[@brianbethea3069]

@@buggsy5 I don't know. From what I saw, the bubbles mostly broke off on the low pedal tone rather than the upper melodic and harmonic lines. It would make sense to me that a lower frequency would create waves wide enough to cause bubbles to break off, and the violin is cut off from a whole octave and a half of low range that the cello has. Then again, I imagine that a smaller bubble might have the same effect with violin.

[@9SmartSand6]

You notice Don started with a sine wave, then showed a square wave and a triangle wave. 9:20 "There's something about the cello..." the cello (and other string instruments) produce a _sawtooth_ wave, which ramps up linearly, then has an abrupt decrease in amplitude. My guess would be that this sudden negative delta in pressure would facilitate the smaller droplets shearing off from the internal air/water boundary. And apparently they occur more readily at a frequency resonant with either the diameter of the internal air sphere, the diameter of the water sphere, or the thickness of the water sphere. So a sawtooth wave, swept through that frequency range should work, much like the cello music.

[@Xavier-rp2ko]

[@9SmartSand6]

[@JandJandJandJandJ]

As someone who works with music and general sound waves, I think I might know why cello makes those bubbles split off and bounce around when in zero gravity. Stringed instruments usually produce frequencies very similar in shape to sine waves when unfiltered. With instruments where you use a plectrum or pizzicato plucking such as classical guitar or banjo, these sine waves start and stop very suddenly and have a very acute attack. For cello, it still produces a sine wave sound, but since it is played with a bow, the attack is much less sharp. The slower introduction of the wave causes the water to slowly start to vibrate and bubble. His oscillator was playing harsh sine and square waves and causing the surface to vibrate right away. Thus, he didnt get the same effect. My best guess is that the slow attack of the wave accommodates the lack of coalescence, sort of pinching the droplet off as the waves become more severe. Of course, that's just an educated guess. I'd love to see it actually experimented upon.

[@DarthShadow25]

What do you mean by attack?

[@JandJandJandJandJ]

If my perfect pitch is of any use - it's noticing that the air bubble becomes distorted when the cello plays an F#2, F#3 and C#3 (or close-proximity surrounding frequencies), but not really at all when the cello plays an F#4 (noticeable at the end). With a somewhat amateur level of acoustic physics education, I understand it's something related to resonant frequencies (and harmonic series, given the octave -> fifth pattern) but if anyone could explain *exactly* what is going on here, that'd be great!

[@16willthompson65]

I posted a comment about resonate frequencies as well, its probably dependent on what the depth of the fluid is at the time of testing

[@azureorbit]

+16willthompson Yes, it *is* dependent on that. The surface of the water is an anti-node, and the speaker acts as an anti-node. You'll have to calculate based on the speed of sound and the frequency you've got it at

[@geminifourthmommy]

[@waterlubber]

9:17 The cello's waveform is a sawtooth wave, or at least very close. The bow moving across the string is coated with rosin, a sticky tree sap that helps the bow stick to the string.

My four kiddos and I just watched this and my brilliant daughter said, “When we listen to the cello, imagine what is happening in our bodies considering the fact that we drink and are made up of mostly water.” 🤯 I got goosebumps all over when she said that, such a powerful thought and totally worth scientifically researching!!! We love this video! Thanks Dustin!!!

[@darthmeowry]

I need a 10 hour loop of that cello water droplet footage. Like seriously. Amazing stuff!

[@DJignyte]

With the Cello, could it be that both spheres have differing resonant frequencies? At 9:44 the higher tone (sounds like a C sharp ~280Hz fundamental) looks to resonate with the outer sphere of water while the lower tones at 9:50 (Sounds like a C or C sharp but an octave lower ~130Hz fundamental) seem to resonate with the inner sphere of air. Thats quite interesting! I'm curious, is the volume of the outer sphere double that of the inner one? Great video, man!

[@LeiosLabs]

Wait, do you mean that the difference in resonance frequencies cause enough disturbance to eject the water bubbles into the central air pocket? I feel like we might be able to model the system as a sort of spherical resonator with surface distortion. Definitely something to look into more!

[@jg3142]

Why do droplets only break off inside? Maybe equivalently, why aren't there waves on the outer surface of the drop?

[@LeiosLabs]

jg3142 I thought this was because the music was being played in the inner bubble not the outer water. Maybe I'm wrong, though.

[@darklion8390]

A sound observation! xD I could only guess the difference in surface area of the two bubbles would also subtly diffuse the wavelength across the surface tension? Like ripples spread, perhaps? :o

Yeah, I don't think I've seen this before either, and it may actually be where we live, because certain places have different water filtration protocals, where I live, we have a heavy water filtration system, so that may affect how the H2O molecule. This specific effect may have to do with multiple variables, such as how 'hard' the water is etc., that's my closest guess as to why we haven't seen it, anyway...

7:10 - It's nothing to do with the kinetic energy of the collision but the increased surface area provided by the distorted water surface providing a larger air cushion. If it was CKE then when the wave rises to meet the drop it should burst and it doesn't in many examples you provided.

[@buckshot.bennys]

Why would an increase just of surface area in the distorted water make a difference? It's the high and low spots of the distorted water creating, well kinda like the thing they do in kindergarten where the whole class holds on to a massive blanket or quilt and they shake it up and down, and then throw a beach ball on the erratically moving blanket. The surface area isn't increasing, it's the, idk if oscillation is the right word, or the movement of that surface that cradles the beach ball. Or in this case, a drop of water.

9:24 - before I watch further: I'm a sound guy and every sound guy knows that string instruments produce waveforms most resembling a sawtooth wave.

[@ryanp2743]

I’ve never seen this happen other than on hydrophobic surfaces, never on itself...I’m so confused

[@juliancox3229]

Air gap theory does not ring true to my ear. Droplet is a low energy state. It needs energy to make it flat. Think of the “flat” surface of the water part of a global sphere. It’s two spheres that have come to rest. Most likely if you made the conditions still and cold enough and the atmosphere something with a greater vapor pressure than water vapor, you could keep a droplet there almost indefinitely. BTW the resonance patterns of musical notes in water is stunning. So much information that is so distinct for different notes it looks like unpacking a giant compression algorithm. You can see how hearing might work - well worth looking up.

[@celivalg]

I've seen it happen a lot in my shower, the floor isn't hydrophobic and when it's dry it doesn't happen, however, once a thin layer of water covers the floor, little tiny droplets starts to form on top of the water surface,I find it really pretty and always wondered why it was happening

There appears that sonoiluminence is being created at a certain frequency, but it can't be , because they shoot out and at very high speed right out of the picture. What to heck are those lights, or am I seeing things?

[@you2tooyou2too]

. I've enjoyed 'floating water' since as a child I swam in a large pond in the rain, and saw that most of the raindrops are nearly the same size and the same as the droplet that pops off the top of each rebound water spike, and jump back up to a uniform height (about 2") and each jump releases a fan of smaller droplets that skitter about, interfering/riding on the nearby wave formations. It was an enthralling light show of dancing droplets. I always suspected that the electrical properties of surface tension contributed to the 'lubrication' that inhibited the skitterers from melding immediately. . Re 9:20 The cello is mellow, ie mostly first few sine wave harmonics. These compression waves are able to form strong (focused) nodes on the negatively curved (inside) surface, strong enough to eject droplets, which then drift off with little enough speed to be unable to rejoin the sphere easily. Wish I had more physical statistics in math class, and a better understanding of how Van der Waal's force affects the surface tension. . As for the theory that it is the viscosity of air that provides the lubrication, I still think that is not enough, though I do enjoy dropping a large pane of glass onto a flat surface & relying on the viscosity of air to prevent it shattering. Fun stuff!!!

[@Ddub1083]

+J Seed Or you could just get Milkdrop 2 which has a very similar visualizer already.

[@DonSolaris]

Destin, spectrogram in this case in not crucial. I am 99% it's the shape of the wave itself, which in the case of a cello is a form of a sawtooth wave (plus harmonics). If you just look at a shape of a sawtooth it reveals a lot. For even cooler effect i would recommend synthetically generated (perfect) sawtooth. Unfortunately i don't have a lab in space to verify, but i am 99% the sawtooth at specific freq will get you in these kinds of effects that we witnessed. I am also 99% it is the specific shape of the waveform that does that, rather than it's more less fixed spectra. Cello is fixed spectra type of instrument, bcs it's a resonant body instrument. Yes you can transpose notes, but the spectra will remain similarly shaped across all range. There's so much more to talk on this subject but typing among 9854 useless comments is so futile it hurts.
