@@satibel I know. A bigger one would have more mass so it would spin a lot longer, and I'm talking about the sound, it would be impossible for it to smoothly transition from a higher pitch to a lower pitch then back to a high pitch again.
@@iTeerRex sugar doesn't actually cause hyperactivity. For that to happen, people would go apeshit every time they eat anything and everything.

MrRedstone pretty sure the sugar does make people more energized and if you ever had carbs like cereal or bread when you’re tired and hungry it gives you energy
Potato Servant the “energy” you feel isn’t the same energy that runs your body. In fact, I’m sure to a certain degree you know this too, if you have too much sugar in your blood (aka your pancreas isn’t producing enough insulin to keep blood sugar at a certain level), you are diabetic. Syndromes diabetes, aka too-much-sugar disease, are quite the opposite of being “energetic”. The “energised” feeling you have is merely your brain producing dopamine when eating food.

I am Vanessa Golston from Toledo, Ohio and this is my Favorite Scientific Video. I grew up playing with my Favorite Toy, a Red, Blue,Green and Yellow Large Tin Humming, Spinning Top. I am from the late 1950's and was addicted to the SOUND of the TIN TOP after I pushed the handle up and down to pump up the speed. The SPEED, SPINNING and SOUND was a HUMMING that actually SINGS a SONG at a VERY HIGH SPEED and maintains that HIGH FREQUENCY for as long as I kept the handle pumped. I would listen to this at least 1 hour every day when playing on a HARDWOOD FLOOR. This is a soothing sound to me and caused me to FEEL EUPHORIA. I know it stimulated my brain and I felt pleasure from this HIGH PITCHED HUMMING. I had a lot of scientific toys, but this was by far THE BEST TOY I EVER OWNED. MY TIN TOP THAT SANG.

Sorry for being late to the party, but the bamboo whistling spinning tops was a traditional toy in my country (dad has it when he was a kid so 1950s) and the design is quite simple. Pick a bamboo that's hollow inside and make a rectangle hole and that's it. The sound is humming and loud as it is so it's a fun toy to play with. Great job for making it with 3D printer!
Man, you should download an audio spectrograph so you can see what the heck you are hearing. There's one for android called spectroid and it works well, i think
Lovely investigative experiment! Helmholtz resonance is formed by two mechanisms 1) The air in the neck (like neck of a bottle) which acts as a mass. 2) Air in the chamber (like body of a bottle) which acts as a spring. When air moves over the mouth of such a resonator (like blowing over a bottle) the mass in the neck is excited and bounces at a specific speed on the air spring in the chamber. Just like va pendulum it operates at a very defined timing (pitch / frequency). You can control the pitch (frequency) of the whistle by adjusting the chamber volume as well as the neck length and diameter. As I mentioned, the system resonates at specific speed / pitch and multiples of that. This is why you heard two distinct tones as the top slowed down, and they appeared to be an octave (1/2 pitch) apart. I recommend designing a top with a straight narrow neck (not filleted) opening to a large chamber abruptly. You might even try a ridge on the outside of the top to cause turbulence over the opening. Feel free to get in touch if you want some in depth discussion on acoustics Angus.
Plus, turbine sirens (the kind people think of when they hear the term "air raid siren") often use two turbines tuned slightly differently to get that dissonant, startling "find shelter NOW" sound that everyone recognizes. In fact, I wonder if one could make a whistling top with two differently-sized inlets to get that effect. With the proper tuning, you could even play chords :D
I had a whistling toy top in the 80s. I found it on eBay a few years ago and it broke after a few uses because it became brittle. Only the top of the top broke so the launching mech has broken but the whistle is intact. It is not the reed type and I think it had two tones as it spun down and had a much richer mid tone than the ones you made. It’s clear plastic so I'll take some photos of it and send it to you.
"Cannot force air" challenge accepted! ;) Use a double spinner system. 1 heavy spinning disk powering a small turbine, then the spinning top as well...
The first thing I thought when seeing your cross sections was "where is the air inlet?" If you are going to use centripetal force to force the air out and thus make a whistling noise, you need some kind of hole on the top to let air in. Old-fashioned air raid horns work that way too and they are really loud. I think your tin top works in a similar way as I saw that the screw knob doesn't fall in entirely and might function as an air inlet. Anyway, just my 2 cents.
for cartoons what they actually use is called a shepard tone, which has an auditory illusion that its always getting deeper/higher when infact its just repeating over and over again
Really nice! I love to see other people getting obsessed with technical things like that! Good work, 4,99 is a fair price for all the work you put in your projects!
As I understand it, cold war air raid sirens worked on a similar principle, but instead of one hollow chamber, they used an impeller shape. They would also have two impellers tuned slightly differently to get that signature sound. It would be really interesting to see that design applied here, and make a top that sounds like an air raid siren.
A simple flat dress shoe shoestring works well in place of the nylon cord. The string end fits into the hole and the flat part lets you wind more string on the spool, so it spins faster.
I'm still pretty confident that TH-cam would algorithmically lose its mind over a video titled "RED-HOT NICKEL FIDGET SPINNER SCREAMING AT OVER 1,000°."
Just a small detail, a Tritone is something different in the context of music. What the vintage top plays is a Triad, where as the Tritone is actually a dissonant interval of two notes! For example C and F#
Add a "pea" for a warbling tone. The "pea" (used to be a dried pea in older whistles) is a small bead that's marginally larger than the sound producing vents. You may also try having several parallel holes, like a pan pipe, or even a specific assortment of holes to produce differing tones. Perhaps even placing thin tympani or drum-like caps over a portion of the surface to act as a resonance projector (similar to the thin cone-shaped part of a speaker, but flat & flush with the top surface).
I've done some research into designing an ocarina tool 3D print so I was looking into how whistles work. There are lots of videos of people making them out of clay but there doesn't seem to be any rhyme or reason to where the holes go and the actual whistle hole is not really described well in them. The ocarina has a similar resonance chamber inside.
If you played a brass or wind instrument, you have know instinctively that blowing harder (so of course more air moving through) just makes it louder! Gotta change embouchure or the length/shape of the airway to change pitch, but that Helmholtz resonance dealie is pretty neat. ps- now print a giant one! :D Thanks for supplying all the files for people to tweak!
Your tin humming top toy may be different than mine, but as far as I know, those toys don't actually use Helmholtz resonance. In the base of the top, there should be some metal reeds. These make the tone. As for the airflow, it's rather interesting. On mine for instance, if you plug up all the holes on the top perimeter of the top except one and blow into it, nothing will happen. But if you suck air out of the hole, the reed begins to make sound. The holes form a rudimentary centrifugal blower. Edit: Man. I should watch the whole video before commenting.... Literally 2 seconds after I hit play, he points out the reeds....
7:55 these aren't actually two tones. The 'mute' part is probably the natural frequency of the cavity. Physicsgirl did a video on this, but for tubes instead of spinning tops. This is an incredibly interesting discovery if you ask me
Well, you've got me hooked now. I created my own spinner from scratch (3 versions so far, actually) and I can't get it to whistle. It spins great, just no sound. I feel so lame realizing that "primitives" created perfect spinners from gourds, and I'm struggling with all my modern tech. Oh well, back to the drawing board....
It's quite logic the tone doesn't change when decreasing in velocity. If you blow harder on a flute, it's not like the tone will be higher or lower, it'll just be louder.
if you connect the external channel with a hole near the center then the spin top will act as a centrifugal pump and you can force air exiting at the sides, however as a pump surely it will reduce the spinning time a bit, hopefully not much, but will allow you to use the air flow to create sound.
I was expecting a much different sound from that tin top when you called it a tritone sound. That means something much different than "3 tones" in music.
You could try the whistle sound before spinning it, you could print it twice and attach one as the prototype to a drill and there you can test the whistle sound and speeds.
If you steal the ball out of the tip of a ball-point pen, you can super glue it to the base of your top and probably increase your spin times :) That ball in an ink pen is actually made of tungsten carbide, incredibly hard, and would make a great tip/spin point for your tops. The hardness allows for less friction loss, which means longer spin times :)
If you want to experiment with whisling shapes without wasting time and resources, one can probably make a jig with a chuck similar to a drill but with a brushless quad copter motor to spin these and also make inner side whistling parts interchangeable via sliding in and out of the round shape frame.
that duck top brought back memories i didnt know i had lmao. I used to have one of those when I was a little kid, idk if it made a sound, but it spun with the same mechanism.
They work on the same principle all he would have to do is run two of them of different sizes at the same time. Then it's just about finding the sizes that matches the tones of an air raid warning system.
I would think you could use two bearings in the launcher so to reduce wear but also reduce the possible friction created for slow down. Basically the launcher pieces would spin while launching.
Screaming spinning tops. An excellent example of a "Multiple Discovery". The idea that once it has been discovered/invented once, it will inevitably be discovered/invented elsewhere. Also an excellent example of a "Revenge Gift" to give to anyone with children. Especially if you where to replace the wear-sensitive parts like the launcher rings with something sturdier like metal rings and the rod by a by say a bamboo stick....
GamingWithFun15 I do too, it reminds me when I was a kid and played with one, I loved the thing and would play with it for hours, now watching this video, I miss having one and may have to buy one to have a part of my childhood again
If you include a small recess in the spinning point, you may be able to snap in a small ball bearing to decrease friction and wear. I imagine you might get a spin with longer duration.
I'm not surprised by the multiple frequencies of the helmholtz top. Blow gently across the top of a glass beverage bottle (ideally something like a beer bottle), then blow significantly harder. You'll notice a new resonant frequency.
I know you'll probably never read this, and someone already probably mentioned it, but that tin top isn't producing a "TriTone", that's a musical term for two notes at a specific interval. It's actually called "The Devil's Interval" because of the unsettling sound it creates. I think you meant "Triad" which is a 3 note chord. :D
Just a tiny (relatively unimportant) detail to correct: a tritone is a specific dissonant musical interval that is half an octave. The humming top produces three tones, but not a tritone. If it made a tritone, it might be even more haunting sounding!
Helmholtz Resonance is also how the Jerico trumpet dive sirens on the famous JU-87 stupa dive bomber (which served as inspiration for the Star Wars TIE fighter scream) generated such a demoralizing scweal. Not only those but also 20th century air raid sirens!

You should check out dog toys. Chukit makes a whistling balls with this exact same concept. So when you throw them, they make whistle for your pup to follow without looking up. I can see my dog runs before y throw the ball and is expecting to hear the sound to change his direction. Really interesting to se this old idea have a practical use to this day.

If you steal the ball out of the tip of a ball-point pen, you can super glue it to the base of your top and probably increase your spin times :) That ball in an ink pen is actually made of tungsten carbide, incredibly hard, and would make a great tip/spin point for your tops. The hardness allows for less friction loss, which means longer spin times :)
have you ever printed a hollow cone with the part fan at 100%? I was scared sh*tless when I started hearing whistling in the middle of the night

If you want to experiment with whisling shapes without wasting time and resources, one can probably make a jig with a chuck similar to a drill but with a brushless quad copter motor to spin these and also make inner side whistling parts interchangeable via sliding in and out of the round shape frame.
I used to love those metal spinning tops when I was younger
that duck top brought back memories i didnt know i had lmao. I used to have one of those when I was a little kid, idk if it made a sound, but it spun with the same mechanism.
Could you make one that works like an air raid siren? I wonder how loud it can get.
They work on the same principle all he would have to do is run two of them of different sizes at the same time. Then it's just about finding the sizes that matches the tones of an air raid warning system.
I would think you could use two bearings in the launcher so to reduce wear but also reduce the possible friction created for slow down. Basically the launcher pieces would spin while launching.
I always learn so much from your videos, this was really interesting!
Screaming spinning tops. An excellent example of a "Multiple Discovery". The idea that once it has been discovered/invented once, it will inevitably be discovered/invented elsewhere. Also an excellent example of a "Revenge Gift" to give to anyone with children. Especially if you where to replace the wear-sensitive parts like the launcher rings with something sturdier like metal rings and the rod by a by say a bamboo stick....
Wait seriously? That's a vintage spinning top from the 50s? I've got one of those and my little sister has the over. That's crazy.
4:38 only music people know that that is a Perfect 5th between F and C
I love this part
GamingWithFun15 I do too, it reminds me when I was a kid and played with one, I loved the thing and would play with it for hours, now watching this video, I miss having one and may have to buy one to have a part of my childhood again
That start sounded like one of those horror movie ambient sounds.
I worship your nerdiness.
This is so good! "THANKS DAAAD" :D
If you include a small recess in the spinning point, you may be able to snap in a small ball bearing to decrease friction and wear. I imagine you might get a spin with longer duration.
Nobody:
Tormented souls of the damned: ahhhhhhhhhhh!
Sweet, sweet souls..
I'm not surprised by the multiple frequencies of the helmholtz top. Blow gently across the top of a glass beverage bottle (ideally something like a beer bottle), then blow significantly harder. You'll notice a new resonant frequency.
U should really look at video abt air raid sirens by what’s inside?..... do colab if possible and design more .... 🤘🏼
2:52 it’s just overtones caused by the vibration of the top or the whistling of a different hole harmonizing with the note of another hole
Now make one that actually screams, like the Aztecs did, you know you want to
How many native Indian burial grounds would that cost?
I know you'll probably never read this, and someone already probably mentioned it, but that tin top isn't producing a "TriTone", that's a musical term for two notes at a specific interval. It's actually called "The Devil's Interval" because of the unsettling sound it creates.
I think you meant "Triad" which is a 3 note chord. :D
LOL U NEVER GON WIN WITH HOMEMADE BEYBLADES LIKE THIS
you will scare your opponent to death
counts as a win
duncan used to make a wistling wooden yoyo back in the day. i still love to play with my dads.
*Tinnitus Intensifies*
Just a tiny (relatively unimportant) detail to correct: a tritone is a specific dissonant musical interval that is half an octave. The humming top produces three tones, but not a tritone. If it made a tritone, it might be even more haunting sounding!
Note: the spinner was a paid actor
At 7:35 it makes that sound that an enderman from Minecraft does when you look into its eyes
When he said 'tritone hum' I was gearing up for a eerie tritone, not 3 pitches at the same time.
Anna Bernegger same.
Again a video that inspired me. However I don’t have energy to explore many of your designs/ projects
Am I the only one who when he spun it in the tote lid thought “hay I did the with beyblades when I was a kid”
Great video. *_Cool project._*
Me: reads/ screaming top /uhmmm
Also Me: MuSt Be PoSsEsSeD By A GhOsT!!
Helmholtz Resonance is also how the Jerico trumpet dive sirens on the famous JU-87 stupa dive bomber (which served as inspiration for the Star Wars TIE fighter scream) generated such a demoralizing scweal. Not only those but also 20th century air raid sirens!
Spinnig it out
At the speed of sound
GONNA rip it up
Nother bet IS DOWN
WERE THE TEAM with the BANG
OUR GANG is the one that's gonna win
Lets beyblade
Beyblade
Lets --beyblade
Lets --beyblade
Beyblade let it rip
This was epic, I'd never seen your videos but now I'm a subscriber.
I want one, it will be my weapon of mass...
ANNOYANCE!!!!!!!!
It is undefeatable! Lol, I want one too!
Use wet fingers on the nylon rope.. 🤦♂️how did I not think of that before? Really cool deep dive into the history. History is fascinating!.. even though I hated it in school. Hope to see more content like this. Having all the weight on the outside of the part makes it more stable.
No one:
Literally zero people:
Absolutely nothing:
A top: REEEEEEE
This is very interesting please try adding more holes and holes on the top
Imagine putting this in bayblades
That can be a good gimmick for the next beyblade series
Jayson Anderson it's not gonna happen, trust me
3 2 1 let it rip!
OH HOLY CRAP WHAT IS HAPPENING
I love the dalek shirt you’re wearing
Dude, put one upside down on a bldc motor! :D
Why bldc?
You should check out dog toys. Chukit makes a whistling balls with this exact same concept. So when you throw them, they make whistle for your pup to follow without looking up. I can see my dog runs before y throw the ball and is expecting to hear the sound to change his direction. Really interesting to se this old idea have a practical use to this day.
