3D Printed Screaming Spinning Tops 

"How does something so small, make so much sound for so long?" - Angus doesn't have kids.

What it really sounds like : *whirring How I thought it sounds like : *AAAAAAAAAAAAAAAAHHHHHHH*

Can you make a top that sounds like a air raid siren

This is so complicated, jeez. Just buy a super cheap one then bind a tortured human soul to it.

Give a fish to a man and he'll eat one time, give a fish to an engineer and he will replicate the fish and print a ton of them until they swim

Holy shit, that whistle mechanism thing can be good gimmick for beyblades

4:34 "tritone hum? Why would they choose such a horrible interval?" *Hears the chord* "ohhh, triad. He meant triad."

Look at this dude showing off that he has a dad.

so small, so loud for so long... an apt description of most children!!

0:01 when you look at an enderman

congratulations you just triggered a vietnam flashback

Everyone: makes 10:01 min vid for ad revenue Maker Muse: makes 9:30 min vid to spare us of the ads.

You should do a follow up video using other people's submitted designs!

"How does something so small, make so much sound, for so long?" Me: *slowly looks to my chihuahua*

Now, make a screaming Beyblade, and market it to the manufacturers. Kids will love it, parents will hate it.

"Cannot force air" challenge accepted! ;) Use a double spinner system. 1 heavy spinning disk powering a small turbine, then the spinning top as well...

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. THE SECOND BEST TOY WAS MY TRAIN SET THAT CONVERTED WATER INTO STEAM AND THE BLOWING WHISTLE COMBINED WITH STEAM STREAMING OUT OF THE WHISTLE. Vanessa Golston, October 27, 2019 Happy Sunday 2:16AM

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

So a screaming beyblade? "LET IT *REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE* "

Some tornado and bombing sirens are a spinning thing, wonder if using that design might be louder.

I am just imagining a spinning top just screaming “FRICK FRICK FRICK FRICK FRICK FRICK FRICKkKkkKkKK”

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.

RU-vid pranksters: *Taking screaming tops to retirement homes and watching Vietnam war survivors eyes widen with flashbacks social experiment!*

Now you just have to make a screaming fidget spinner and RU-vid will be yours for the taking.

Imagine if a referee uses this in a game. Opponent: "gets a point" Referee: let it rip!!!

Don't tops spin backwards in australia like toilet flushes?

Your final one sounds like the cartoon falling or bomb drop

For added nerd-credit you could add an led strip for roto-writing!

Kind of want to see a 3D printed Aztec Death Whistle now.

You should try and make an advanced launcher that uses gears to amp up the velocity

*Tinnitus Intensifies*

4:38 only music people know that that is a Perfect 5th between F and C I love this part

Nobody: Tormented souls of the damned: ahhhhhhhhhhh!

You should make trompos spin tops

Can you improve the “screaming skull” whistle? Make it more “scary”. Make it louder. Make it more “ghostly”.

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.

Could you make one that works like an air raid siren? I wonder how loud it can get.

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 :)

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....

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 always learn so much from your videos, this was really interesting!

duncan used to make a wistling wooden yoyo back in the day. i still love to play with my dads.

When he said 'tritone hum' I was gearing up for a eerie tritone, not 3 pitches at the same time.

They’re called a bromtol in dutch, they work amazing

I had that exact spinning top you ordered when i was a kid.

This is very interesting please try adding more holes and holes on the top

Me: reads/ screaming top /uhmmm Also Me: MuSt Be PoSsEsSeD By A GhOsT!!

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.

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.

If these tops use Helmholtz resonance, I think that makes them actually ocarinas. Ocarinas are Helmholtz resonators as well.

Imagine rigging something up so that whenever somebody walks through a door it just drops like 50 of these at once

The science of resonating frequencies explained why the frequency doesn’t change much

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

It’s the size of the hole that make the height of the frequency larger=lower

Now make one that actually screams, like the Aztecs did, you know you want to

Helmholtz resonators won't shift pitch with air velocity. The fundamental can actually shift up or down octaves with higher or lower air velocities but the pitch will remain the same

Dear God, the kid channels in the recommend

Build a bigger top where you can put a servo inside that changes the shape of the cavity. Could be difficult to balance but worth being able to actively control and possibly program a song into it?

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

You could put bearings on the handle so when you're spinning it doesn't wear down the plastic

I want one, it will be my weapon of mass... ANNOYANCE!!!!!!!!

Have a slight raised area just after the side hole to force air in. Have exit hole on top near shaft designed like whistle.

U should really look at video abt air raid sirens by what’s inside?..... do colab if possible and design more .... 🤘🏼

Make a top with 2 separated chambers of different sizes. This should give you the dual tone you're looking for

Imagine playing this at a dark house in 12 pm *Ive seen this raw strength only once before*

You want to experience really really bass whistle sound? It's easy, just drive your car with one of the back seats's windows open (only that one, doesn't matter which side), because it's kind of a square. Then go on a straight line at a constant speed of about 40, 50 km and then all the car's inner pressure is going to have fluctuations, it's the same principle but in a car scale, so really bassy sound (probably you have experienced it before)

LOL U NEVER GON WIN WITH HOMEMADE BEYBLADES LIKE THIS

video: sound warning me: tries to cover ears also me: remembering im wearing a headset

Dude, put one upside down on a bldc motor! :D

Make three internal chambers with different sized holes to make a tri tone one. Or something along that line.

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....

Aztec death whistle tops would make some money.

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.

If you google air raid siren, you'll find the best geometries for spinning noise making things. Its a good a subject to read about.

Imagine putting this in bayblades

My Mom use to have one of those large whistling tops at my Grandparents house.

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”

i love how everybody is taking this seriously we just vibing to spinning tops

This is so good! "THANKS DAAAD" :D

you should try to put some reeds in to give it a harmonica-like sound!

i'd rather make my own then go through all that rubbish signing up!! i follow your chanel and am happy to pay for your design but why go through all that rig maroll!

I love his shirt

Great video! thanks for sharing the files to modify. Your channel is so useful!

Note: the spinner was a paid actor

Velocity is the speed of somthing moving in a straight line

That start sounded like one of those horror movie ambient sounds.

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.

I love how much his dad shows him stuff that he gets into and it inspires him. This is like the 3rd video today where I've heard him say his dad was an influence to the project he's doing. I always admire a father/son duo with that kind of relationship. That's special. His dad did a good job too because look at how smart his boy turned out to be! I wonder how proud he must feel seeing his boy engineering this stuff and running a RU-vid channel that has hugely influenced the 3D printing community.

I feel like this could be kinda like a weapon with the noise being able to distract enemy’s or something.

Some disturbing videos by youtube algorithm -------->

You: It's SO LOUD Me: You clearly edited it so it was quieter. Your voice is louder than any of the tops.

Technology in 2019: making your own screaming plastic bayblade

Build a launch using an old hard drive and see if you can get some serious revs going

4:41 my brain is creating an image of an overpowered item being found.

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!

The first clip of the failed one sounded creepy and I want the file

No one: Literally zero people: Absolutely nothing: A top: REEEEEEE

The last one sounds a lot like a ocarina! I wonder if they work similarly?

Hi Angus, Thanks for your video and your continued inspiration to me. I've just finished creating a video for my channel, 3DPrintingTexan to teach people how to make the top you made in DesignSpark Mechanical. Awesome video! You will be featured prominently on my channel.
