Dan is still unable to enter the US to film slow mos with me. Latest reports seem to show the deepest part of his underground tunnel is directly south of Iceland. - Gav
Hi Gav! I actually used this instrument many times before. I'm working in a biochemistry lab and I used a very similar sonicator to extract proteins from bacteria cells. With this instrument, if you use it corectly, you can extract proteins that are not harmed from the forces and heat of the sonicator than you can later test their activity in a tube, purified from bacteria. It's very interesting to see this in slow mo. I didn't realize that the thin arm goes up and down. I thought that it goes slightly side-to-side. I hope you used sound-proof headphones because the sonicator can hurt you hearing. Thank you!
He entirely missed the fact that Sonicators are also called "Cell Disruptors." Apparently used by the Romulan military in OST, but Roddenberry didn't point out that a weaponized Cell Disruptor turns your tissues into liquid
I would personally love to see an experiment using one of these for underwater Morse code! I wonder if you could program one to vibrate in such a way that it would sound like a normal voice
this is commonly used in surgery.. the side of the instrument is used to cut and coagulate tissue. the cavitation effect is actually useful to increase distance between tissues.. it's like blowing bubbles into the tissue (comercial names - Sonicbeat, Thunderbeat, Harmonic scalpel)
Yes, the ophthalmologists use it - the phaco emulsifier - to liquify the cataract and flush it out before the insertion of the new lens. The neurosurgeons use a similar device to resect brain tumors - a cavitronic scalpel - with less bleeding.
Why is Donald Trump pretty and I am not? But why does he only have a wife but I have TWO HOT GIRLFRIENDS who I show off in my masterpiece YT videos? Do you know the answer, dear ta
6:54 if you look close, you can see a droplet simply trapped on the probe end. It can't get enough punch from the probe to escape, and just stays vacuum-trapped on it.
I've used these to shred open bacterial cells! They can also come with attachments to replace the probe with a small container to hold liquids. Similarly, it may be cool to do slow mo on ultrasonic cleaners used for jewelry and surgical tools.
Considering what it does to everything else...probably pretty well! That being said, I've never used it for that purpose. If nothing else though, the heat it can generate after prolonged use should do some real damage! With bacteria, we frequently keep them in an ice bath to prevent the heat from destroying the proteins we are trying to extract.
@thisoldtony turned one into an ultrasonic knife once. I think someone else did too, maybe justin from @thoughtemporium. That lets it cut through stuff
I actually had one of those ultrasonic humidifiers he mentioned when I was a kid - well, my dad did, but he used it to humidify my room. Being a curious 12-year-old, I once reached in and put my finger on the vibrating plate to see what it felt like and it was crazy unpleasant. It felt like a mix of being burned and electrified at the same time and gave my finger a really painful tingling sensation for a few minutes. After watching this, I can understand why!
I tried putting my finger in the focal point, where the water turns to vapour. It hurts, like the water in your finger is being vaporised! Well, it is!
ATTENTION! This is very unhealthy. the ultrasound can detach the periosteum. The bone is no longer supplied with blood and slowly dies. Very unhealthy !
I think that would be a cool series. Do it with a whole bunch of different tools, and types of tools. Saws, drills, lathes, reciprocating saws, jig saws, circular saws, band saws, different drill and lathe bits. Different materials (wood, metal, plastic). Man, the possibilities are endless, and I want to see them all.
For anyone who is interested: the speed of the tip in the up and down movement is on average about 12 m/s or about 43 kmph according to my own calculations. At 4:50 Gav shows that the width of the tip is 3mm. At 6:46 I took a screenshot with fullscreen and measured in paint that the width of the tip is 345 pixels. Then I compared the frame where the tip is all the way down to the frame where the tip is all the way up and I measured that it has a difference of about 24 pixels. 24 pixels equal about 0,208695652 mm which is the amount the tip moves up (and which logically is also the amount the tip moves down). Then, if you convert that length to meters and multiply it by 2 since it goes up and down in 0,000035 seconds, you get: (0,000208695652*2)/0,000035 = 11,9254658 m/s or 42,93167698 kmph Or about 12 m/s or 43 kmph
I love the timelessness of slow motion... An infinitesimally finite portion of a moment caught on film... within a single frame, finite becoming at the outer edges of the frame, yet showing, while in motion, the infinite amount of detail therein...🤔
@@billionarrow3442 HI, I'M THE THE NEIGHBOUR FROM ACROSS THE STREET. COULD YOU GUYS QUIET IT DOWN A BIT, SOME OF US ARE TRYING TO MOW THE LAWN IN PEACE.
Me, early in the video: "Hmm, what would it be like to touch the end while it's on...?" Me, later in the video: "Hmm, probably a good thing I don't have one of these."
I touched one of those that was in a water fountain, it pushed the water up and made a mist. It felt like getting electrocuted.. Didnt realise what it was before i watched this video.. But i bet that one wasnt as powerful as this one.
@@christianlind919 i mean youre not wrong, since theres so much friction it felt like youre getting shocked. But electricity also produces heat, so it kinda makes sense. However as long as you are touching the water and not the ultrasonic plate itself its safe enough to dip your finger in
In the Lab, we also use it to disintegrate cells without destroying the contents (for protein purification etc.) - it creates crazy shear forces (and crazy heat). I just realised how weird it is that we use things on a daily basis without really “seeing” how it works. Really interesting to see this, thanks! :) Will think of that video next time I use it. :D (Be careful with your ears though, can be quite unhealthy without protection)
Are these also known as "rat homogenizers?" I remember seeing rat homogenizers long ago while thumbing through science catalogs. Maybe marketing decided it wasn't an appealing name?
@@BruceDuncan You keep the sample on ice and use the sonicator only for a few seconds each time so that it doesn’t heat up too much. If you keep it on for too long, they could absolutely denature.
centrifuges have to be balanced to the nearest milligram + they are tightly closed under pressure so I doubt there is a way to find a cheap "open" centrifuge
About 20 years ago I was studied ultrosund and its practical use at the university. And of course there was no possibility to observe ultrasonic oscillations just like that. Spectacular! At last I can see the science by my own eyes.
I think it would be really cool if you were able to find a clear centrifuge which is used to seperate blood but you can seperate any mixed liquid you desire which would be wayy cool
Technically yes, but he's not super durable. He just heals fast. He can still hit hard but it's nothing compared to what it could be if his bones and armor were metal.
@@jcdenton4534 I think what he’s saying is that the Flash wouldn’t have to punch hard due to the frequency of his punches being so high. At the speeds the Flash is capable of moving in, even a small tap would be enough to cause damage equivalent to a small explosion. It’s similar to the “needle hitting the earth at the speed of light” debate, his inertia would negate his necessity for strength
In microbiology we use sonicators to sterilise difficult to clean glassware and other equipment that can't be heat-sterilised/autoclaved. The one we have though is a bath you fill with water then submerge the equipment in. Very interesting to see it in action.
I touched the disk in one of those ultrasonic diffusers and it felt like something scratched my bone was one of the worst pains ever do not recommend haha
@@my1little2pony lmao I was just about to comment about touching the disk in one of those diffusers as well. I guess we're a little more curious than bright eh? :D For me it just felt like it was boiling hot, even kind of like an electric shock but I only felt it for an instant before pulling away.
Incredible to see at 6:10 microdroplets overcome inertia thanks to simple surface tension. The square or cube law allows surface tension to be immensely stronger than G forces. One could even calculate the resistance of surface tension against acceleration within these micrometer-sized droplets. Actually wondering if this has ever been studied...
For anyone wondering what those are used for apart from mixing oil and water: they can break open cell walls to release dna or proteins in biology labs. If you want the details check out The Thought Emporium.
ownzone 817, I believe a hydraulic press channel tried crushing them, and their slo-mo showed that the explosion still started at the tail and worked its way up.
I noticed that too. He tried to clean up and look presentable for the video, but he ended up with beard hair all over his shirt. That's definitely a f**k face
Other lab equipment: How about a centrifuge? After mixing stuff, lets see how stuff seperates... ;-) Might be difficult to film, though... maybe sync the framerate to the rotation so it looks like the thing is standing still?
Woooow. I have been working in a factory with this ultrasound technology for 20 years. We use this to fuse several layers of fleece together. I know how these parts move. But I've never seen it like that before. This was amazing, Thank You
Really depends on how you define mix. Colloids aren't true mixtures by the scientific definition, but are important to biology. Also, everything is at least a tiny bit soluble in everything else. (Even if it is so small it is isn't enough to talk about.)

@@Luka11223 I'm assuming travel restrictions due to covid. Also, while I don't know to what extent, I believe Dan serves in a military fashion. Again, I don't know which military, but maybe that had something to due with it. Gav mentions why Dan isn't around much lately in one of the videos before this one, but it's been too long for me to remember what the reason was. Alls I know they're good friends that have incredible chemistry on camera, and these vids just aren't the same without Dan around
@@stephanratliff true we need one more person to be in the video for some jokes or some fun facts.. what i cant say is that they have that incredible chemistry, sometimes they just trying to force it its like all those years they didnt find each other :)) i like both of em but i honestly think someone else would be better. Mythbusters had that chemistry you talking. or maybe its just me :)
Used sonicators are also called "cell disruptors." Note that old dead parts-units are often easy to repair, because if the user had twisted the wrong part while trying to replace the "horn," it tears the internal wires right off the big piezo transducer. Fun fact: we make "nebulizers" with Lithium Niobate plates driven at 100MHz. Apparently the particle-size is proportional to acoustic wavelength, because at 100MHz, the fog droplets are only few microns, and invisible without a microscope. (Used to load proteins into mass spectrometers, alternative to Electrospray sample-heads.)
Love the description "When it really comes down to it, in this video Gav is filming a vibrating stick in slow mo. However, not all sticks vibrate. Especially not as fast as this one. "
I setup 20-40khz ultrasonic welders about 1meter tall and and several KW amps. Welding Colored Clear plastic on security seals took about 3-600ms. Tamper proof welds were beautiful. Low Maintenance, but quite timely to setup.
I want to see electroboom's high voltage spark generator that he made in one of his latest videos! The way he explained it the spark first jumps across multiple open air "switches" before making a large arc. Seems really cool to film in super slowmo.
@@justinmiller129 It wouldn't surprise me if you were a bot... But in the off chance you're not. My comment in combination with a slowmo guys video on a sonicator reminds you of a video where some guy feeds a store bought chicken to a mountain lion? How in thell?
Fun fact? Fun??? FUN, you say? O_O That sounds absolutely terrifying. 'And, on a lighter note, we also use ultrasonic wave generation on a massive scale to displace the actual ethereal membrane between other-dimensional plains and our current reality. It's fun.' :D
I've put my finger in my 100w ultrasonic cleaner, it feels like pins and needles. Besides the immediate physical damage, I wonder how much of the underlying skin, capillaries, and muscle could be killed by this tool.
Dan is still unable to enter the US to film slow mos with me. Latest reports seem to show the deepest part of his underground tunnel is directly south of Iceland. - Gav
I used to use a piece of lab equipment called a flow cytometer, which would count microscopic particles in a sample by creating a very thin stream of water, and photographing individual droplets. A part of the machine was a form of sonicator that would send sound waves through the stream so that you could control the size of the droplets perfectly and time them so the computer could photograph them as they passed the camera. see if you can get your hands on one of those, there was a microscopic camera built in for calibration but it wasn't fast enough to visualise the change from a stream to droplets
Gavin: 'It is a piece of professional scientific equipment used to mix liquids that are hard to mix normally.' Gavin 5 minutes later: 'You can use it as a fire starter!!! :D'
Alright! Hear me out. You guys once filmed the speed of light.. So, in theory, if you film something ridiculously fast in front of a mirror, you should be able to capture the delay of the reflection! That would be so awesome, I'd love to see that.
Check out the film “visualising video at the speed of light”, from MIT. That was pretty cool. And to make it they had to know the exact speed of light for superposing the results.

For anyone who is interested: the speed of the tip in the up and down movement is on average about 12 m/s or about 43 kmph according to my own calculations.
At 4:50 Gav shows that the width of the tip is 3mm.

Then I compared the frame where the tip is all the way down to the frame where the tip is all the way up and I measured that it has a difference of about 24 pixels.
24 pixels equal about 0,208695652 mm which is the amount the tip moves up (and which logically is also the amount the tip moves down).
Then, if you convert that length to meters and multiply it by 2 since it goes up and down in 0,000035 seconds, you get:
(0,000208695652*2)/0,000035 = 11,9254658 m/s or 42,93167698 kmph
Or about 12 m/s or 43 kmph

Incredible to see at 6:10 microdroplets overcome inertia thanks to simple surface tension. The square or cube law allows surface tension to be immensely stronger than G forces. One could even calculate the resistance of surface tension against acceleration within these micrometer-sized droplets. Actually wondering if this has ever been studied...
Do a titration, I'd love to see the moment a solution switches to an indicated colour in slow-motion
For anyone wondering what those are used for apart from mixing oil and water: they can break open cell walls to release dna or proteins in biology labs. If you want the details check out The Thought Emporium.
I want one to make mayonese.
@Frullie lmao
Ultrasonic obliterator VS Prince rupert's drop!!!
This is very interesting question 🤔
Yes someone needs to do this
It will probably destroy it very quickly by sending vibrations down the tail and snapping it.
@@evilsharkey8954 are you sure about that?
Yessss!!!!
ownzone 817, I believe a hydraulic press channel tried crushing them, and their slo-mo showed that the explosion still started at the tail and worked its way up.
Seems like a great anniversary gift
Looks like teenage Gavin is making a comeback.
Looks like Gavin's shaved onto his shirt xD either that or an oddly designed shirt
Or he's worn it so much it is growing a beard itself.
I noticed that too. He tried to clean up and look presentable for the video, but he ended up with beard hair all over his shirt. That's definitely a f**k face
Think his chest hair is eating through his t-shirt
Looks more like he's got body hair so thick and luxurious that he can comb and braid it.
@@Nefoedd I reckon that’s the case mate 😂
Other lab equipment: How about a centrifuge? After mixing stuff, lets see how stuff seperates... ;-) Might be difficult to film, though... maybe sync the framerate to the rotation so it looks like the thing is standing still?
that would be pretty cool, if it looked like it was stationary but the contents were mixing
Definitely try a centrifuge! Make sure to load only one side of it for the grand finale 🤯
Woooow. I have been working in a factory with this ultrasound technology for 20 years. We use this to fuse several layers of fleece together. I know how these parts move. But I've never seen it like that before. This was amazing, Thank You
My highschool teacher: "Water and oil don't mix."
Gav: "You are just not mixing fast enough, duh."
Behold: Milk!

Emulsification is a thing.
Really depends on how you define mix. Colloids aren't true mixtures by the scientific definition, but are important to biology. Also, everything is at least a tiny bit soluble in everything else. (Even if it is so small it is isn't enough to talk about.)
Can we talk about how cool the name "ultrasonic obliterater" is!
The Omnissiah, approves.
The only other cooler name I've heard was Infant Nebulizer
Sounds like a weapon from gundam ngl >w
Ya miss him, Don't ya Gav? It's ok. We miss him too. You should capture the reunion and the inevitable bro hug with you guys jumping into each other's arms in slowmo. It'll be nice to see you two working together again hopefully soon
What even happened
@@Luka11223 I'm assuming travel restrictions due to covid. Also, while I don't know to what extent, I believe Dan serves in a military fashion. Again, I don't know which military, but maybe that had something to due with it. Gav mentions why Dan isn't around much lately in one of the videos before this one, but it's been too long for me to remember what the reason was. Alls I know they're good friends that have incredible chemistry on camera, and these vids just aren't the same without Dan around
@@stephanratliff thank you sir
@@stephanratliff true we need one more person to be in the video for some jokes or some fun facts.. what i cant say is that they have that incredible chemistry, sometimes they just trying to force it its like all those years they didnt find each other :)) i like both of em but i honestly think someone else would be better. Mythbusters had that chemistry you talking. or maybe its just me :)
8:00 Never thought I'd see motionblur in slowmotion

what about a centrifuge? seeing how it separates things could be interesting in slowmo
How would he be able to mount the (very expensive) phantom to something spinning at several thousand rpm?
Gavin's chest is so hairy his shirt grows hair on its chest.
Imagine how quickly you could make angel delight with that thing!

Hi internet, me too!
Years of practice, boys.
haven't you heard?
"This thing's a fire hazard!"
*proceeds to use on labcoat*
Gav is the long-haired supermodel the world needs 😎😂
We can tell he shaved just before the video, still a lot of hair Gav.
He realllly needs a good cut
Gav lookin' like he does nowadays is just of the things that no one knew that we needed before we got it XD
He is also really messy
Don't change a thing!
Used sonicators are also called "cell disruptors." Note that old dead parts-units are often easy to repair, because if the user had twisted the wrong part while trying to replace the "horn," it tears the internal wires right off the big piezo transducer.
Fun fact: we make "nebulizers" with Lithium Niobate plates driven at 100MHz. Apparently the particle-size is proportional to acoustic wavelength, because at 100MHz, the fog droplets are only few microns, and invisible without a microscope. (Used to load proteins into mass spectrometers, alternative to Electrospray sample-heads.)
Love the description
"When it really comes down to it, in this video Gav is filming a vibrating stick in slow mo. However, not all sticks vibrate. Especially not as fast as this one. "
Gavin: "This thing's a fire hazard!"
Also Gavin: *proceeds to use fire hazard on clothing he is wearing*
I was literally thinking of posting the exact same comment
The beard is a fire hazard.
Safety first - his lab coat is made of pure, super safe, asbestos
🤣🤣🤣🤣🤣🤣🤣🤣🤣
This quarantine really did a number on him, didn't it?
Oof that water droplet “don’t feel so good Mr. Stark”
I setup 20-40khz ultrasonic welders about 1meter tall and and several KW amps. Welding Colored Clear plastic on security seals took about 3-600ms. Tamper proof welds were beautiful. Low Maintenance, but quite timely to setup.
I want to see electroboom's high voltage spark generator that he made in one of his latest videos! The way he explained it the spark first jumps across multiple open air "switches" before making a large arc. Seems really cool to film in super slowmo.
That *_sonicator_* reminds me of this video th-cam.com/video/U2rNnzVotS0/w-d-xo.html&qaz
@@justinmiller129 It wouldn't surprise me if you were a bot... But in the off chance you're not. My comment in combination with a slowmo guys video on a sonicator reminds you of a video where some guy feeds a store bought chicken to a mountain lion? How in thell?
Fun fact: We also use them to sheer down DNA into smaller pieces.
DNA just isn't small enough eh? No pleasing these scientists.
And to rip cell membranes apart to get at intracellular components.
Fun fact? Fun??? FUN, you say? O_O That sounds absolutely terrifying.
'And, on a lighter note, we also use ultrasonic wave generation on a massive scale to displace the actual ethereal membrane between other-dimensional plains and our current reality. It's fun.' :D
so what would it do to human skin?
@@spammyjenkins87 I would imagine, cook its way through it like a tiny lightsaber with little to no resistance.
Sounds like you've seen the technology connections video on humidifiers
That was very cool!
Basically breaking things down. The fibers in the cloth, so cool.
Last time I was this early Gavin had short hair.
I do not also

Well, looks like he had a trim recently from the state of his shirt!
@@AlFooteIII Probably just the chest hair :)
(more likely just a small beard trim though to be realistic)
I've been wondering how water jet cuts thick metal in slow mo, i think its gonna be super fun to watch
There's sand in the water
Hard to see anything through water splashes around the cut :(
My brain: touch it while it’s running it might be cool
Ahem
WHaT
I've put my finger in my 100w ultrasonic cleaner, it feels like pins and needles. Besides the immediate physical damage, I wonder how much of the underlying skin, capillaries, and muscle could be killed by this tool.

"Welcome to the... Slow Mo Guy" well now I'm sad...
How does he decide where his chest hair starts when shaving
That's his secret, cap. He never shaves
You read my thoughts! 🤣
Dan is still unable to enter the US to film slow mos with me. Latest reports seem to show the deepest part of his underground tunnel is directly south of Iceland. - Gav
5:12 Now that is an awesome capture. That micro millimetre droplet gets smashed into gas/mist/steam.
Gas/vapor
Mist/steam
I used to use a piece of lab equipment called a flow cytometer, which would count microscopic particles in a sample by creating a very thin stream of water, and photographing individual droplets. A part of the machine was a form of sonicator that would send sound waves through the stream so that you could control the size of the droplets perfectly and time them so the computer could photograph them as they passed the camera.
see if you can get your hands on one of those, there was a microscopic camera built in for calibration but it wasn't fast enough to visualise the change from a stream to droplets
I seriously miss videos with both of you.
Gavin: 'It is a piece of professional scientific equipment used to mix liquids that are hard to mix normally.'
Gavin 5 minutes later: 'You can use it as a fire starter!!! :D'

"YOU SHALL MIX!". Best tasting oil/vinegar dressings I've ever had were mixed ultrasonically ...
Never separated either.

He didnt mix them
Your science teacher is still right. But now you have no teeth.
*hold my phantom..edit it
@@Trathien- but he did, he just mixed it into an unstable emulsion that started to break as soon as the device was turned off
Technically you can mix them if you have an emulsifier
BEWARE CAT OWNERS: My cat did NOT like the noise. So make sure they aren't on your lap like mine was... ouch

You must have some amazing speakers; poor cat, that was likely rather painful.
or just use a headset
Alright! Hear me out. You guys once filmed the speed of light.. So, in theory, if you film something ridiculously fast in front of a mirror, you should be able to capture the delay of the reflection! That would be so awesome, I'd love to see that.
even using this Obliterator every cycle the light can go 10,000 m
so it's very hard to find such macroscopic thing which can move in 1 trillion fbs
Check out the film “visualising video at the speed of light”, from MIT. That was pretty cool. And to make it they had to know the exact speed of light for superposing the results.
That’s actually a really good idea
No
