    There are now more of the world’s smallest nerf guns in existence than there will ever be just regular nerf guns.
  • @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 ❤
  • @Kathlanus
    What I love most about this video is 19:25. Give people like these a fun yet seemingley rediciulous project and you never know what kind of idea it sparks in their head.
  • @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
  • @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
  • @th3milkman561
    I love how mark’s just like “this is so small, light cant even reflect off of it”. Just so casually as well.
  • @AVASdesertRACER
    i LOVED the detail of HOW a nerf gun works in the beginning. Mark Rober is the best YouTuber out there, making science fun for kids, adults, dads, moms, everyone.
  • This was nothing short of inspiring! And born from such a simple first idea! A true reminder of what creativity and brilliance the human spirit is capable of, and that - although some might stand out - it's usually not a single person's achievement, but a string of steps taken by a whole bunch of people that lead to mankinds' most amazing feats. Absolutely beautiful.
  • @CincyKid1990
    Mark Rober is a storytelling genius. His ability to trick my kids into loving science, math and engineering is nothing short of a miracle.
  • @MawaMaverick
    This guy pulls off something that is clearly extremely difficult to achieve and compresses it in a 20 minute video coupled with happy music. Well done.
  • @user-sc3wt9pj2i
    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!. 1:40I absolutely love the edit/cinematography here. It's so seamless!.
  • @Annnabannanna
    Mark is actually incredible. Never thought I'd get so hooked into physics.
  • @MemeGod201
    Mark is the guy that will literally remake all of his childhood toys into something insane.
  • @TimeBucks
    Love more detail on how the DNA was self building.
  • 18:10 as someone who only took one year of Biotechnology in High School, THAT'S LITERALLY THE FIRST THING THEY TEACH YOU!
  • @Alexis84DE
    I just want to say hats off and thank you to all the amazing students, researchers and professors ❤ what an inspiration for the future
  • @poluefemus
    you know you’re screwed when you’re fighting against a guy with not only the biggest nerf gun, but also the smallest nerf gun
  • @fishdripfn
    Mark is the definition of quality over quantity
  • @Decepticant
    In-freaking-sane! I can't express how important what you're doing is for the scientific community and the advancement of humanity. It's truly amazing.
