I can break the sound barrier with a bath towel.
Impressive but I can open Walmart doors without my hands
i cant break the sound barrier with a handkerchief
Same bro
That is soo Alabama
Hahaha r8!
Asians: It's just a belt, it can't hurt anybody.
The belt:
The blank : break the sound barrier
So when people get whipped they’re essentially getting hit at the speed of sound with a piece of rope.
but can they produce light with the sound?
@Trip Gil I am sure that those who are beaten will see light.
@Andoni Olea 🙏😈 [excellent]
@Trip Gil Always think of the cruellest scenario. 👿👿👿
@Andoni Olea 😄☝........the world is ending, and no one will be saved, since even though they were given salvation they rejected it, and once the doors closed, none will be permitted in, no matter how much they cry or beg😓
9:39 dabbed so hard he teleported.
Bold move. Thinking we wouldnt notice you trying to make us watch that ad for audible... Nice try.
This is the sound when your Mexican dad takes out the belt
JASON'S WORLD maybe it’s a catholic thing lol
Bruh, my white dad always gave me the jeweled belts
Why Mexican
maybe cause his dad is mexican..
My bath towel is greater
I've been subscribed for almost 4 years I believe and this has to be the most interesting video you've made in my opinion. Keep up the good work!
@Martin Kuliza Right, lol?! She's the goods 😍😁💯👌
@Tiffany Hackerspace, LVL1 Sec'y
hehe.. too right
@April Jennifer Choi Is the paper already published? I couldn't find any publication yet :/
@ParanoidMaster To the best of my knowledge, it has not. I'm not sure where it stands at the moment.
@SmarterEveryDay you live in Alabama
Dude, i live in Mississippi
4:10 “there’s a dude in it that looks like a moose wearing bells and a clown suit” EXCUSE U HE’S CLEARLY A REINDEER 😤🎄
Ahh, finally, a man of culture.
Ah yes, The Whip-Cracking Reindeer Man...
Bruh
I'm dying
This was actually a lot more interesting than I thought it would be.

Hang on I just realized something.... the whip in slo mo looks exactly like the dancing inflatable guys outside of car dealerships.. SOOO if the inflatable moved fast enough... oh god SUPERSONIC INFLATABLE MEN
9:30 Grimes' son
Destin, this is some serious hardcore science! AWESOME!
hardcore... i see what you did there
Hardcore? ( ͡° ͜ʖ ͡° )
This sentence should have ended at the word "hardcore".
Yeah, pretty hardcore po... uh, science
:P
Interesting, now how can we apply this to space travel.
Attach a spaceship to the end of a huge whip and get to space without rocket fuel
@Jackson Spasojevich the only problem is that the spaceship could only weigh a couple of kilograms and you'd already need a massive qhip
0:33 really thought he was gonna say “sadism”
I love at 4:54 how Destin says “Learning stuff”
Stay humble Destin 😂
3:40 Oh wow, you can actually see the shock wave initiate. You're literally seeing it as it goes from subsonic, to transonic to supersonic, right? That's incredible
best example that everyone can relate: when you slurp on noodles and when the end of one is right before your face, it smacks you
Asian
1000th like bich
OMG that is so true
Don't slurp. You won't smack yourself in the face, won't make that disgusting sound, and won't make a mess on your face and clothes. Problems solved.
@Mikeztarp There never was a problem that needed to be solved, I only slurped when I was 6 because it was fun and I never asked for a solution.
4:55 "Destin - Learning stuff" lmao
Dr. Hazeli: Mechanics
Dr. Kanistras: Aerodynamics
Dr. Kang: Aerodynamics/ATOM Lab
Parents: Belt Master
"Is that awesome?"
"Yes, sure"
If you want to reach British levels of understatement, I think a PhD is the fastest way.
I was putting my pants belt on one time with a pulling motion and got a painful lesson in whip dynamics. One of those male life lessons.
I clicked so fast my finger broke the sound barrier.
I clicked so fast that my finger travelled in time
@RedemptionSoS I see what you did there
@sandwich- kun where is it then?
@Nice the question is when is it
If you say The Light barrier got more likes! :/
i knew there was something weird about that "lady"
They all love science. Except for biology, for some strange reason.
When you take small questions way to far lol images being like I wonder why pb and j tasted so good make a video about that
It's been eight months, Destin! Where's your paper?!
This is wonderful! it sounds like
April and Destin: "Hey Doc, we have a cool idea, been researching about whip dynamics and want to combine an experiment to have a function of multiple properties..."
Doc: "Sure, sounds great, let's build it" *brings other Doctors to the party*
I want to be able to do that
Thank you Destin, this is great
I just watched a video starring a pretty lady with a whip.
It was about science.
0isay it’s just cuz she looks like a man and sounds like one too. There’s nothing wrong with it tho.
So glad yet so disappointed im suspicious of people's actual gender. It was pretty mu ch a dead give away in this case and its kind of hard to watch him call him "her". The whip was still badass tho so i had to stay for that.
all i need is to read this thread to lose faith in humanity
you think thats a lady ? listen to his voice
@savagex466 Thanks for being the 80th person to tell me how I failed :D
The fact that it doesn’t crack at the end like we all thought disturbs me and almost make s me sad idk why
Guy with a whip: *exists*
Destin: "I'm about to end this man's whole career"
4:09
me: breaks sound barrier
Light: hold my atoms
Destin : "Learning Stuff" , that was too funny
OMG! 40 years ago a girlfriend convinced me to join her in an evening class where we made our own braided leather bullwhips from scratch. We started with tanned hides, sliced them, shaved them, dressed the strips to precise tapers, oiled then braided them. It took a team of two about 20 hours to make both whips. Then we got to learn various techniques, from gently capturing things (we learned to wrap our whip around a balloon without popping it), to wrapping hard enough to break things (my favorite was sidewalk chalk, which exploded).
But the best part was learning to crack our whips. We started by simply rolling the loop of the whip down onto the floor, where it would snap when the tip smacked down. Then we gradually added more energy, a truly small amount at a time, until it started to crack in the air. Large, graceful motions that finished with a crack. Then we learned quicker moves that brought the snap a little closer in, where we learned to place it where we wanted it. I envied the folks who were ambidextrous with their whips, because my right arm was getting ready to fall off.
We wanted to see if we could capture the motion of the whip by cracking it horizontally over sand, so a few of us took our whips to the beach and tried to crack the whip horizontally within an inch of the sand. Almost impossible to do, but once in a while we did notice a puff of sand happening well before the whip had reached full extension, from a part of the whip not in contact with the sand. If only...
Fast forward 25 years, and I was on the team making a camera that could take 100,000 frames per second (the Redlake HG-100K). When the third alpha unit became the first to work at full speed, we searched for targets that would both test the camera and thrill Marketing. Popping a balloon wasn't nearly fast enough. I thought back to my days with the bullwhip, and we immediately went out and bought a few. Despite dumping a zillion lumens into the field of view, nothing useful came of it. (Clearly, using Schlieren photography and capturing the shockwave is crucial.)
What we did wind up doing was pointing the camera at the HID bulb in an Epson video projector (torn from the ceiling of a conference room), where we captured the most amazing video of the arc wandering between the electrodes within the bulb envelope. We put a GIF of the sequence up on our website (this was before YouTube), which caused some small level of buzz online. The next morning we received phone calls from the Japanese executives of both Epson and Panasonic (the maker of the bulb). It turns out that arc wander was the primary factor limiting projector sharpness, so stabilizing the position of the arc was crucial to gaining any benefit from using higher-resolution LCDs. Two days later they were in our offices for a demo, and left an awesome pile of money behind when they departed with our very first beta unit. Their problem was that high-speed film limited the rate of innovation to one test run per day, with the film developed overnight: Our camera allowed them to do a dozen runs every day, leaping their R&D further ahead of the competition.
You may have noticed I mentioned we had to go out and buy some bullwhips. My treasured handmade bullwhip had disintegrated within a year of making it: Evidently, the tanning process used on the leather wasn't compatible with the oil we applied to it. It sure was fun while it lasted.
Now you two have got me wanting to make another one!
I just want to say I love your comment. Thank you for taking the time to write it.
Worth the read 9 months later

"A boomer says omg and types a text wall!"
Nice but long story didnt get half way through, video is better and yu prob think that too
In would not want April to be my mother. Oh god imagine accidentally breaking her favourite vase
"Hey hun how was your day?"
"Oh good just spent all day with a woman who's really good with whips."
"...."
You think that was a womon ? o dear ...
@savagex466 OMG what a shock, i didn't notice!
upon closer inspection "she" has some masculine traits.
@Caveman . I could be wrong .. and If I am then Shame on me I guss. Times are strange these days ...
@savagex466 you're not wrong.
I wonder how the first whip was thought up. Like, you're just a hunter-gatherer, doing your thing, and you find a bendy stick and think "I'm going to hit someone with this"
When I was a kid I used an 18' leather tipped whip. I was good enough to pop horseflies w/o touching or make a mule turn his head to me instead of his back hooves
"Let's make a YouTube video!"
"Let's publish research!!!!"
Why not both?
Who has the desire to listen to Russian rap. Go to my channel, I shot a clip. I will be glad to see you
@AIDYS it would be much better if you didn't whisper and used your voice more precisely, good job anyways, keep it up :)
This is why I love this channel. YouTube videos that are worthy of being published studies.
thunderf00t had also quite surprising paper grow out of a youtube project - he had also include aknowledgement of help of his patreon supporters into it.
wait a second, isnt that how loud my scream is when my dad hits me with the belt?
Fat CJ: "I need the whip, fool."
4:57 this is litterally like in school, "learning stuff"
Imagine getting hit my a piece of cloth at the speed of sound
We were able to observe the drag in slow-mo thanks to this super strong lady. Therefore we will call her the drag queen
god, the amount of work that's put into this is amazing.
Me: sees the title
Me again: tHaT wOuLd HuRt
The coolest thing about a plane flying above Mach 1 is that it's engine was already running above Mach 1 before the plane
Isn't the engine contained by the plane? How can it have different velocity?
@Mizushima Fujin cuz it spin
@Dark Lightning Müller's Correct!
Wow thats a stupid comment
