Yooo! That also blew my mind as well, i had no idea the notes could get so far apart. That leads me to wonder if you had a shape that produced 4 distinct modes, could you tune them to a chord? I wonder how feasible it is, the tuning would be relatively simple but what shape produces 4 modes that are all distinctly tunable while remaining simultaneously excitable
I immediately thought of overtone singing when I saw this which is an eastern method of singing two notes at once, first popularized by Richard Feynman in the west, but it uses the same principles, with the added Bernoulli effect occuring in the trachea vibrating to create sounds and the mouth and tongue creating vowel sounds simultaneously. I've heard it takes YEARS of practice to create those sounds distinctly, but I was mesmerized by the effect! Nice video, Matthias!
Of course it does Yonatan! I think next time I notice something I'll make the effort to wonder more - I guess, that's how children think, and as you get older you kinda get fatigued; but being older, you have more willpower to do something about it.
I knew it was a pot.. but I didn't know everything else that happened in this video beyond "if you hit metal things they vibrate and make a sound". Now I'm wondering how you'd make one that sounds a 6th interval rather than this major 3rd to make a really unsettling door chime :)
I don't know the physics well enough to say for sure, but by simple induction, it seems like: * A perfectly round cylinder sounds a single note * A real-world not-quite-round one sounds a wavery note (two frequencies very close together) * Making it less round in this specific way causes the two modes to diverge more until they form two distinct notes * Perhaps diverging further from roundness would cause it to diverge further in pitch? In other words, your 6th-interval bell could perhaps be made by just grinding a little more. You might need to start with a thicker-walled cylinder, to avoid grinding through it. Or, you could also build up the other mode by adding on strips of material there-epoxying them on would work (the connection just needs to be reasonably rigid), but just welding a bead in those spots might add to the unsettling effect (by making the shape irregular in other ways and adding lots of other, weaker modes to the overall sound).
*le gasp!* no the vibraphone does NOT do exactly this, it periodically muffles the output that's all. THIS would be much more impressive. Maybe marble machine Y or Z
Really enjoyed this video Matt. It’s the same when tuning a guitar using harmonics. You hear the two tones until you get very close to the same note. Great video. Thanks
This is great. Even bandsaw blades have their appearance... Michael Faraday: "The Chemical History of a Candle" Matthias Wandel: "All physics inside a bandsaw"
Any normal person coming across this video of a guy making a bell in a woodshop would be thoroughly confused, but I think this is about what I've come to expect from your channel. I always love the explanations.
Really cool experiments and simple explanations. In university we also had the chance to make such experiments with real bells in a "quite room". Pretty cool and much more interesting than expected. We also learned that the weight of the object that you hit the bell with affects their noise. Only the heavy weights can excite the low frequencies and make the well known bell noise, but they also wear and destroy them quicker.
This is so great. This could have been a really complex boring thing to explain, but you showed the theory and practice and proof in a fun way with everyday items in only a few minutes. Truly well done!
This is fascinating on many levels! These vibrational modes (especially the band-saw blade) remind me of an electron's "orbitals." (an absurd term since they do not orbit, but do obey laws of standing waves in each shell or quantum number from rest-state and above.) When one set of nodes is silent, the others vibrate. The more one part of the band-saw blade vibrates, the less the other four nodes can. Conversely, when those nodes are silent, like nodes of standing waves, the others are moving. When one wave happens, the other can't. The more we know about one wave, the less we know about the other. That agrees perfectly with the Schrödinger equation, the uncertainty principle and Pauli's exclusion principle!!! Further, the vibrational modes are similar to the intrinsic angular momentum or "spin" of electrons. Again, "spin" is an absurd inaccurate term, but it does explain the electron's Up or Down polarity when observed, as in the Stern-Gerlach Experiment. If vibrational modes of electron orbitals are the cause or effect of their intrinsic angular momentum, then these vibrational modes give a mental picture of such phenomena on the quantum scale! Though quantum mechanics is non-intuitive, these examples could be used for classroom demonstrations to help students comprehend such peculiar and interesting phenomena of physics. Matthias, your unquenchable curiosity and experimentation may help us unravel deeper mysteries than the sound of bells! Even if it doesn't, Kudos Sir! Always educational and entertaining!
Love your woodworking content, but I think my favorite videos of yours are these explanation videos. You have a talent for taking these kinds of ideas and explaining/demonstrating them to make them accessible to me. Thank you!
Absolutely love your videos and inventiveness. At the end of the video, with you continuously striking the bell, I realized you're still just a curious boy at heart with the initiative, ingenuity & daring to do most anything you set your mind to.
If you show a flat sheet (circular, rectangular, square, best painted black) and excite many of its eigenmodes (proper frequencies) by hitting it in the right place then you can make the "nodes" (locations that do not vibrate) visible by putting fine saw dust on the sheet and watch it concentrate in the nodes. That way you could bring wood (saw dust) back into your physics classes... ;-)
You are so clever. You always surprise me because you find very simple and visual ways to explain very complicated concepts. You could be a good teacher. You could get paid by colleges or universities to work on physical explanations of physical problems in many topics. Problems I hardly understand and think about since years, you illustrate them very visually in seconds.
That's very cool! The same effect gives the distinctive dissonance of a spoon on a coffee cup rim from the cup's handle giving one of the modes of vibration more mass.
It's funny how I still manage to learn something when Matthias explains some physics. Truly an original take on things, not often encountered. The quality of these films is just of the chart!
I was surprised at the end where the ground down sides were different tones and at the spinning tone! Thanks for doing the experiment. Will you be making a spinning door chime?
What I liked the most is the "child's enthusiasm" in you eyes Mathias experimenting this stuff. Made my day, was laughing with my full joy :) thank you very much
I have this strange ringing in my ears at the end of your clip. Cool demonstration and explanation of the physics. I really like how the osolation changed as you spun the bell.
18 o'clock isn't that much creepy. It makes me fondly remember Don Herbert aka Mr Wizzard. Thanks Matthias www.smithsonianmag.com/smithsonian-institution/meet-mr-wizard-science-guy-inspired-bill-nye-180956371/
How long did he continue striking the bell but edited it out for time?! xD lol, but no it isn't creepy. It's that WONDER that he has that prompts him to be way more inspired than the average bear
Hey Matthias, professional concert triangles are made to produce two tones! Striking it on top will produce one tone, and striking it on the side will produce another. The richest sound, however, comes from striking at a 45-degree angle, where both tones are present. I enjoyed your video!
The spinning steel tubular bell sound is very hypnotic. Knocked me right out the first time I watched it. To be fair, I was also very tired at the same time.
My music perception is so crap I only belived it was a major third after seeing the piano lol. Super cool, is that why instruments sound different when stricken in different places like the body of a guitar or a cajon?
You're right. I guess that would depend on the phone, it's not easy getting consistent results with these apps, but smartphone mics are getting better, a Samsung Galaxy S4 (which is not new at all) has two mics on the top and bottom edge of the phone, and is my best audio recorder on hand, even when I don't have an external mic. I guess you'd need to test the app against something properly tuned, to make sure it's calibrated right, before relying on it, you're right. Good point. Cheers!
This is a great musical experiment! I made a two octave set of chimes using steel conduit. Each pipe was cut over size and material removed until correct note sounded.
I asked myself why the 2 mode frequencies in the steel tube are a clean major third apart. But it quickly made sense: the wavelengths of the two modes are equal to 1/4 and 1/3 of the circumference. What happens if you grind a circle around the circumference somewhere in the middle of the tube? Are you exciting modes that are resonant with the length of the tube?
I think you would introduce another mode of oszilation into the tube, might sound interesting, or due to some other weird physics it might make it just sound dull or dead and make it not keep oszilating for such a long time.
Paul - if you did that you would lower the fundamental. On marimba and vibraphone bars you lower the fundamental in this way to tune it closer to the second mode (heard when holding the bar at its center then striking). This is necessary because free vibrating bars of constant thickness do not have harmonics that are in tune with the fundamental. That is why the bars have an arch cut on the underside; it lowers the fundamental but not so much the 2nd harmonic. With a lathe and solid round bar stock one should be able to tune the 1st and 2nd harmonics in a 3 dimensional manner. Also interesting is that for each tubular material type there is a length (frequency) that will be self resonant with the open air column inside the pipe. This makes it sound super loud!
He kind of already did. He wrote a program to create the layout of gears. Martin from Wintergatan uses that program for his gears. Martin mentioned that on several occasions.
Fun fact: I Emailed Matthias already before building the first marble machine and asked if he could help me, he gave some great advice on video making that i´m still thinking of today when making videos. And it was his channel that sparked the inspiration for me to take my building to a more serious level than it was before. I was always building stuff but after watching Wandel i wanted to only build stuff.
Matthias, great stuff. Do the same at the rim of a mug set on a counter top. The handle weight will cause the same phenomenon. I’m a percussion professor. This is right up my alley.
One of your coolest videos to date A couple musical notes: You and I have the same model piano; a Yamaha U7 I used to play in a hand bell choir. Hand bell choirs take advantage of those aspect of bells all the time; swinging and rotatating the bells, etc., to get various sound effects.
I remember your fantastic work and website from years ago. Thank you for sharing your experience and brilliance in video form. My kid loved this video! I think the spinning bell is reminiscent of a rotating Leslie organ amp.
Hi Matthias ! Your videos are really enjoyable. The way you explain in detail really nice. I do not know about others but I am learning a lot from your videos ! Many many thanks to you !
I wouldn't have believed you could construct a tubular bell with two notes a major 3rd apart! Very well done, and explained - thank you Matthias. New possibilities for wind chimes, maybe?!
Thank you for all of your videos. This one though was especially fun. I watched it with my children and I feel like we all learned something new and interesting. Thanks for the inspiration.
Physics! Thank you for the wonderful explanation. And once again, your clamps arranged to look like a massive spider still catch me out in every video.
I'd really like if you did more videos like this. I have a more intuitive feeling of vibrational modes after this video than after spectroscopy lectures.
Some say he's still ringing that bell
Legends*
He looks like a mindfulness guru with OCD
He's called THE STIG
Must have been caused by self-hypnosis
as of june 2020, i can still hear him.
Very cool. Liked the tuning via angle grinder.
Yooo! That also blew my mind as well, i had no idea the notes could get so far apart. That leads me to wonder if you had a shape that produced 4 distinct modes, could you tune them to a chord? I wonder how feasible it is, the tuning would be relatively simple but what shape produces 4 modes that are all distinctly tunable while remaining simultaneously excitable
@@eqwerewrqwerqre sounds like a good experiment to find out.
I love the way you explain complex things in easy to understand and entertaining ways.
Great teacher, and very insightful! this is how teaching and learning should be exersized!
*exercised (I'm a different kind of teacher)
RubixB0y, you forgot a comma, and a period.
Oh, a teacher, I am not. Just your common variety grammar troll. (Not really).
Spaceman Rick, if you actually knew about grammar and punctuation, you'd be cringing at your own comment.
That's how you know someone truely understands something. If someone can't explain it simply, then they don't have a good understanding of it.
I immediately thought of overtone singing when I saw this which is an eastern method of singing two notes at once, first popularized by Richard Feynman in the west, but it uses the same principles, with the added Bernoulli effect occuring in the trachea vibrating to create sounds and the mouth and tongue creating vowel sounds simultaneously. I've heard it takes YEARS of practice to create those sounds distinctly, but I was mesmerized by the effect! Nice video, Matthias!
You just answered an interesting question I was never clever enough to ask.
Thanks!
It was one of those things that I noticed before, thought it was weird, but never actively wondered. Does that make sense?
Of course it does Yonatan! I think next time I notice something I'll make the effort to wonder more - I guess, that's how children think, and as you get older you kinda get fatigued; but being older, you have more willpower to do something about it.
acoow I agree, but I take exception to the statement that they don't dissipate.
"This isn't actually a gong, it's a stockpot"... Well well well, Matthias 1, Everyone watching 0
I knew it was a pot.. but I didn't know everything else that happened in this video beyond "if you hit metal things they vibrate and make a sound". Now I'm wondering how you'd make one that sounds a 6th interval rather than this major 3rd to make a really unsettling door chime :)
That was more to let you know that he knew that you knew it was just stockpot and not a gong. Just to be clear!
I don't know the physics well enough to say for sure, but by simple induction, it seems like:
* A perfectly round cylinder sounds a single note
* A real-world not-quite-round one sounds a wavery note (two frequencies very close together)
* Making it less round in this specific way causes the two modes to diverge more until they form two distinct notes
* Perhaps diverging further from roundness would cause it to diverge further in pitch? In other words, your 6th-interval bell could perhaps be made by just grinding a little more. You might need to start with a thicker-walled cylinder, to avoid grinding through it. Or, you could also build up the other mode by adding on strips of material there-epoxying them on would work (the connection just needs to be reasonably rigid), but just welding a bead in those spots might add to the unsettling effect (by making the shape irregular in other ways and adding lots of other, weaker modes to the overall sound).
Stephen, That busted me up! You can't even call it dead pan humor because he's making them sing :P
John Di Francisco oh no you beat me to it. Definitely deadpan humor.
Very nicely done. You can also twirl a tuning fork, and it will behave like an audio lighthouse. Cool video!
I never knew how this worked, but the bandsaw blade demo was awesome. Thanks for the explanation!
and on that note...
Kntryhart ...I'd say this video is a resounding success!
Bravo.
rim shot.
*hoping wintergatan somehow implements this into marble machine x*
The vibraphone in the first marble machine does exactly this
Frank22 I was thinking the same!
+wintergartan needs to check this out for sure ..
*le gasp!* no the vibraphone does NOT do exactly this, it periodically muffles the output that's all. THIS would be much more impressive. Maybe marble machine Y or Z
Now he just needs to reply to this comment and you can be as happy as can be 😊
My Physics class will love this.
Really enjoyed this video Matt. It’s the same when tuning a guitar using harmonics. You hear the two tones until you get very close to the same note. Great video. Thanks
This is great. Even bandsaw blades have their appearance...
Michael Faraday: "The Chemical History of a Candle"
Matthias Wandel: "All physics inside a bandsaw"
First John Heisz, now you, I wonder who else from my subscription list will pop up here ;)
One of the best explanations I've seen on UA-cam (equaling the Engineering Guys channel). Broken down excellently and thoroughly demonstrated. Bravo!
Beautiful sounding bell! "This is not a gong" had me cackle.
It's great that you are able to explain all of this by hitting stuff with a screwdriver. It really is the ultimate tool for learning how things work.
The hills are alive with the sound of Matthias Wandel!
waah waaah waaah WanBel!
Any normal person coming across this video of a guy making a bell in a woodshop would be thoroughly confused, but I think this is about what I've come to expect from your channel. I always love the explanations.
So is this a prelude to a massive instrument containing lots of rotating steel cylinders that you are going to build ???
i spend 16 years of my life in schools and 7 more years self teaching and i'v never understood one subject like u do .... amazing
Cool video. I've seen shows on bell making but don't think I've ever heard someone explain it like this and physically show it.
Really cool experiments and simple explanations. In university we also had the chance to make such experiments with real bells in a "quite room". Pretty cool and much more interesting than expected. We also learned that the weight of the object that you hit the bell with affects their noise. Only the heavy weights can excite the low frequencies and make the well known bell noise, but they also wear and destroy them quicker.
"No, no, no. Hold your head like this, then go Waaah. Try it again" .... Sorry, popped into my head.
Cool demo, Matthias!
Goodaniiiiight adingdingding! Goodaniiiiight adingdingding!
5! 4! 3! 2! 1!
LMFAO I forgot about that. Loved that skit.
S
Is this the right room for an argument?
I've told you once.
This is so great. This could have been a really complex boring thing to explain, but you showed the theory and practice and proof in a fun way with everyday items in only a few minutes. Truly well done!

All of this man's vids are......... Amazing
Absolutely love your videos and inventiveness. At the end of the video, with you continuously striking the bell, I realized you're still just a curious boy at heart with the initiative, ingenuity & daring to do most anything you set your mind to.
So where is the requisite wooden bell?
Rambozo Clown He made a wooden air ride siren once.
this should totally be possible with wood, yes?
Rambozo Clown
That wooden work.
An engineering approach to a wooden bell. I bet you can optimize the heck out of that. Grain directions and angles and such.
Too complicated
Great demonstration of the forces that cause this, and the sound of the spinning bell was awesome.
Bell-issimo! Bell-tastic! Bell-arific!
Very nice! I never saw someone spinning a bell.
I'm more confused now than I've ever been!
Is Mathias going to join a band?
A ukulele and bell band.
Bell-arific? What a ding-dong.
When the video finishes.... does that make it a bell-end?
I've been watching your videos for years and this is now one of my favorite! Can't wait to get home from work to show to my 6 year old son.
If you show a flat sheet (circular, rectangular, square, best painted black) and excite many of its eigenmodes (proper frequencies) by hitting it in the right place then you can make the "nodes" (locations that do not vibrate) visible by putting fine saw dust on the sheet and watch it concentrate in the nodes. That way you could bring wood (saw dust) back into your physics classes... ;-)
You mean like a saw blade in a wood shop? Now where in Hell would Matthias get stuff like that?
You are so clever. You always surprise me because you find very simple and visual ways to explain very complicated concepts. You could be a good teacher. You could get paid by colleges or universities to work on physical explanations of physical problems in many topics.
Problems I hardly understand and think about since years, you illustrate them very visually in seconds.
Very exciting -- in two directions
This comment resonated with me!
That's very cool! The same effect gives the distinctive dissonance of a spoon on a coffee cup rim from the cup's handle giving one of the modes of vibration more mass.
Please, more like this one, Matthias! You're good at this.
It's funny how I still manage to learn something when Matthias explains some physics. Truly an original take on things, not often encountered. The quality of these films is just of the chart!
I was surprised at the end where the ground down sides were different tones and at the spinning tone! Thanks for doing the experiment. Will you be making a spinning door chime?
Well, not exactly what I would expect from a predominantly woodworking channel, but that was really interesting!
How long until we you fashioning an instrument from spinning steel pipies? I'll give it about a week .... ;-) Great stuff!
He'll make it out of wooden tubes and wooden gears for the movements. You must be new, he only experiments with metal, he fabricates with wood. :)
This is probably going to be Wintergatan's next viral instrument.
Matthias Wandel + Wintergatan = WWWWWWAOWUDGAIHFVBKAHBVFKAJBSd
Kellerwerkstatt That would be a some kind of Hammond Organ... ?
a spinning pipe organ :-) Wandel Organ Factory.
Your videos is the cure for insomnia!Thank you!
From 05:28, quite possibly the creepiest eye movement I have even been subjected to. Well done! :)
Body in the freezer creepy?
What I liked the most is the "child's enthusiasm" in you eyes Mathias experimenting this stuff. Made my day, was laughing with my full joy :) thank you very much
Just going out to the workshop to pluck my twanger.
I have this strange ringing in my ears at the end of your clip. Cool demonstration and explanation of the physics. I really like how the osolation changed as you spun the bell.
Bell ringing with Matthias, love it :)
I work in the field of structural dynamics. Couldn't explain it better. Great thumbs up!
Interesting but needs more cowbell
m4u11 That's too funny, I hope Matthias gets this 😂
I've got a fever! lol
that's awesome.. and also, i wonder if he'd explain the different tones in a cowbell because of the shape.
This is why I LOVE your channel! I've been playing music almost all my life and just learn about this...
Lol the end wasn't creepy or anything hahaha
18 o'clock isn't that much creepy.
It makes me fondly remember Don Herbert aka Mr Wizzard. Thanks Matthias www.smithsonianmag.com/smithsonian-institution/meet-mr-wizard-science-guy-inspired-bill-nye-180956371/
"Stop looking at the camera when you've struck it!"
That look reminds me of dwight
Some say he's still ringing his 2 note dork bell to this day....
How long did he continue striking the bell but edited it out for time?! xD lol, but no it isn't creepy. It's that WONDER that he has that prompts him to be way more inspired than the average bear
Hey Matthias, professional concert triangles are made to produce two tones! Striking it on top will produce one tone, and striking it on the side will produce another. The richest sound, however, comes from striking at a 45-degree angle, where both tones are present. I enjoyed your video!

iShootBandits or professor WaaWaa?:-)
The spinning steel tubular bell sound is very hypnotic. Knocked me right out the first time I watched it. To be fair, I was also very tired at the same time.
My music perception is so crap I only belived it was a major third after seeing the piano lol. Super cool, is that why instruments sound different when stricken in different places like the body of a guitar or a cajon?
Yes major third good sir
Alucard Pawpad if you're interested, you can also use a smartphone for that, now, there are tons of apps that tell you the note that is playing.
You're right. I guess that would depend on the phone, it's not easy getting consistent results with these apps, but smartphone mics are getting better, a Samsung Galaxy S4 (which is not new at all) has two mics on the top and bottom edge of the phone, and is my best audio recorder on hand, even when I don't have an external mic. I guess you'd need to test the app against something properly tuned, to make sure it's calibrated right, before relying on it, you're right.
Good point. Cheers!
the concentration level around 5:40! astounding.. i really appreciate your channel matthias. bits of knowledge such as this keeps me tuned in..
Very cool, thanks for sharing
This is a great musical experiment! I made a two octave set of chimes using steel conduit. Each pipe was cut over size and material removed until correct note sounded.
The result of travelling down an internet rabbit hole?
Nope, first stop.
boy, dont I know it
I figured that you were going to get into a bells shape being the optimal for carrying the sound waves. Thanks for sharing.
I asked myself why the 2 mode frequencies in the steel tube are a clean major third apart. But it quickly made sense: the wavelengths of the two modes are equal to 1/4 and 1/3 of the circumference. What happens if you grind a circle around the circumference somewhere in the middle of the tube? Are you exciting modes that are resonant with the length of the tube?
Oops - I meant1/4 and 1/5 of the circumference. Senior moment.
I think you would introduce another mode of oszilation into the tube, might sound interesting, or due to some other weird physics it might make it just sound dull or dead and make it not keep oszilating for such a long time.
Paul Kolodner .....one could communicate with ET's, maybe even see them.
Paul - if you did that you would lower the fundamental. On marimba and vibraphone bars you lower the fundamental in this way to tune it closer to the second mode (heard when holding the bar at its center then striking). This is necessary because free vibrating bars of constant thickness do not have harmonics that are in tune with the fundamental. That is why the bars have an arch cut on the underside; it lowers the fundamental but not so much the 2nd harmonic. With a lathe and solid round bar stock one should be able to tune the 1st and 2nd harmonics in a 3 dimensional manner.
Also interesting is that for each tubular material type there is a length (frequency) that will be self resonant with the open air column inside the pipe. This makes it sound super loud!
I have watched your channel for years now, and this has to be the most fascinating episode to date
Matthias Woodwell

Mark
as a humble musician : I have to admit not knowing any thing about what You, Sir, are now explaining to us ! Chapeau !Best Regards
Love those sciency videos ;)
i actually never realized the tone would be directional until he showed the demo at the end where he was spinning it. learn something new every day.
I love it when you get an idea that has nothing to do with woodworking, it it ends up being more fascinating and reminds me of physics.
Any excuse to make a bunch of noise, huh?
I learn something from every video. Building one of your bandsaw definitely made me a better woodworker. Thanks for everything Mathias
Do a collab with wintergatan!!
T0NGPU that would be great
He kind of already did. He wrote a program to create the layout of gears. Martin from Wintergatan uses that program for his gears. Martin mentioned that on several occasions.
Bernhard Melitamann i know :) but I mean like really working together, like with the box drum guy.
Fun fact: I Emailed Matthias already before building the first marble machine and asked if he could help me, he gave some great advice on video making that i´m still thinking of today when making videos. And it was his channel that sparked the inspiration for me to take my building to a more serious level than it was before. I was always building stuff but after watching Wandel i wanted to only build stuff.
I think matthias just invented new type of vibrophone
I always appreciate your use of the scientific method.
It must be Friday the 13th.
Matthias, great stuff. Do the same at the rim of a mug set on a counter top. The handle weight will cause the same phenomenon. I’m a percussion professor. This is right up my alley.
Oui c’est belle
Andor_Yoko while it's terrible French, the pun is funny enough :D Cheers!
One of your coolest videos to date A couple musical notes:
You and I have the same model piano; a Yamaha U7
I used to play in a hand bell choir. Hand bell choirs take advantage of those aspect of bells all the time; swinging and rotatating the bells, etc., to get various sound effects.
Dude! You’re a freaking genius! That’s why I like your channel!
I remember your fantastic work and website from years ago. Thank you for sharing your experience and brilliance in video form. My kid loved this video! I think the spinning bell is reminiscent of a rotating Leslie organ amp.
Top comment!? Thanks all!
What a great video! Thanks for this Matthias, your depth and variety of understanding never fails to amaze me.
Hope you guys are having a great day!!
Hi Matthias ! Your videos are really enjoyable. The way you explain in detail really nice. I do not know about others but I am learning a lot from your videos ! Many many thanks to you !
This was a great video. I love when you do these science-ey videos that explain physical phenomena. Good stuff man, keep up the good work!
This is so delightful! I'm going to use this in my physics class when we get to our sound unit. Nice work!
I wouldn't have believed you could construct a tubular bell with two notes a major 3rd apart! Very well done, and explained - thank you Matthias. New possibilities for wind chimes, maybe?!
my eyes literally got wide when you spun the cylinder! that was completely new to me. brilliant!
Thank you kind sir. Your kid(s) are so lucky to have you as a father.
Most random interesting thing I've seen and learnt in a long time! Thanks Matthias =D
The ending was hypnotising!
I love, how you make the coolest bell-video ever using pots, saws and bowls, but not one single bell =)
Hypnotic ending with text plug for self at end.
Well done sir
Isn't it amazing how creative and curious people can derive amusement and fascination from a coat hanger, a couple bowls, a pot, and a length of pipe?
You remind me of my Physics teacher in College. He was the teacher who inspired me most and was a large reason I went into Engineering.
You are truly a mad scientist at heart! Great video even without woodworking!
I've now confirmed I like watching Mattias teach me anything, and not just wood projects :)
I don’t normally comment but great stuff! Your content is consistently great but I love this.
This is fascinating - I like your little forays into everyday physics.
Excellent video. Amazing how complex the simple things can be.
This is probaly the best exsplaining video ive ever seen
Thank you for all of your videos. This one though was especially fun. I watched it with my children and I feel like we all learned something new and interesting. Thanks for the inspiration.
Physics! Thank you for the wonderful explanation. And once again, your clamps arranged to look like a massive spider still catch me out in every video.
Fun one today Matthias! Thanks for sharing. Always a good morning when you post a new video.
I'd really like if you did more videos like this. I have a more intuitive feeling of vibrational modes after this video than after spectroscopy lectures.
Great explanation! I really dig your physics and invention/contraption videos! Keep'em coming!
