Ambiance and musicy things by: Gordon McGladdery did the outro music the video.
The thought is it my efforts making videos will help educate the world as a whole, and one day generate enough revenue to pay for my kids college education. Until then if you appreciate what you’ve learned in this video and the effort that went in to it, please SHARE THE VIDEO!

    Really liking those integrated watermarks

  2. CaCawQrow says:

    Good idea on Water marking your high speed footage!

  3. Shamial Rashid says:

    you can tell this guy’s been fucked over by other people re uploading his videos

  4. Dream Big says:

    Fake, the propeller is a paid actor.

  5. Veritasium says:

    Great work Destin! If this video doesn’t blow up YouTube is seriously busted.

  6. dligac says:

    It’s really smart to put watermarks on the most amazing parts of the video so it doesn’t get stolen
    I don’t think I’ve seen that yet but it’s a great idea

  7. Andy Jones says:

    Can we just take a moment to congratulate whoever edited the writing onto the propeller blades? That must have taken such a long time to do considering it was most likely done on a frame by frame basis. They even got the sun glare spot on. Bravo. 👏👏👏

  8. Luke Stringer says:

    Still not as bad as the 7 News logo 😀

  9. Vincent Wood says:

    How do the guitar string patterns compare to their recorded sound frequency on an oscilloscope?

  10. Mike Alvarez says:

    Change this channel from “Smarter Everyday” to “Smarter Every Month”

  11. Nasal Spray says:

    5:09 the word video is auto tuned

  12. 865MusicByHavoc says:

    Destin, could you explain why you can actually view “The wagon wheel” or “pinwheel” (The phenomenon that makes a spinning object look like it’s slowing down and then it seems to change direction) happening with your bare eyes? Thanks!

  14. Rosson91 says:

    Great way to stay ahead of the freebooters with the watermarking!

  15. Ali Ahmed says:

    I took a photo once for a spinning coin and that happened, i won number 1 in college photos gallery ☺️

  16. Daniel Gonzalez says:

    Please don’t bring the quality of your content down with those clickbaity thumbnails with arrows and circles..so ridiculous

  17. LeFinMinion says:

    Something weird in the thumbnail.
    Red circle in thumbnail.
    Red arrow in thumbnail.
    Title phrased as a question.

    Clickbait ingredients, but quality content. Nice.

  18. Pearl127 says:

    You outdo yourself.

  19. Carlos Olivo says:

    I really appreciate your videos, and all the different subjects that you cover. I am a 9th grade drop out, and the traditional way of our school system just wasn’t for me. However despite my lack of documented education, I’ve found success in hands on experience. I really would just like to thank you because I really do enjoy getting smarter every day.
