script to video script. That would stop many videos with exactly the same content being posted. By doing this, the attacker would make less money, if motivated by revenue.

  57. Ryan Laird

    I love this video second time watching. Linus and you should have a channel

    I recognized that light green engineering paper, I went through dozens of pads of the stuff 30 years ago in engineering school. Flashbacks! But unlike Destin I never kept my notes from those days. Well, except for my Dynamics of Structures class in grad school which I kept as a trophy because it was so hard!

    1. Guy Rutledge

      @Soinas Doyi In the field of psychology, the Dunning-Kruger effect is a cognitive bias in which people with low ability at a task overestimate their ability. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence.[1] As described by social psychologists David Dunning and Justin Kruger, the bias results from an internal illusion in people of low ability and from an external misperception in people of high ability; that is, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others." _ do you still love it? :) Cheers

  92. AesopsRetreat

    I've always considered that they are picking group leaders. Each bird will follow a certain leader, and they do this sky dance selecting who those leaders will be. Then when leaders are chosen they all fly off in different directions and the offspring come back the next year to do it all over again.
