In this video I show my giant pendulum wave and talk about how it works. I built this as a physics demonstration for a kid's summer camp. This is a great project to show to large and small groups and provides lots of talking points about how math effects the real world.

fantastic
Thank you for your videos
@Ix Suomi you're free to try and make something people would watch, but I doubt you have the creative ability
That's cool!!! 👍
Todo lo que hace NightHawkinLight, siempre es un buen trabajo
que nos permite aprender algo. Sigue así, mi amigo!!
This is so good it hertz
You win
Ye it's hertz so much I lost my period
That's it, I'm going Ohm
Hahahaha!!!! Love it!
Brilliant idea to play with a silly parrot during your sponsorship segment. I can never turn it off!
I would love to hear what it sounds like if each nut struck a note corresponding to the length of the string as it reached each apex. I imagine it coming together as the nuts sync up in groups of 2, then 3 then 4. Music is so mathmatical to begin with it might be pretty cool.... or it might just be a big mess!
That's a great idea! Since any contact and friction would interrupt them, they could pass over light sensors or lasers to trigger the notes.
That certainly would be interesting
Do it and post a vid it might get views bro
That is a cool thought! I'd love to see it built in bricks and mortar, but I think it could also be programmed, since this is so mathematical. :)

Can use hall effect sensors as triggers for a digital input transducer hooked to a synthesizer!

Can I just say how much my life would have changed if this guy was my teacher in school? Seriously, Nighthawk, you make this world better just by being in it.
Very kind of you to say
It's funny how when it first faded to the fluorescent bolts, my brain perceived them as fluorescent cubes instead of hexagons.
same
And the wave pattern appeared to turn into a triple helix that was rotating in a 3D manner like a carousel! Blew my mind!
I enjoy watching you and your bird as much as I enjoy the video you are presenting.
it's the only reason i kept watching the sponsorship lmao
I can't wait to get promoted to granddad. The things I'm going to enjoy showing the grand kids (when they arrive) is going to be so much fun. I'm starting building my pendulum rig tomorrow. Thanks.
It'll be nice to know how you take care and train (?) or play with your birb!
Birb vid thanks
Weird that such fantasctically friendly channel has so few views per video. Obviously you can not re-invent Starlite every video, but i enjoy every single one you put out here if only for the attitude. Keep on rocking that smile, you are an inspiration to continue living our often times unbearable pain-filled lives.
A visual representation of math in the real world... not surprising, since math is a symbolic representation of what's happening in the real world.
This Video is Just Nuts! whats even more NUts is the fact that we can build that.
I'm glad you've enjoyed observing my nuts
@@Nighthawkinlight But you didn't just show us how your nuts hang. You showed them swinging in the breeze.
Though I have to say that, in other circumstance, glowing nuts would normally be a cause for concern...
Ben, fascinating and educational!! Additional thanks for your excellent shooting techniques...
Thanks but how did you know my name
О! Похожая эмблема у Адвоката Егора) Обязательно зацените)
This is amazing, down right beautiful. Also, love the music you used in the background :)
Definitely great idea spraying them down with fluorescent. I think more kids will be
motivated to learn something new with videos like these :)
I hope so, that's the goal.
Hey just wanted tell ya your one of my favorite youtubers...i just realised how short life is so i’ll be going around appreciating people more
In remembrance of Grant.
I Absolutely Love it!! Loved your bismuth/magnet levitation vid too 😊
Good choice of sponsors! Love TGC. Awesome video of the pendulum, I love watching :)
Your enthusiasm is infectious. Great video as usual.
So fascinating & mesmerizing to watch. Well done!
Mesmerizing. Can't wait to show this to my wife and kids! Thank you!!
Ok that's really really cool.. Good job, NightHawk!!
From a Hawk to another, amazing job! RUclips creators that are driven by knowledge oriented content will always have a special place on my free time!
Fantastic demonstration! I love how the fluorescent version looks like CGI.
Fascinating and some how strangely hypnotic, brilliant display.
Every time I see this demonstration I am more and more in awe!
Interesting, I didn't realize so much math went into this project. The florescent paint was a very cool touch. Just thinking a mix of other Phosphorescent coolers might of worked worked well too such as Green, Blue, Pink in an alternative pattern.
In theory it would create new interesting patterns not only with waves but with colors.
Anyways another very cool video, keep.up the great work!
Always amazing, and the best one yet. Keep up the good work!!!!👍👍
No one:
The thumbnail:
Perfectly balanced, as all things should be
Thunder Thunder Why do people keep using the overdone joke that wasn’t even funny in the first place?
Can someone please explain the "No one:" thing? It seems like it should be indicating that "no one" is saying nothing, which would mean that everyone is saying something, which makes no sense at all.
@@zoltan1953
I totally agree....... To some extent.
You're channel makes me so happy!
Incredible! Always look forward to these

I love how it starts out like a graceful slithering snake. Then it just starts dancing and morphing.
Excellent video - shows the effect in the most classic way - THANKS
That is nuts gravy.! Fantastic.!
Very nice! I've done ones with nuts, door knobs, Christmas bulbs, and 24 golf balls. The equations get you close, but a lot of small tweeking is needed to get them to all line up at the end.
This is great ! The black light and fluorescent pain was an awesome idea ! I am now gonna try and build one but I think I'm gonna cast my own pendulums out of bismuth for the heavier weight but it also being non toxic so I can bring it with me to do demonstrations!
Thanks for the inspiration !! I've been with your channel well before you started DIY projects and were focused on pyro like your sun and planets shell from a long time ago and than your old video on making the 1.5x3" can shell( that video is what got me into building fireworks)
you're also the inspiration for the DIY videos on my channel, which aren't nearly as good as yours but I'm working on it ! :)
Hope you're doing well !

Beautiful. For me personally, this just shows that whether it be nature or the nature of physics, that there is an underlying order and not just random chance.
That looked amazing I cant believe how convincing it was to me it looked like it was corkscrewing
that eye focus on the bird at the end was cool
Make a 20 min video of the pendulums in motion; a lot of us will watch.
Ive waited a whole month for a video. And u bring me this. Im impressed
Awesomely presented sponsorship segment, going to check it out when I have some free time!
I have to say this is pretty mesmerizing. Well done.
Fascinating and beautiful representation of math.
Love this so much! 👍
i find these so mesmerizing
I have to say you're genious with the bird during the ad. it keeps people watching, not using their brains so they can take in the ad at the same time.
this is just too satisfying!!!
Now I'm tempted to write a visualization for this thing. That looks really cool
This just became my fav vid on RUclips.
How strange--some of the patterns make it look like a 3 dimensional object spinning around. Trippy! Think I'll need to stop at Home Depot to buy some big nuts and string now. :)
I wish you had 1hr episodes on Netflix, your content is always great!
Maybe you would not believe, I subscribe for your politeness.
That was incredibly beautiful. Thank you. I was seeing 3D spirals evolving and changing.
Well played Sir !!! Riveting presentation.
Visually stunning. Very nice scaled up science experiment 😀
Great video! love the patterns.
i love this!! you amazed me once more Ben
Pendulum wave AND bird?! What a treat!
Awesome job on the project!
I seriously can’t believe I used to just think of you as the gun RUclipsr and was not interested. Your videos are really special on this platform. Whenever you do die, you can do it knowing you have changed the lives of a lot of people, and really added value to the world.
It almost hypnotized me.
Thanks for this. Entertaining.

I truly am sorry for the loss of your good ol’ friend and one of our favorite content creators:
Grant Thompson (The King of Random)
1980 - 2019
I remember watching him way back when I was small and I loved him instantly. I watched him everyday and loved seeing such great experiments and high power gadgets.
Seeing such dire and grave news brings many a tears to not just my eyes, but all of ours. 😢
To think that someone as great as Grant Thompson to have passed so early in many of our lives and his own life, is just simply saddening. 😞
All of our hearts go out to Grant Thompson’s wife, children, and other family members and to his friends he made in his youtube career, including you, Nighthawkinlight. ❤️🙏
Another great video never lets me down. Keep thw awesome projects and experiments conong please...
Great video as usual. And good call on including the bird during the sponsorship - I wouldn't have watched it otherwise. I think you should end each video with the bird!! :)
You could attach one end of the strings to guitar tuning posts to allow for easy fine-tuning. Of course that would make this a lot more expensive than it currently is… A cheaper way would be screws with a hole drilled through them.
That's a good idea!
As mentioned in the videos, the small errors accumulate. I wonder if you could fine tune those errors out successfully or if you'd run into too much randomness/unpredictableness before you got that far.
@@doctorbobstone You could use a traditional knife edge pivot and a small adjustable screw to fine tune each center of mass but they are all free running. Maybe release them with electromagnet and resync them every nth cycle ?
Was thinking air currents were affecting the timings.
@@louf7178 Unless there is an actual draft in the room, air will cause mostly random errors that will usually cancel each other out. Of course these will eventually cause the whole thing to go out of sync unless it is placed in a vacuum chamber. An error in the length of the strings on the other hand will keep accumulating because the error is the same at all times. Eliminating this systematic error will allow the pendulums to stay in sync for much longer.
sooo freakin cool man, good work.
Outstanding in the truest sense.
i think this is the only channel where people actually enjoy watching the advertisement at the end. for obvious reasons. well, reason.
Mesmerising!
Thank you for sharing it! Much appreciated, Cheers!
You never cease to amaze me
Fantastic video, thank you 🙏. I love the color green as well .
Its been two years since youtube blessed me with a new NightHawk video.
About damn time.
Two years? Pretty sure hes made more videos since then (besides this one)
@@alexmendelsberg4974 I know he has made more, but this was the first video in a long time that youtube sent me his content.
Amazing! I may try a smaller one. Thanks for sharing
What an awesome video!
You look like the nicest human being possible
@ThomasG10mtn ?
@ThomasG10mtn I'm gonna need you to fuck right off
Is this also about the Poles flipping? In other words, the rythyms/patterns formed by the swinging bolts, reversal, then chaos followed by the return to order.
so is it a triple helix pattern that spins back and forth or am I seeing it wrong?
You are right, extraordinary patterns!!
Those accumulating errors, are they the same every time you start the pendulum or do they change from run to run? Because if they are the same every time you should be able to tweak and tune the lenghts of the strings until you reach perfection.
It could be made more accurate, but at a certain point you would have to get rid of the string and replace with metal rods.
What a swinging video. Cheers!
Very very cool !
Thanks for sharing and take care. 👍 👍
This is so satisfying! :D
I dunno about anyone else but after a period of time I no longer saw pendulous patterns but rotational patterns.
R.I.P Grant Thompson
Great visuals
Very cool and brilliant!
Fascinating.
Great content as always
This was awesome!
I'm _really_ glad I increased my patronage.
Thank you very much!
Awesome!
That's awesome.
Looks very cool, the motion reminds me of a serpent. How big does that type of bird get? Great video!
Mose is full grown
The engineer in me absolutely loves this
Finally a video that gives us some lengths without having to do our own calculations!!! I will try & do some calculations to see if I can but I'd rather start building one first. Can you tell me what size nut you used? Thanks for the video.
That's nuts!
i thought it was kinda neat when the nuts were moving very slow, cool project!
Great man!
