You can see bigger versions of this scientific demonstration in museums and science departments. But we think this might be the first time it has been produced as an affordable table-top demonstration.
Fifteen ball bearings hang from a frame, suspended on fine threads. However this is not a version of the famous Newton's Cradle. Here the ball bearings are not touching, and in addition, each ball bearing has a different length of thread supporting it. The time a pendulum takes to move to and fro is dependent on the length of the pendulum. And here we have fifteen pendulums, all of different lengths!
Using the supplied wooden bar, move all the ball bearings to one side, and then move the bar out of the way. All the ball bearings start to swing from side to side. Initially they all (nearly) move together, but very quickly, other patterns start to appear....

I think Tim just hypnotized half of RUclips. Great job, Tim.
Yeah…

I understand the physics of it. But it doesn't cease to amaze me.
_and your voice is amazing_
Sometimes understanding something makes it better
@@theSnicKSA like fight club
I can't see any pattern half of the time. It looks it is searching for pattern then.
SpaceGateX There is. It’s hidden, all the time its just the original wave get more and more wavey. But in between three or more balls line up and create a pattern. But usually two balls are aligned at the same time

When it began to break up it looks like a double helix if you focus hard enough
Yea and then

Almost looks like there’s two rows
One above the other
Bruh I started tripping imagine seeing that while high
PSA: If I ask for this for my birthday next year, DO NOT BUY IT. I would lock myself in my room with it forever, my productivity would drop to zero, and my friends and family would never hear from me again.
I can imagine you locked in your room, talking to it and petting it softly, while firefighters and your family try to negotiate with you through the door.
ITS ABOUT TO GO INTO TWO SNAKES STFU
Win Entity hi
Why would you buy a birthday gift like this for a random stranger on the internet

There -is- was one called Pendulum for those who don't know.

Omg we are some biology nerds!! I seen the same thing 🤣🤣🤣

Whenever I'm sad I listen to this guy's voice. You can't be sad when you listen to him.
true
I knew from start how it works, but as always with physics, damn...! Just how many times it changed formation, and then even ended in almost same pattern, wow!
no its clearly a star wars battle

95Tezza95 Yep, they probably wouldn't have cared about the electrical lights or the digital camera. But an executive desktop toy? Burn the witch! ;-)
Positively hypnotic video! Tim's dulcet tones and the rhythmic waves of the pendulum. All it need was Tim to say "you are falling into a deep trance...."
Apply some special paint to the spheres, darken the room, and turn a black light (or multiple black lights) on.
lol brilliant
I got hypnotized lol, my hand kept bringing the phone screen closer and closer 👁 👄 👁
What a delightful contraption!
They continue to stay in the same line, however the amount of time that it takes for each ball to follow the others path differs as time passes, and eventually it is actually the exact opposite as it was earlier
I'm from 2076 and these balls are still moving
Classic
You should’ve seen my balls swinging!
Hahn Selativ bro there are children watching
I made one of these but bigger for a school project! It's super fun and is so mesmerizing as well!
Can you please say how you made this? I want to construct this

What you name snake is a sine wave
What you name two snakes is a higher frequency sine wave
What you name two rows is the highest frequency sine wave and when everything settles down to a line is called a full sweep or/and zero frequency.
Very very useful toy to have in a physics class.
Never knew watching balls swing can be so entertaining.
I love all the way things Tim does
That's incredibly amazing! Simple but amazing :)
wow
Very pendulum! Such hypnotic :O

Wonderful! Thank you for the demonstration, loved it!!!!
so trivial yet...., I am sold
At first, i didnt understand why they were starting to go unsync-ed but then i realised they strongs are different in longivity
**FACEPALM INTENSIFIES**
they strongs lmao
"strongs" "longivity" "unsync-ed" "realised"
You're the real *FACEPALM*
@@Sam-kj9ui o and i are close together and I have accidentally typed “realised” a lot so I understand that but the others I have no idea how they got those wrong
@@Sam-kj9ui "realised" is not a typo. "realised" is the same exact thing as "realized" so your reply is invalid.
still,that commenter has the most weirdest grammar ever.

Everybody gangsta until the pendulum starts waving
Watching this honestly put me in a trance
Why do I love this so much
so hypnotic
Perfect to watch at night now im sleepy thank😴
Beautiful!
This is so satisfying.

OMG, I can't believe this, this is really amazing. all about are scientific matter.
Wow, am so impressed, this is so nice
RUclips is recomnending this for me 5 years later, okei :v
Well, I wonder why yt recommended it today? Greetings from Germany
they should change the end music to tim saying " yes quite lovely "
This is honestly my favorite physics video
So satisfying
2:00 If you squint your eyes it looks like the balls are all spinning around each other in a cylindrical shape, sort of like a tornado.
Nice, optical illusions.
vissova I'm Asian, so I didn't have to squint
Where can I buy one?
It's a rather curious thing. I'm looking at it head on, and my brain wants to look at it as a cylinder. But it likes to switch which way it's spinning.
Glen Moody-Elias same here. It almost looks like a cylinder of metal balls spinning around like a tornado.
That is trippy

1:32 triple helix wowowowow
Amazing and wonderful!
Beautiful
2:00 looks like DNA
what if you used it in a vacuum with magnetics on each end? Would it swing forever and have I just created a perpetuum mobile? :D
TerrorJesus no its still subject to gravity and entropy.
yesitsvish wait, entropy aside, why would gravity eventually stop it? kinetic energy will just convert into potential energy and then back and forth
but its moving parts are still subject to friction.
also because Newton perpetual motion is impossible.
TerrorJesus What are "magnetics", and why would you need them? If you managed to eliminate friction _completely_, yes, it would swing forever. But you can't. Even in a vacuum, there's friction between the toy's parts (although eliminating air friction _would_ make it swing for a lot longer).
Wow this is amazing
I wonder if it has the same patterns every time....
Propably, yeah
nice
+Nate Landau The patterns could be similar every time but the only way to get it exactly the same would be to release it at the same speed from the same angle every time.
+Nate Landau
Replay the video and find out!
definitely, yes
I gotta watch this when I'm high
Diggity Dom nope bad idea bad idea
beautiful
so satisfying
I watched 3 minutes of this
Welcome to another episode of "why is this in my recommendation ?"
Very good Susan
I shat myself.
TheEpicPlayerz12321 same
I just bought a new R9 290X for my PC. I will give you that and $1000 if I can just make this swing once.
You can use the leaf blower on your card to propel the ball bearings
You can hit the replay button. Give me my money
R9 290xs are shit even from the time you posted this comment :P
like i said it was shit even from the time he posted the comment
These are Super fun! Thank you, we may use these ideas in the Nuclear museum!
I AM AMAZED
Okay, so .. I was curious what would happen if he'd done it like the Newton's cradle ?? : /
+Freya Okami ive tried it doesnt so very much
+Ben Abbott Thanks .. I guess it would work like the Newton's cradle, if the marbles didn't have gaps between them .. XD Hypothetically speaking ..
+Freya Okami Not similarly. The pendulum wave has strings that range in lengths. The ball on the shorter string swings faster while the ball on the longest string swings slower. The newtons cradle will just swing back and forth without any patterns forming except for a straight, swinging line
+Mr_ CookieMonster I don't get it :D Not really good at physics ..
+Matt Miller (R4gn4r0k) That was quite a good explaination .. hehe
DNA 1:56:)
:D
x chromosome is the best chromosome!
Not necessarily DNA, but a double helix.
Sorry no more sex songs
Comments I was looking for
thats very satisfying
Imagine getting high in Tim's house
Oh yeah... Too much fun....😂
Welcome to another episode of
WHY IS THIS IN MY RECOMMENDATIONS
You should be happy obout it
Inforgot about this channel so much i forgot i subscribed
Thanks!
Send this video to Veritasium need to know why they swing at these variations.
The speed of swinging increases as the length of the pendulum decreases.
The time it takes for a pendulum to complete one swing is dependent on the square root of the length of the pendulum. Shorter pendulum --> shorter time.
Daniel O'Connell Well, roughly the square root. There are terms (in a differential equation) that are ignored in a mathematical pendulum that are relevant in a real one. It's only decently accurate for small angles.
Alcesmire Quite right. It's not strictly a linear system.
In this case, it's pretty close to linear. The density of the ball is very high and the mass of the string is very low compared to the mass of the ball. Air resistance will obviously damp it a bit, but I'd say approximately rather than roughly.
I think the visual would be even better if rotated 180 degrees with the camera looking under the balls. No strings in the way.
Under the glass table?
funky3ddy
The black plastic base makes that pointless. Just a low camera angle, that looks between the black base and the balls.
jpopelish
I think it's very easy to remove it, unless it's glued. :)
I believe they use big camera to film this show, so only mobile phone or small point and shoot will work, but even then, I kinda doubt small camera will be able to pick up entire length without wide-angle lens.
Btw, search RUclips for "Pendulum wave (slinger golf)" it should be on blindbrick's channel. That guy made it more stable, so patterns are not as chaotic, and it is much bigger as well.
jpopelish
Oh, and lock the camera focus on the 5th or 6th ball from the camera.
A natural mystic!!!
I can see all the types of waves there!!
