hello from 2017! I agree with squid master, I would go so far as to say these guys need a high quality whip. that whip looks pretty cheesy. check out nicks whip shop or caliber whips.
Exactly.... It's not moving that many feet cause no one snaps it back on themselves as they did. Wave should extend away from user down the line and you would see the required movement. Dumb ass! Probably went to some community college
pit bull no but the crack it still there which is what they're trying to measure, seeing if it is a sonic boom, anything fatter will make no difference what so ever
Which would be correct, yes the crack is there, but they aren't measuring vertical path either. They only measured the horizontal path of something that moved in all 3 dimensions.
i demand a retest with better equipment and someone who actually knows how to use a whip rather than flail it around like an idiot, i suggest you contact adam winrich, he is quite skilledunlike you.
I agree! Though I think it is possible that even though whip cracks are loud, they don't actually reach the speed of sound. I mean, we can smack our hands together really hard and create a loud crack like sound, but that is in no way anywhere close to the speed of sound!
Nate Dawg There's a discovery channel show that slowed down and recorded mini sonic booms forming as the whip cracks. Just search TH-cam for "bullwhip time warp". If breaking the sound barrier requires going faster than the speed of sound and characterized by a sonic boom, then by correlation, the whip doesn't just reach the speed of sound, but goes even faster.
Legit Druid It only takes a bit of practice to crack better than these guys. It looks like they literally just bought a whip the day of the test and picked it up for the first time on camera.
They're looking at it wrong anyway. The end doesn't move faster than the speed of sound for any extended period of time, nor really in the same direction as the whip. It's the coil at the end violently unfurling that breaks the sound barrier, which means it's more of a small circular movement than one that will show up on a straight ruler like that. A better way of doing it - and one that wouldn't require a more high-speed camera - would be to calculate the kinetic energy of the standing wave at the start or midpoint of the whip, then calculate the resulting velocity after it had propagated down the length of the whip, losing mass while retaining energy and thus gaining said velocity. If the calculated velocity exceeds the sound barrier by any substantial amount, it could be assumed that the actual velocity had broken the sound barrier despite any energy loss. At least, that's how I'd go about it. :)
With the help of a modern high speed camera and TH-cam, Will and Norm clearly demonstrate to the world yet another in a never ending series of perfect examples of the Dunning-Kruger Effect; namely, how completely unaware the unskilled are of their own ineptitude. ... One can easily assume that Dunning and Kruger are quite thankful for TH-cam providing such a large body of evidence supporting their study by providing both the ability to upload videos and allowing comments.
Anon Ops It should be obvious, but... The fact that they publicly posted a video demonstrating how little they know about using a whip; in a way that could cause serious injury; in an attempt to "prove" something that has been shown, reliably, in many other places and being serious about it; while failing to be scientific about it -- and, at their chronological age, not being embarrassed about it enough to remove the video. ... D-K: Unskilled individuals mistakenly assessing their ability to be much higher than is accurate. ... "If you're incompetent, you can’t know you’re incompetent.… The skills you need to produce a right answer are exactly the skills you need to recognize what a right answer is."
Not only did they demonstrate their incompetence in using a whip, they also demonstrate incompetence in purchasing one. Those whips are cheap, mass produced pieces of crap. If you have the budget for a high speed camera, you can drop $200-300 on a high-end product. Instead you bought a Chinese stage prop. Good job.
+Max Zou are you offended? cause it is funny. some selfsarcasm does not hurt. All of us who laughed at this comment do not consider ourselves racist. you seem like a reasonable guy.
If out of shape amateurs with improper technique can get to over half the speed of sound, it's most definitely possibly by somebody faster and more skilled.
It does break the sound barrier. They did not crack it correctly nor did they have the equipment required to accurately calculate the speed of the whip.
Wow that was lackluster for you guys. If you were to make this video again today, I know it would have been much more exact. I think this deserves being revisited and being done properly.
I really like this channel, but this video fell way flat for me. For anyone who hasn't used a whip before, you can get less substantial cracks without breaking the sound barrier. This is what they got. Its almost impossible to get a real crack with the technique they used. With proper technique, the popper will break the sound barrier, and you will get a real crack which sounds like, and is about as loud as, a small caliber gunshot (like a 22).
Also the ruler is measuring movement in a single axis. The whip does not conform to that plane of movement. It would be better to try to estimate speed by using a grid of squares behind the whip crack.
I thought the British were well known for being self-deprecating. TH-camrs sure like to show how just plain stupid they are...and obviously proud of it sigh...
As much as it is fun to see Will and Norm struggling to use the whip, I think it would have been a lot more accurate if you guys got the actual bullwhip expert
You can shoot as short a shutter speed as you like, so even shooting 30fps, you can capture 1/2000 of a second. Shooting 480fps, the standard shutter speed would be half that (since when shooting film, the shutter is closed for half the film to allow the next frame to seat into registration), or 1/960th (rounded up to 1/1000) of exposure per frame (though with digital cameras you could shoot 1/480th of a second at 480fps. To capture 1/2000 of a second, you simply cut your exposure time in half.
Do NOT ever crack whips like this. that popper is flying straight towards his face. this is a text book way to remove eyes. This entire video made me uncomfortable and angry be cause very clearly these guys cant take 10 seconds to search youtube for "bullwhip techniques" or "bullwhip cracking" or even "how to crack a bullwhip" INCREDIBLY uncomfortable to watch
I wish that you guys had a better slomo camera like the Phantom Flex. I understand they are INCREDIBLY expensive but they shoot like 10,000fps+ and in HD. Love the video!
They don't know how to properly crack a whip... yesterday to prove them wrong I cracked my whip at 240 fps on a cell phone camera and was able to get supersonic vapor condensation over most parts of the whip especially the tip
Yeah most people think you can crack a whip the way they're doing it. I'd like to see them bring in someone who knows what they're doing and do a cattleman's crack. I bet you they would have completely different results. At least 400 FPS more.
It's great that despite not being able to show the breaking of the sound barrier, you still put up this video. Science is science, whether you get the results you wanted, or not.
I think your looking at too much of the whip. only the extreem tip actually moves fast enough.There is another video that shows the distortion of air that occurs at the moment of the crack
1. It's clear they didn't even google "how to crack a whip." 2. They were measuring the part of the whip's motion that went in front of the ruler. If you watch just a second after it passes the ruler, the actual crack happens in the upper left quadrant of the screen. They didn't even seem to notice that it moves too fast there even for the high-speed footage.
Anastasia P. Maybe before being aggressive for no reason you should research that Adam Winrich is a whip expert and one of the two MythBusters stars is Adam Savage. Your comment is entirely irrelevant to what the OP wrote.
You can liken fps to photos, so 480fps is 480 still images in a single second, so if you play it back at 24 or 48 the fairly generic fps playbacks it plays through all 480 frames in however long a period of time that would take.
For any would be whip enthusiast, this is a perfect example of how not to crack a whip and bring it extremely close to hitting you directly in the face. This is by far one of the most dangerous ways to actually crack a whip, so please for anyone that wants to get one or already has one, please do yourselves a favor and check out videos of how to properly crack a whip. It is actually much easier and safer than it is done here.
To be honest I would not use that type of crack (i don't think there is even a name for that). I would use the cattleman's crack , the overhead crack or a type of flick. They should have gotten someone else to do the whip cracking.
In order to work out how long one frame is when shooting at 480 frames per second, you need to divide 1 second by 480, as there are 480 frames in that second. This equals 2 thousandths of a second
If you let it roll out horizontally the way it's supposed to, you'll find that the end DOES travel the 1.6'/s it needs to in order to break the sound barrier. What you are doing is snapping the whip back on itself-and vertically at that-which is why a) you keep hitting yourselves, b) you broke the fall on the whip (snapping back puts way too much strain on the whip: let the whip do the work, not your arm!!!), and c) why you are not getting a minimum 1.6' horizontal movement within 1 second.
The reason they were unable to see it break the sound barrier is because their camera wasn't high speed enough and way to zoomed out. It's only the very tip, the last couple of mm of the whip, that breaks the sound barrier. And it only does so for a incredibly short amount of time when the "wave" of the whip reaches the end. Have a look at this video, at 2:10 you can the tip of the whip creating the shock waves /watch?v=lbomsOPSSII
all these ppl in the comments talkin bout how they are "disappointed" that you "didn't know" how to crack the whip. meanwhile im just enjoying watching yall fuck it up just as much as I would
wait i am pretty sure that the points you guys measured the velocity of the whip was not the actual time it cracks. from what i saw, its when the tail end of the whip circles the closing loop at the end of the whipping cycle...correct me if i missed something lol
You are correct, they are doing it just about as wrong as is possible. They are using the whip as if it was a hammer, just swinging it up and down and hoping for the best. This not only gives them a weak and ugly crack but is also quite dangerous as the whip is traveling towards them when it's cracking. And this the way people hit them self in the face.
If you want a solid answer go check out “smarter every day” they give complete explanation and use a phantom high speed cam to visualize the exact moment it causes a sonic boom.. pretty insane!
They're testing if the reason a whip makes the cracking sound is that it breaks the speed of sound. If Norm can make it crack, yet it does not break the speed of sound, then logic dictates it is not breaking the sound barrier that directly causes the cracking sound, so even if a professional whip guy could cause it to break the sound barrier, it would still not be necessary to create the cracking sound.
As someone who cracks whips as a hobby but had to learn how to crack them *properly* what he’s doing at 2:03 , NEVER DO THAT. you can seriously injure yourself by holding the end of a whip while attempting to crack it. This *screams* “we don’t know what we’re doing.” If anyone takes away anything from this video, whips do break the speed of sound, can and WILL hurt you if you’re using it wrong, and are incredibly dangerous if used incorrectly, which is how it’s being used in this video. This is a showcase of exactly what NOT to do with a bullwhip.
wait but then what was that thing at just before 1:18 when they are showing the slow motion of the whip? I felt like I saw a little whitish/cloudy thing just at the end of the whip - which is typical what the area around something that breaks the sound barrier would look like. I saw the whole video several times but it happened only once however it looked very much like the shock wave you'd get from breaking the sound Barrier AND it coincided with loud "crack" of the whip (which also happened only once). It's very faint but if you watch closely you'll see it.
I was making a joke based on their numbers. But the speed changes, as does the direction. That's exactly how whips work. As the wave gets shorter the speed of the wave gets faster, until the moment it changes directions. At that moment the wave length is at its shortest and fastest. It reaches the apex and changes directions on itself. The remaining energy that is left in the whip is used up as the whip cracker accelerates making the directional change and as Guile always says, "sonic boom."
The answer is there but your initial bias prevents you from "seeing" it.The crack occurs NOT at the fastest speed of the whip tip but rather right after the tip stops and begins to accelerate. It has to do with a breakdown of the air boundary layer around the whip tip. Does that mean that all the physics "experts" have it wrong? Yep...along with a LOT of other really basic stuff. This is just one example.
The main two problems are not the camera, but the way you cracked the whip, and the area you were calculating. The whip was actually cracking off camera in the slow motion. Performing the Forward Crack (also known as the Cattleman's Crack) or the Flick would have been much easier to identify.
Glad I wasn't the only one who thought that. I literally yelled "Nooo!" at that shot. I wouldn't do that with my nylon whip and it's a lot more easily cleaned than leather.
It is the very tip of the whip that breaks the sound barrier, for a very short period of time. What you would need to to is get a much smaller ruler, and a very accurate shot to see the actual sound breaking.
No it's well known that the reasons that a whip causes that with things around or even towel does is because the tip of it is breaking the sound barrier and the rushing there to fill in the vacuum left behind is what creates the crashing soon.
Geoffrey Zoref Incorrect, the crack is caused by the loop in the whip moving down the length of the whip faster than the speed of sound: www.scientificamerican.com/article/true-cause-of-whips-crack/
Respectfully: look up "on the dynamos of a bull whip" also, the link that you cited also says that it does break the sound barrier, but that it isn't the entire reason for the crack only part of the reason for the crack only part of the reason for the crack.
Well, as long as there's the "cracking" noise affected, it really doesn't matter. If the crack was really caused by the speed barrier broken and the crack occurred for them, then they should've broken the sound barrier when they did it.
altitude has nothing to do with the speed of sound. when air is the medium the temperature of the air directly effects the speed. (hotter = faster, cooler = slower) It is not audible but it is measurable.
Did you guys take into consideration the parabolic nature of the whips movement? The ruler should be used as more a reference point than an actual ruler, since the whip didn't follow a straight path.
they should have got one of those magnetic things that tell you the speed of bullets and then put a little bit of foil or wire on the end of the whip, and then got a decent whipper, from texas
Congrats you are now world champion of the world, even jesus is coming down to pat your back, with his statement, "Well job - dramatic pause -, my son"
Okay, can I suggest that the reason you didn't catch it is because you weren't throwing the whip correctly to get an optimum crack. You were doing a very simple crack, but it wasn't getting the actual sound barrier. Standing and throwing the whip forward and filming the coil going down the length of the fall would have let you film the actual crack at the end, in a very predictable place. Also frontal shots, and back shots would have shown more as well.
At about 1:18-1-19 you can see the whip quickly break the sound barrier..I noticed the small bit of moisture particles at the end as you would see on a jet breaking the sound barrier..or at least on the edge of breaking it. But either way, pretty cool stuff :)
They were measuring at the wrong time. The whip "cracks" when the fat in in circular motion aka when it is "in" the loop, that is when it is moving fastest.
We used the ruler as a reference to determine scale in the final framegrabs.

youre trying to measure a circular motion with a linear measuring device
Who needs arc segments anyway? Though, they do look like they know a-thing-or-two about pi(e).
But if it's going past the speed of sound linearly, it'll be going far past the speed of sound circularly. So it kind of could work...
It's not a very uniform circular motion so even if you did try to measure it circularly it still wouldn't be accurate
If they're trying to measure the velocity of the tip and just the tip, does it really matter?
I really like this channel, but this video fell way flat for me.

It's only the very tip, the last couple of mm of the whip, that breaks the sound barrier. And it only does so for a incredibly short amount of time when the "wave" of the whip reaches the end.
Have a look at this video, at 2:10 you can the tip of the whip creating the shock waves /watch?v=lbomsOPSSII
At 3:20 I jumped at the bee that flew by and I’m dead rn😂😂
Where's Adam right now? This is perfect for him!
Dude they just are doing the EXACT SAME THING as the Mythbusters did in the Indiana Jones Special, THEY'VE ALREADY PROVEN IT!!!
OMG the places where you guys started to measure the distance was before the whip cracked. If you guys knew about whips you might have known that
all these ppl in the comments talkin bout how they are "disappointed" that you "didn't know" how to crack the whip.
meanwhile im just enjoying watching yall fuck it up just as much as I would
I may sound foolish but did it seem like they were measuring distance on a straight line when the whips path was anything but a straight line?
omg u can actually see it going mach 1+. You see the air bending around it witch makes a small sonic boom, awesome
wait i am pretty sure that the points you guys measured the velocity of the whip was not the actual time it cracks. from what i saw, its when the tail end of the whip circles the closing loop at the end of the whipping cycle...correct me if i missed something lol
You are correct, they are doing it just about as wrong as is possible. They are using the whip as if it was a hammer, just swinging it up and down and hoping for the best. This not only gives them a weak and ugly crack but is also quite dangerous as the whip is traveling towards them when it's cracking. And this the way people hit them self in the face.
he learns to crack the bullwhip like learning to drive in reverse for the first time
If you want a solid answer go check out “smarter every day” they give complete explanation and use a phantom high speed cam to visualize the exact moment it causes a sonic boom.. pretty insane!
They're testing if the reason a whip makes the cracking sound is that it breaks the speed of sound. If Norm can make it crack, yet it does not break the speed of sound, then logic dictates it is not breaking the sound barrier that directly causes the cracking sound, so even if a professional whip guy could cause it to break the sound barrier, it would still not be necessary to create the cracking sound.
As someone who cracks whips as a hobby but had to learn how to crack them *properly* what he’s doing at 2:03 , NEVER DO THAT.
you can seriously injure yourself by holding the end of a whip while attempting to crack it.
This *screams* “we don’t know what we’re doing.” If anyone takes away anything from this video, whips do break the speed of sound, can and WILL hurt you if you’re using it wrong, and are incredibly dangerous if used incorrectly, which is how it’s being used in this video.
This is a showcase of exactly what NOT to do with a bullwhip.
Finally, high-speed footage of a guy whipping... himself.
wait but then what was that thing at just before 1:18 when they are showing the slow motion of the whip? I felt like I saw a little whitish/cloudy thing just at the end of the whip - which is typical what the area around something that breaks the sound barrier would look like. I saw the whole video several times but it happened only once however it looked very much like the shock wave you'd get from breaking the sound Barrier AND it coincided with loud "crack" of the whip (which also happened only once). It's very faint but if you watch closely you'll see it.
I was making a joke based on their numbers. But the speed changes, as does the direction. That's exactly how whips work. As the wave gets shorter the speed of the wave gets faster, until the moment it changes directions. At that moment the wave length is at its shortest and fastest. It reaches the apex and changes directions on itself. The remaining energy that is left in the whip is used up as the whip cracker accelerates making the directional change and as Guile always says, "sonic boom."
this was cool like a mini mythbusters episode, and norm actually looks like he has a pulse.
What did the neighbors think, after hearing whipping and "ow" sounds
The answer is there but your initial bias prevents you from "seeing" it.The crack occurs NOT at the fastest speed of the whip tip but rather right after the tip stops and begins to accelerate. It has to do with a breakdown of the air boundary layer around the whip tip. Does that mean that all the physics "experts" have it wrong? Yep...along with a LOT of other really basic stuff. This is just one example.
The main two problems are not the camera, but the way you cracked the whip, and the area you were calculating. The whip was actually cracking off camera in the slow motion. Performing the Forward Crack (also known as the Cattleman's Crack) or the Flick would have been much easier to identify.
Glad I wasn't the only one who thought that. I literally yelled "Nooo!" at that shot. I wouldn't do that with my nylon whip and it's a lot more easily cleaned than leather.
It is the very tip of the whip that breaks the sound barrier, for a very short period of time. What you would need to to is get a much smaller ruler, and a very accurate shot to see the actual sound breaking.
No it's well known that the reasons that a whip causes that with things around or even towel does is because the tip of it is breaking the sound barrier and the rushing there to fill in the vacuum left behind is what creates the crashing soon.
Geoffrey Zoref Incorrect, the crack is caused by the loop in the whip moving down the length of the whip faster than the speed of sound:
www.scientificamerican.com/article/true-cause-of-whips-crack/
Respectfully: look up "on the dynamos of a bull whip"
also, the link that you cited also says that it does break the sound barrier, but that it isn't the entire reason for the crack only part of the reason for the crack only part of the reason for the crack.
Well, as long as there's the "cracking" noise affected, it really doesn't matter. If the crack was really caused by the speed barrier broken and the crack occurred for them, then they should've broken the sound barrier when they did it.
that's not how you crack a whip, but whatever floats your boat😂
This is what happens when you give people a whip whose whole whip cracking education rests on flicking eachother with a towel
Also, it should be noted that he said "two thousandths" which is not 1/2000th as you mis quoted... two thousandths, or 2/1000 is 1/500th or 480fps.
altitude has nothing to do with the speed of sound. when air is the medium the temperature of the air directly effects the speed. (hotter = faster, cooler = slower) It is not audible but it is measurable.
4.06 - my day started off so well
Did you guys take into consideration the parabolic nature of the whips movement? The ruler should be used as more a reference point than an actual ruler, since the whip didn't follow a straight path.
Round two: Get Adam with his superwhip
I always thought you had to twirl the whip above your head once to get more momentum or is that usually for show?
unless it's a snake whip, it's more about leverage then velocity... also these tests have no clue how to crack a whip
oh my god. he's whipping it in the way they teach you not to whip. that could come back and blind him..
I like how they missed the clearly visible shockwaves made from the whip and the towel.
they should have got one of those magnetic things that tell you the speed of bullets and then put a little bit of foil or wire on the end of the whip, and then got a decent whipper, from texas
Congrats you are now world champion of the world, even jesus is coming down to pat your back, with his statement, "Well job - dramatic pause -, my son"
Yisus guys!! you two should've been those who never did homework on time! Back to school
Use a grid as background and get a better high speed camera.
If you knew how to use a whip, it would have probably worked. Instead you two looked like a couple Apple store employees out there lol
Okay, can I suggest that the reason you didn't catch it is because you weren't throwing the whip correctly to get an optimum crack. You were doing a very simple crack, but it wasn't getting the actual sound barrier. Standing and throwing the whip forward and filming the coil going down the length of the fall would have let you film the actual crack at the end, in a very predictable place. Also frontal shots, and back shots would have shown more as well.
At about 1:18-1-19 you can see the whip quickly break the sound barrier..I noticed the small bit of moisture particles at the end as you would see on a jet breaking the sound barrier..or at least on the edge of breaking it. But either way, pretty cool stuff :)
Wouldn’t, theoretically, a longer whip make the tip move faster because the energy has more time to build up before its released with the “snap”
He sounded like a T-Rex, in super-slo mo when the whip hit him.
3:18 lmao, nice photobomb
This is one of those comments you read before watching the video and just think "WTF is about to happen?"
They were measuring at the wrong time. The whip "cracks" when the fat in in circular motion aka when it is "in" the loop, that is when it is moving fastest.
