It must be kids as I saw the Stroboscopic effect in science class at around 12 years old. These guys must have been asleep when their teacher showed it to them, basic science. Having said that, the water effect with the speaker was a nice demonstration......
Planet Unknown you must be the most gullible person if you think there reactions are genuine. everything about there reactions is fake and fake equals annoying.
never learned this as a kid, only observed. (However the water one I didn't have much of a clue one). Sadly teaching kids about this isn't exactly put onto tests and are in the school curriculum...
Matt Burfield Teacher didn't show it and didn't explain, they didn't show it full stop. I observed it from TV, video recordings, and video gaming and other media forms where FPS and such are a thing.
because the BBC doesn't take Brit Lab seriously anymore. Their parents feed them a lot of sugary foods with artificial colouring. Soon they'll be roughhousing and someone will end up crying and have to go home. Typical children's party.
A slight over reaction from both bystanders but the female is particularly annoying. I mean this is not earth shattering stuff, neither is it an American talent contest. Stop it please.
Maybe she is acting, but what is wrong with a childish fascination about something new, something cool? Tesla use to say that moments when he finds something out must be better than sex, though he never had one. You lost your inner Peter Pan pal, I feel sorry for you...
Awesome video, I just had to use it to answer questions about the wagon wheel spokes effect (why the wheel is turning backwards and/or not turning at all) of my 10 year old and 7 year old sons.
With a ceiling fan, a darkened room, the strobe feature on your smart phones flash light - when the fan is on medium speed use the strobe to watch the fan seeming slow down or go in reverse
Remember this is a show for kids to get them interested in Science and finding out why things work. If you look at any kids show, they emphasise reactions to get them excited and yes, most things are simple. However, simple often is fun. Think of the simple aspects of putting an Alka-zelter tablet in water and oil to make bubbles. Not university science, but it it fun, makes kids think about what is going on and even adults love it. At the end of the day it is about having fun, exploring science and getting kids interested to explore NOT winning Hollywood cinematography awards and best actor awards...... relax and enjoy the simple wonders of Physics:)
They could probably strobe led lights in a dark room, and repeat the same experiments without using any cameras. That's basically how manual inspection of rotating tires is done, persistence of vision.
Enthusiasm is a little much but this could be great for getting kids interested in science. Our entire world deals in frequency & mathematics so this would be a great jumping off point for students.
if you find this amazing and if you see this for the first time then i bet you are either from mars or you are born before the end of WWII... i really dont remember why i subbed this channel but now i know why i will unsubscribe...
HA, I sued when I saw a years old video from this channel hosted by James May, the one with the cross over with Vsauce, never watched another video since then to now, and now I realise I have subed to the wrong channel.
***** it depends of the camera FPS and the flashing of the strobe light... the frequency of the flashing of the strobe light is slightly different than the frequency of the sound that is used to vibrate the pipe... you get the same effect when you take a video of airplane propeller... you cant see this effect with eye you must watch it with a camera...
***** the first time i saw this effect was early 2000th on TV and there was no explanation but my common logic solved how this works years before i saw it on youtube with explanation... "could we set up the experiment so that we could actually see the same effect without a camera?" yes you can, if you do the experiment in dark room with only the strobe light as a light source yes you will be able to see the efect directly with your own eyes (tho never seen such example nor i know anyone that did this, but you see using my common logic i know that it will work)... use your brain and you will see that you will be able to understand many things that have no explanation... if you rely on someone else to explain them to you then you live in a box which will be your blockage to progress outside of it...
But I guess this effect is only for the camera and not to the naked eye. For the naked eye to see this, you will need a stroboscope light which switches on and off at 25 Hz.
Ran into this clip. Watched it. Was not sure this is a drama or science program. Felt like leaving some message. And then read the prior messages. Found that 9 out of 10 talking about the same thing as I wanted to say, and then reached the conclusion: the producer of this show needs to improve or he/she just wants to intentionally irritate the viewers.
At least one of these three is high... they must be... No one over the age of 12 gets that excited from a "Mr Wizard" demonstration. ("Oh WOW... OH WOW!!!" please, get real)
That was sweet! So to add to a previous question in the comments, these shows that these are clips from, are they all on BBC? Or are there now like BBC Science, etc. .... Because if not someone should probably get right on that little money making idea :p
Really? You never seen a helicopter's wings in movies? They always look like they are moving backwards slowly. This isn't "some we have NEVER seen before". This is pretty basic shit, yet they hype it up to being something new and spectacular.
The bit that he hoped nobody had seen was the part at the end with the water being vibrated using the speaker. Although I do agree that it's irritating when they feign ignorance to things you'd expect people doing the stuff that they do to know.
***** Yeah, I get that, but even that isn't new or special. It's been seen and done to death. Overall pretty disappointing. Made me unsub. The videos with those 3 are just as unimpressive as ever. Last time they giggled at some gunpowder blowing up. Like, come on.
Your sight is not a continuous stream of image or data either. The light information in your eye is integrated (summarized) over some time, and then interpreted by the brain. So essentially, you are seeing individual pictures as well. Same mechanism applies, just with higher speeds.
Did the guy editing this just get bored at the end........CUT
Its cut from a TV show
Please become a meme: "I LI'E THA', I LI'E THA' A LO' "
She's talking baby. LOL
That turned my stomach as well.
Daniel | FS Hand It's a Forrest Gump reference from Dumb and Dumber so technically it already is a meme. Jen-ny!
LMAO, I thought the way she talked was strange, can't be bothered to pronounce her 'T's and she's on TV!.....
+Bruno Lazaro You mean cockney?
That water wiggling part was actually very very cool!
That abrupt cut at the end though...
yep, every dawn time
strangely, it also happens at noon
I've never seen it happen at dusk however. Can anyone confirm it happens at dusk?
always lol
@@learomero6785 lmaoooooo @Eldeeff
level of enthusiasm. a bit on the high side.
i really cannot tell if if is aimed at kids or adults
I agree, to whom is this programs intended audience, kids or adults? I'm going to guess at a new set of the public, kidults.
LWR II Kidults, what a word.
There's a film by the name of kidulthood.
It must be kids as I saw the Stroboscopic effect in science class at around 12 years old. These guys must have been asleep when their teacher showed it to them, basic science.
Having said that, the water effect with the speaker was a nice demonstration......
That was a good film.
unsubscribing because of the poor camera work yet again and the annoying hosts who over act everything
Planet Unknown considering my comment currently has 27 thumbs up then no I don't think its just something to do with me
Planet Unknown Rightio mate!
The effect with the camera is widly known and they are pretending they have never seen anything like that before.
+Planet Unknown you need to tune down the level of surliness, mate
Planet Unknown you must be the most gullible person if you think there reactions are genuine. everything about there reactions is fake and fake equals annoying.
"Acting amazed at basic stuff we learned as a kid" Lab
never learned this as a kid, only observed. (However the water one I didn't have much of a clue one). Sadly teaching kids about this isn't exactly put onto tests and are in the school curriculum...
R4V3-0N So the teacher showed you it and didn't explain it? Just moved on.
Matt Burfield
Teacher didn't show it and didn't explain, they didn't show it full stop. I observed it from TV, video recordings, and video gaming and other media forms where FPS and such are a thing.
"I li'e tha'! I li'e tha' a lo'!"
LOOL
Yea you caught that too? Reminded me of Lloyd from Dumb and Dumber.
hahahhaha
Why are they acting like 11 year olds
because the BBC doesn't take Brit Lab seriously anymore.
Their parents feed them a lot of sugary foods with artificial colouring. Soon they'll be roughhousing and someone will end up crying and have to go home. Typical children's party.
11 year-olds won’t do that.
love the enthusiasm - that's how i want science to make everyone feel!
A slight over reaction from both bystanders but the female is particularly annoying. I mean this is not earth shattering stuff, neither is it an American talent contest. Stop it please.
john howe no it's not it's more like a British talent contest.
Maybe she is acting, but what is wrong with a childish fascination about something new, something cool? Tesla use to say that moments when he finds something out must be better than sex, though he never had one. You lost your inner Peter Pan pal, I feel sorry for you...
Skateboarding cameraman with parkinson's is back in the mix!
I LAIHK THAT I LAIHK THAT A LAT
Lol. But more like: I LA THA, I LA THA ALA.
Her reaction is priceless 2:58
She's annoying
Can you please pay some proper camera people? I see comments all the time about the cmera work and yet you guys won't fix it. What's happening there?
After watching the video through I too might unsub I think. This catering to hipsters rubbish is getting old.
MPAH1981 k, bye!
/waves
This can also be done with strobe lights. In the strobe light method you don't need a camera to see the effect on the water.
You guys are having WAY too much fun! Secure the happiness! LOL! Kidding, I love it!
The Best Actor/Actress Award 2016 goes to...
Derek Leung ..... me
i used to love this show as a kid!
1:50 lol what xD
Four words: Zoom out, use tripod.
I searched This effect After Watching In TV And Same Video Came 😂😂
This is not a Stroboscopic effect! The water is going back because it doesn't like the way they are acting.
I am actually pleasantly surprised at that.
That water part was preetty cool.
Please sack the old man and women
I like how excited she gets
Best bit is at 2:49
do you mean their facial expressions,,,, because it really is prime physical comedy
no, I mean the most impressive part of the video
Carlos Chau 2:59 the hell girl
I love science.
I agree with the others in that acking the videos off before they're finished is seriously annoying
Awesome video, I just had to use it to answer questions about the wagon wheel spokes effect (why the wheel is turning backwards and/or not turning at all) of my 10 year old and 7 year old sons.
Don't need a camera you get the same effect looking at car wheels through some fences

Proud of you sir
I was expecting more scientific reasons than that
the idea with the water was pretty inspired. Good stuff!
very good, very cool!
VERY GOOD
THIS IS EXTREMLY COOL AND AMAZING EXPERIMENT!!! :D
these camera angles are so intense I feel like liam neeson is about to tackle one of them
Other speeds at which wheel could seem to be stationary was 3,6,12,24 fps, science can make anything possible
2:51 OMG
That effect looks even weirder on a helicopter.
Nothing wrong with greg, brilliant presenter. Not sure on the other two though..
Excellent. Got to try at home.
Wow amazing.
Did they drop acid?
Wait, why am I watching this?
I don't get this channel - is it it's own education channel or snippets from other television programmes??
It's a mix of videos made for the channel specifically and videos taken from various educational BBC shows (BBC running the channel).
Did you make a plan to show the surprised face of the lady or that scientific event? Because only the cameraman showed the lady with her mouth open
They could probably strobe led lights in a dark room, and repeat the same experiments without using any cameras. That's basically how manual inspection of rotating tires is done, persistence of vision.
The stroboscopic effect is soooo satisfying
Thumbs Up for the Video team who faced the challange of not caching the wheel stop at the same time with the on stage camera. :)
Amazing work
Great show, super science.. Liked it
@Brusspup did it some time ago as well :)
"I LIE THA ILIE THAT A LO" "YOU CAN STOP"
That girl just said, "Ah lie that, Ah lie that ah law".
I used to make the ceiling fan go backwards with my eyes. When I was little in bed. Look at the fan and keep blinking.
Ice Age Sid. 💀
beeing surprised by the result of this primary-school-level science, should disqualify someone from beeing a host on a "science-show"
"Something you've never seen before" apart from on every wheel of every car. James May is really the linch pin of this channel.
Thought that was sid from ice age in the thumbnail.
How is this Video so clear at 360
DAAAAAAAMN! Didn't know you were a sorcerer, GREGGAYYYYYY! :) Sweet video!
I've seen this effect in person too. I guess that means the tire was spinning faster than the image in my eyes could refresh.
I was preparing for my exam, searching for a explanation video and I found this👌
Its like the adventure of three kids who look like adults...or is it the adults who behave like kids?
lol i worked this out when i was a kid but its really cool to see the experiment
I was like.. WHOOOOOOOOOAAAAAAAA...
Greatest thanks to the developer of this demo...
"i lai tha, i lai tha a lo" why's that so funny to my russian ears
this show just reminded me why i havent watched any tv in 6 years or so
Enthusiasm is a little much but this could be great for getting kids interested in science. Our entire world deals in frequency & mathematics so this would be a great jumping off point for students.
Why did he use the "Western" example, hasn't he ever seen a car? Ahahahah
when we watch the actual disc it makes no difference because it is still on camera LOL
Cool
Are these filmed in a cupboard? Shots are always extremely close up, AND shakycam. It's not a great combination.....!
Damn these reactions are epic! like: *'Ahhhhhhh! What's happening!?! I CAN'T HANDLE THIS SHIT!!! AAAAAAH!!!'*
if you find this amazing and if you see this for the first time then i bet you are either from mars or you are born before the end of WWII... i really dont remember why i subbed this channel but now i know why i will unsubscribe...
James may
HA, I sued when I saw a years old video from this channel hosted by James May, the one with the cross over with Vsauce, never watched another video since then to now, and now I realise I have subed to the wrong channel.

that is REALLY good! it's really good! yeah
why the abrupt end ??
I like Fran Scott, she is cool
I've seen this before (not live) but the water effect's better with strobe lights.
But I guess this effect is only for the camera and not to the naked eye. For the naked eye to see this, you will need a stroboscope light which switches on and off at 25 Hz.
not sure if this was made for kids, but certainly looks like it was filmed by kids handholding camcorders. what a mess.
I've always wondered why if you look at a car driving, why the wheels look like their going backwards... now i know
That’s always good 😂😂
Ran into this clip. Watched it. Was not sure this is a drama or science program. Felt like leaving some message. And then read the prior messages. Found that 9 out of 10 talking about the same thing as I wanted to say, and then reached the conclusion: the producer of this show needs to improve or he/she just wants to intentionally irritate the viewers.
then how come we dont see the plate the same as the tv screen??
At least one of these three is high... they must be... No one over the age of 12 gets that excited from a "Mr Wizard" demonstration. ("Oh WOW... OH WOW!!!" please, get real)
As that the "feel good inc" bass line at the build part or is it just me...
That was sweet! So to add to a previous question in the comments, these shows that these are clips from, are they all on BBC? Or are there now like BBC Science, etc. .... Because if not someone should probably get right on that little money making idea :p
they REALLY, REALLY NEED an outro at the end.
thats.. a bit too basic, but okay
Really? You never seen a helicopter's wings in movies? They always look like they are moving backwards slowly. This isn't "some we have NEVER seen before". This is pretty basic shit, yet they hype it up to being something new and spectacular.
Razid they explicitly say at the start that they HAVE seen that kind of stuff at the start. it's the effect with the water wave they haven't seen.
Pro Haggis Then it's pretty silly to ask them if they want to see something, that they have never seen, before that.
The bit that he hoped nobody had seen was the part at the end with the water being vibrated using the speaker.
Although I do agree that it's irritating when they feign ignorance to things you'd expect people doing the stuff that they do to know.

haha that's a good point actually fair enough man, the gun powder thing is also very true!
insane
Resonance
i see wheels do that without a camera
Your sight is not a continuous stream of image or data either. The light information in your eye is integrated (summarized) over some time, and then interpreted by the brain. So essentially, you are seeing individual pictures as well. Same mechanism applies, just with higher speeds.
Can you guys better explain why it's happening
for something you see everyday with car wheels, this isnt really cool new and amazing..
