Be sure to watch the entire video to see all of the patterns that are created. At the end of the video there are 2 links to watch 2 more versions of the video.
This is a very well known effect that has been performed a countless number of times. I wanted to try and different version by using the black lights and also to add a little production value instead of just simply showing the effect.
The effect works by using a formula that provides the specific length for each string. When all of the pendulums are started at once the patterns will start to form. The pattern resets after about 1 minute. I glued white poster board on the sides of the nuts and used a black light, causing the white to glow.

simplicity + accuracy + creativity = spectacular demonstration.
What?
at times, it looks like DNA spinning around
At 0:55 and 0:58
Reel Hawkins I had the same thought. Surely they here has to be a relation between our dna and wave probability.
D. Ryan no
D. Ryan The shape isn’t even called “DNA” It’s a double helix... you can find it in tons of places... even the strands of keratin that make up your hair
At times also like RNA ;)
The equation looks like this; T=2π√(L/g)
where g=9.8 (approximate acceleration due to gravity on earth in metres/second^2)
"L" being the length of the pendulum string, "T" being the period of 1 oscillation.
if the pendulum string is shorter, the time taken to swing from one side to the other and will be shorter, this can explain the different time the swinging actions take, giving the wave like effect.
Mass, height and shape are not important as air resistance is negligible in this scale of experiment guys.
You're a genius.
In short, T² is directly proportional to L.
I know the equation but it is not complete, it does not take into account the effect of the resonance with the adjacent pendulums, in the case in which the pendulums are in ferromagnetic material, it is also necessary to take into account the magnetic fields which mutually influence each other .... real situation is much more complex, the equation you mentioned applies to a single pendulum sufficiently far from other pendulums, placed on the equator at 4 meters above sea level, where G = 9.80665 m / s², in a vacuum sealed chamber pushed, at the temperature of 4 ° C and the only force exerted on the pendulum is that of gravity, it is a purely theoretical condition far from the real conditions and would not give an exact result anyway ...
T=2π√(L/g) is only an approximation for an ideal pendulum where θ is so small that sinθ ≈ θ
So confusing
New Sony PS5 Loading screen...
SONY MAKE THIS A THING!!!
+FR - Clan I actually find Xbox better then PS1,2,3,4,fi...oh wait thhat one isnt already out
Yes!
Sony! Please! This would be great!
it will be released soon
Axel Van Eijck hi
I have nothing better to do than watch this over and over yay
Great video! I saved as a favorite to show to my six grandchildren. They're going to love it!
Wayne Schmidt Lucky grandchildren
Awesome! My physics professor showed my class this during a lecture, and I loved it!
That's a real good explanation of the time period of a pendulum being independent of the bob mass and only depends on the length of the string!
Thx for this. It explains a lot of things. :)

I could watch this for hours..
Simple concept, yet a mind-blowing !!
Amazing , thank you.
Wow I have never seen anything like this on my 91 years on earth. Amazing
I'm really trying hard to figure out why 250+ people gave this a thumb down
sad its 429 now :/
446 as of today
This is amazing! Congrats! :)
Eae procópio de 8 anos atrás. Como vai a vida?
@@jotave7358 Ô!... Melhor do que nunca! :)
8 Years ago, jesus chris
Great! Congrats, it's a nice post!
I've seen an old version, without lights. This one is really impressive...
The other two videos of same subject are very good too.
of all of your videos this one I have found to be the most thought provoking, there is just so much going on ...
Love this !!
***** no one says it any more neither should you
This is just NUTS!
All your films are sooo EPIC!
this is the coolest thing my eyes have ever been bestowed upon when i saw this and really noticed all the patterns i was amazed this is truly amazingly beautiful keep up the good work man and make some more stuff like this!
Create a 10 hours version of this!
Why?
abacada seesyou
drugs.
or at least that was my first thought when I saw the video; how I could have watched this for hours when I used to smoke a lot of weed.
it won't go for 10 hours, unless you're in vacuum and the strings are greased up real well hehe
@@blipblop92 lol
What the actual fu*k.
I AM GOING TO ATTEMPT THIS
Nova Hayes I also made a shader based on this. www.shadertoy.com/view/XlXSD8
+Nova Hayes It's just because pendulums have a different period swing depending upon their length. He just has a gradually lengthening bit of string for each glowy bit. Kind of looks like a xylophone, but with strings and masses instead of bars.
Amazing visual effect!!!!!!!! Just Great.
Excellent use of light to demonstrate this motion. Very well done!
very cool
very cool
Our brains make it amazing. We see patterns, waves and we understand it as a kind of order. Maybe there's some kind of order but we can see just lets say 10% of it in this simply movements. The more creative mind the more subjective patterns. you know what I mean.
wow. :)
It's not really our brains, the wave occurs becuase each pendulum has a slightly different frequency of oscillation from the different lengths of string. This kind of order is simply inherent to the universe, or more specifically, periodic motion. We see a pattern because there is one, nothing about it is random.
Kevin Stitely WOW. :O
This is one of the coolest videos I have ever seen!
that was amazing and profoundly moving at the same time. Star
I have nothing better to do than watch this over and over;)
You always have the best soundtracks ever! ♥
one of the most beautiful things i've ever seen.
I always come back to listen to the music.
It brought me back to 2014...
First time I've been mesmerized in my life!
this illusing is amazing and the music makes it that much better
Saw this originally in 2011, and now, in 2016, still amazes me. Awesome
How about now in 2023?
Watching this in the new era where Hamilton-Ferrari is a reality (2025).
first video i saw of yours, its the one that made me subscribe and im glad i did. happy 200th video!
I always come back to this video for the music
Woah!! My brain is BLOWN! how is this possible?! They were all released at the same time!
The Blender!ZER The longer the strings are the slower they swing. It's that simple.
loved it! great for my daughters science project.
Beautiful...
Just beautiful
This is amazing. I thought of doing something similar with bowling balls and steel reinforcement rods out in the backyard, you know, one of those executive toy ball bearing clicker novelty things, only on a much bigger scale. This kid who lives down the street from me actually built one and got it swinging, but he stepped in between it and they had to take him to the clinic.
It's dancing with me. It's like this incredibly benevolent force that wants me to know that there's no reason to be afraid. Sometimes there's so much beauty in the world, it makes my heart burst.
honestly, what u do is so awesome!
it's so cool how it goes from one wave to multiple and back to one :D
That was truly beautiful.
Me and a friend were thinking of doing this as a science project for school. Thanks for the video.
omg that looks pretty awesome
i am definitely making one! I dont know how i could have lived so long without one.
The symmetry is beautiful
AWESOME! Absolutely brilliant!!!
that looks insane!
The song is so cool too, man.
this is incredible!
Very Cool Effect
this vid makes me smile
best illusion by brussup yet
ok bruss... that was just so cool... great music mix too! Emily
a hundred of these would be freakin epic!!
What a great video. Nice job
Never thought the period of a pendulum could be put to such cool effect. Thank you so much physics.
Great effect!
Its beautiful!
This is awesome!
You made my day!!! Very cool
BEAUTIFUL
dude that's amazing
damn, you should start a museum/exposition with all your illusions/science/art! I'm sure everyone would love to pay entrance to see a lot of your work in real life.. I would!
That was amazing! You should make a bigger one with them on fire! Props brusspup!
this is really cool
That was awesome!
That looked beautiful :D
You, sir, are a genius.
omg thats really awesome nice job
wait so you take boring stuff and turn it into some one the coolest shit i have ever seen? i like this guy.
It’s an amazing effect! Is it going round and round or what? Brilliant but I doubt I have the patience to make one!
I am hypnotized now.
this is the greatest thing ever
I watch one video and that's all it takes for a subscription. Damn that was cool.
That.. Was... AWESOME!!!!! Because of Brusspup I'm starting to acually LIKE science.
WHATTTTTTT THATS AWSOME
Your music is great
Mind BLOWN.
that's so beauty!
Very ingenious!
best thing that ive seen. awesome trick.
Thats amazing!
Holy crap that is awesome!
THE GREAT AND POWERFUL TRIX- I mean, BRUSSPUP
@GefroreneSeele
Much thanks man! Wish I had known about this before. Thanks for taking the time to point it out for me:-)
Legends say that they are still waving to this day...
amazing...give inspiration thanks for this friend
Wonderful. Thank you.
Wow that's amazing!
wow!! i loved this!!
Fascinating!
This is sick!
beautiful
Nice idea for glowing
a beautiful merge of math and rt brain.... great job !!!!
I liked this video before I even watched it cuz I knew it was going to be amazing.
