Creating the World’s smallest Nerf gun 5 times in a row. Reserve your CrunchLabs Build Box for the holidays here- crunchlabs.com

I started a company called CrunchLabs, where we build a toy together, and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have a really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com

Thanks to these folks for providing some of the music in the video:

    There are now more of the world’s smallest nerf guns in existence than there will ever be just regular nerf guns.
  • @WillyOrca
    Every single time they made it smaller I was like "well this is it they can't possibly get any smaller than that." and by the end I was just totally in awe.
  • @EileenTheCr0w
    Mark slowly becoming the Willy Wonka of engineering. Just incredible and inspiring on so many levels.
  • @user-xj8el1ul7b
    初めてこの人のチャンネルを見たんだけどものすごい数の言語の翻訳(しかも音声)があってびっくりした!!しかもわかりやすい
  • @CIubDuck
    Having actual students working on this problem is so cool. You could've gone to the top scientists or physicists with this problem, but no, you went to the school and got the students to use their head and work out a solution for this. I really respect that.
  • @annakalkman552
    I would LOVE if Mark created a second channel aimed at engineers themselves- I appreciate the explanations that everyone can understand, but so many of these videos bring me so many questions that are more in-depth that I would love to hear him explain more

    I absolutely love the edit/cinematography here. It's so seamless!
  • @katiebutler6624
    I love how Mark always makes sure to go back and include his favorite mentors and teachers into his videos ❤
  • @fotunatworld
    こういうワクワクする実験が未来のエンジニアを生み出すんですよね!
    是非未来の為に活動を続けて下さい!
  • @JacobL228
    This guy is awesome. I'm so jealous of his intelligence. It's also always a pleasure to listen to the world's foremost expert in something explaining his field of expertise with such enthusiasm. However, I will say that at some point, Mark forgot what qualifies as a NERF gun; it has to be able to fire a dart.
  • 8:15 “it was the smell more than anything that really brought back the nostalgia” This has a reason. That reason is, the processing center for smells in the brain lives extremely close to the memory center of the brain. This makes it so that the electrical signals to trigger remembering can take a shortcut from the smell processing center to the memory center.
  • @Melone10001
    Im a physicist in Nanofabrication. This is impressive on another level. You made a video that children can watch that has more science inside than most lecture courses at university
  • @divergente00
    Qué locura, sin duda este canal de Youtube es de los mejores que he encontrado, es absolutamente sorprende.
  • @BQwain
    I wish their were a LOVE button rather than simply a like. Mr. Rober, your abilities to inspire, guide, educate, and enlighten on every level is superb and something which I am so very proud and glad to be able to experience. Kudos to you Sir, and Thank You ever so much.
  • @BalgaBear
    2:10 this comment hit me so hard, as so many people who are defined as "lazy" sometimes, can be the smartest and hardest working people.
    Energetic rarely got me anywhere, it was always about who I knew and not what I knew.
  • @richardviana3302
    Deu até vontade de me formar em outra engenharia depois desse vídeo, muito bom!!
  • @user-ie8ls3rk9f
    ふおー、まじいい動画じゃん。
    最初から最後までナーフガンたっぷりで勉強になるし、
    好きを極めるとこうなるのかーと羨ましくなった。
  • @gason1000
    it's amazing how Mark uses the nerf gun to hook u into watching and then secretly makes u learn all about scientists who actually deserve the exposure ❤
  • Fact that my engineering teacher 3-D printed one of these shows how impacted these are. He even gave us a few lessons on this.
