The glasses are breaking because they want to end their suffering, not because of the resonant frequency :)
Yep, thought the same. That glas just had enough being yelled at and decided to quit.
ThePotionery :
Ohh the pain, the pain.
Lost In Space - Physics l!😫😫😫
"ALRIGHT! ALRIGHT I'LL BREAK! JUST STOP YELLING AT ME *sobs* "
1000th like
Waiting for the dudes to not get the joke.
I love how at 6:57 when the glass broke off, it made a sound that is very similar in pitch to the Windows XP error sound. "Error. Glass.exe failed to maintain structural integrity. Press any key to continue."
sounded like Rose 🌹 from plant vs zombies
Lmao, I had the same thought!

It's showtime
Sends shivers down my spine
@@lilidesisto5385 cracks are breaking all the time
"don't try this at home"
me immediatly runs to get a wine glass...
Me too lol I'm gonna go to Walmart just to make a video
IM DEFINITELY GONNA DO THIS LMAO
I didn't like your comment cause you got exact 444 likes :D
did you do it???
Try it in your neighbour's home.
I used to think resonance was the most boring part of physics because I wasn't interested in breaking wine glasses, but then I learnt how important it is in everything from laser systems to astrophysics
I love your channel @Tibees why are there only little likes !
I would love to meet you once in my life !
Hi toby love ur channel
@@studyaccount4251 omg i just realized she has a phys channel !
@Edy Puentes lmfaooooooooooo
@Edy Puentes lmfao right 🤣🤣🤣 Trueeeeee
I bet getting some of that glass in your eye really hertz.
Underrated comment
@@Luke12C sounds about right
Because it did not resonate with others.
These others seem to have discordant tastes.
hehe
Best part of the video “so Diana, I’m trying to print a PDF” 😂
😂 😂 😂
literally the story of my life :') (I do tech support for a living for years now. It's the bane of my existence...)
@@AsmodeusMictian I actually do not do tech support for a living, yet it is still the bane of my existence. And please! Can they find a way to actually setup printers easily...? I mean really plug and play? Not plug and pray...
@@madjack7777 I think the best they can do is something that works for 'most' instances. There's so many variables that I'm not sure there'd be a way to have it work literally every time.
Would be AMAZING though!!!
Your neighbors must love you. lmao
Yes, my roommates were in the house while I recorded this. They kept up a conversation downstairs, and paused for me to screech, then talked during the silences. And all was normal.
Physics Girl I would love to try this, but I have hyper-sensative hearinɡ. I would be in so much pain! Your roomates must be really tollerant and patient to live with you as their roomate. XD
Indeed, they are.
Physics Girl did you watch Mike Boyd's video?
he says start from a low pitch to high pitch that would've made it easier
Having a wineglass hit with a strobe linked to the frequency of the voice or maybe using polarised light might show up the stresses that cause the fail. Love your work Diana.
Physics Girl when you say it took a long time to break the un-pre-cracked glass, how long do you mean? 5 minutes? 15 minutes? 1/2 hr? An hour? What’s a long time?
Hmmmm don’t try at home... can I try in a busy restaurant then?
Hehehe
Remember to put on googles!
Michał Wójciak Remember to put goggles on all those faces.
after 1:57, I kick stop the video and came down into the comments for this. To blah blah blah back to you Physics Girl... 😝
Don't forget your sunglasses and some high speed cameras.
6:57 That look was priceless. It was the look of "Holy crap, it worked!" That anyone who has played around with material science knows. Also, the ding sounded like a Windows 95 error. :)
"Don't try this at home. Go to a restaurant and do it."
Bartender's face when someone turns on the recording at the restaurants and all the glasses break xD
I'm just immediately reminded of the scene in Harry Potter with the Fat Lady.
Christina Paez HELL YEAH
Did someone forget the password again?
Sameeeeee
OMG RIGHT
OMG SAME!!!!!!!

Hi Dianna, I measured the frequency at 6:57 to be *649 Hz,* just as the wine glass broke (using a tuning app). It's interesting, you were singing at *652 +/- 1 Hz* from 6:47-6:55 and then dropped to about *642 Hz* up to *649 Hz.* As soon as you hit *649 Hz,* the glass broke. So maybe that is the resonant frequency
DANG JOS or...more likely it was a harmonic resonant frequency. flick the glass and see how high it rang. then see if 642 is a whole division of that
You are hard core.
This seems to support the mechanical engineer's second hypothesis
I think the condensation I could see forming from singing so close to it might affect the resonant frequency too. Adds some variation.
DANG JOS what’s the tuning app name?
omg 6:56 I've never seen one break like that
and the sound the part that fell makes while falling, is cool
(lyrics) EEEEEEEEEEEEEEEEEEEEEAH... (SILENCE)
ITS SO FUNNY AGHAHA
Me a boy in puberty with voice changes:tries to make the same sound
*walrus sounds intensifies*
OK, Google... 391.98 Hz please. Loud!
Olaf Doschke that's not working for me
It's perhaps better that way.
There was a hilarious case of a comedian ordering his own DVD in a show via Amazons Alexa. That worked in some cases!

Headphones + protection glasses + your face when the "new" glass broke = I had to pause and laugh my lungs out 😁. Great video Dianna!! 👍👏
Warrior SON : You're creepy AF!
Glen Ralph 😂😂😂
oh my god JUSTINE!!!! my favourite fashion youtuber on three comment section of my favourite physics youtuber?? i have seen everything now.
I had the same reaction 😄😄 I did wonder, if she had noise cancelling headphones on how did she know she was at the right pitch? Lol
Omggg! Justine, I love your videos. 😍
People with perfect pitch:
That’s a f not an e
lol
@twosetviolin
Good for you. Knowing notes names doesn’t make you a good singer
@@Justanothergirl0422 perfect pitch gang
bst Meg sure, but it’s super impressive
7:12 Imagine if the glass completely shattered cuz of that sound.
Wave7 lol
6:58-7:02 The amount of "holy sh*t, did this realy happen" in her face is priceless.
The only thing, which would have topped that is the joy screaming at 7:12 breaking her safety goggles.
Finishing off with a really happy expression. :) Too cute.
Our eight year old daughter is out of school because of snow. I showed her this video and she said "that was awesome!" Thanks Dianna!
Girls need more science role models, and Dianna is a terrific place to start!
I am a sixty two year old son out of college and I agree; Dianna makes physics fun. Thanks Dianna!
Wine glass: i am the only one that can do this note “aaaaa”
Physics girl: “aaaaa”
Wine glass: (getting jealous and breaks)
"Amazing! Just with my voice!"
"Fortuna Major"
😂😂
Only hp fans would get that
Happy physicsinging... ?
nope... not anymore..
Happy physicsinginginginginginginginginginging SNAP!
Dianna learns fast I can tell you! Awesome video!
Wine glass be like
wine flass: CAUSE I'M ONE STEP CLOSER TO THE EDGE, AND I'M ABOUT TO..
*shatters*
Underrated af.
ahh i miss him
You spelt glass like flass
6:57-7:13 *When you actually get a decent score on a test you didn't study for* 😂😂😂
1:58 ok... i’ll try it at a friends house
i find there's a similar effect when you sing in the bathtub or in a shower stall. in a range of notes you might find a note that will jump out and sound a LOT louder than the rest even though you're singing at a fairly constant volume. bathrooms work better because of all the harder surfaces reflecting sound more than say, wallpaper or latex paints.
also the shape of the tub
actually, it can work in pretty much every room, as long as there is no (or not much) furniture in the room. but sure, harder surfaces help for the loudness.
Fun-Fact: my speaking voice contains the resonant frequency of my sisters living room, and therefor I always have to change my voice when talking in there :D
@@i-dinen-lug This is getting into precisely the reason why recording studios are so tricky to design well.
"And if you shake something hard enough, it will eventually break"
6:57 ERROR
Why ?
@@Kim-qu6rt Microsoft sound effect
man she was so very surprised looking at the broken glass second time.....it was from 6:58-7:01.....
she won that!!!!!
Another brilliant video Dianna, one of the few channels on TH-cam that just keep improving.
i love how much collaboration you do. cool to see the youtube community hangin out and makin cool videos.
1:48 Priceless reaction ever of Physics Girl ever!
Indeed, she looks so cute and excited for her accomplishment😍 Love Physics Girl❤️
In one word: Fascillating
As a technology librarian, I fully appreciate the #dadTechSupport :D Too funny
The heck is a technology librarian?
A librarian that specializes in technology...
Like you catalog technology?
Best I could find, without posting my own job description:

Aaaahh tech related to library operations and its patrons!
I find your videos so funny and entertaining ! Thanks for posting and being so awesome !
Happy to see 2 of my favorite youtubers join in a video. When i saw the title my first thought was to comment Mike boyd did it first! But then i saw you 2 were together. Awesome!
Diana why haven't we done a collaboration yet ?? " Physics Girl breaking a glass with her voice in Ultra Slow Motion". Perfect match !
Warped Perception do you have any idea how epic that would be?. Your cinematography with her voice and intelligence ? Wow
Ha! No one will collaborate with you WP, your stuff is too good, you leave everyone in the dust...
Майк влагалище I thought those two should collaborate for a while.
Warped Perception that would be sick
That may be hard to catch cuz the frequency is so High.
Your happiness and shock at 1:40- I had the same reaction. Your videos are always awesome!
I love the way you simplfy things 💓
Much love !!
I love the stunned silence that goes on and on for more than 10 seconds from 6:58, you look like a toddler that just saw a kitten pop out of a box for the first time ever, absolute wonder and astonishment. Priceless, thankyou for making my day.
or flick the glass a few times to 'check the frequency' when really you're trying to create those micro fractures
Here, let me check its frequency…
**proceeds to smash the glass against the table**
OMG, #dadtechsupport is too funny. LOOOVE your videos. If I had a physics daughter, I'd want her to be like you
She emanates gigantic amounts of goodness.
Thanks Dianna !! Brilliant & Honest demonstration of Resonance !! 👍🏻👍🏻
I absolutely love your videos You Are very easy on the eyes and very intelligent not a combination that is calming in this day. Thank you for everything you do
hey diana can you make a video on general realtivity? how gravity effects time, and all that stuff.
Great idea!
Vsauce did it already.
redstone craft guy Im surprised all of his stuff hadn't been moved behind that paywall yet. Anyway, Id much rather see a physics major do a video on the subject over a psychology major do a video about it.
6:57 I just loved the reaction and expression......
hey and i thought i was the only one 🤣 lmao
Thanks for learning this way I was so impressed by your proposed your ideas into practical, doing well dear.
I found your channel today and believe me i am exciting as you and giving same reactions to results. You are amazing.
Very nice vídeo! I'm Brazilian and learning English. Your videos are very good to learn new stuff and improve my English. Tks a lot!
This is so cool! I love this Channel!!!!!
It also helps if it’s crystal glass and not a normal wine glass as mike Boyd said in his video
So easy and enjoyable to watch. My daughters are also tech support for me. Your Parents must be proud of you. Love from Australia. Thank you.
Best episode yet Diana. Your face when the glass broke was hilarious. I am inclined to think that it was a combination of hysteresis and you finding the resonant frequency. As a note, if hysteresis is a factor, then the resonant frequency would have shifted as the crack grew.
Isn't possible to make this whistling? I mean whistle frequencies are "more pure" than voices, and it's easier to keep doing it for a long time. Did you try?
Most people probably can't whistle that high loudly enough to actually get it to break
Rockzilla1122 I can‘t whistle at all XD
I am teaching resonance now in two of my HS Physics classes. I agree that the swing is one of the best ways to simply explain how resonance works. We watched the MythBuster ep where they get a hair band singer to break a glass with just his voice. I never tried it, assuming that I did not have the ability to match pitch and get the. volume needed. This vid has inspired me to give it a try in class next week. I hope you are feeling better soon. My class is always was very concerned when we learned that you were struggling with health issues. All the best. Mike
Love you young lady!!!! I’m as old as your Dad! But I’m in to this stuff and still try to do my best at teaching our really young people!!
2018 looking good
Dianna, it might also just be a statistical thing too: you have to keep at it long enough to have let out the best pitch with the least phase noise for the longest time with the highest amplitude - like getting '7' '7' '7' after lots and lots of tries at a slot machine. So the real big test would be to pull out a brand-new wine glass, ping it with your fingernail to pick up its dominant frequency, then scream at it for only 5 seconds to break it.
love it. I study Physics and Music and it's fascinating. I love how you can explain it to anyone very simply.
I really liked that you also included a bit about the engineering side of this, that part was completely new to me.
You have a lovely voice, when does your album drop? :-)
6:57 that reaction though. .. . . .
Thanks for the great effort you gone through to make this video.
ee..........ee.e.e.e.e......e....e.e.e.eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Thank You Physics Girl for the demonstration of breaking a glas by singing a note. As an engineer and amateur mucician I have known this, but not being able to see it before.
You know I have to try this! Resonance frequency is fascinating stuff, collapsing bridges while walking in step and the like...Thanks for the video
Love your videos, keep it up
I have a question.
In movies or TV shows, they show high notes shattering glass (or crystal) from a significant distance. Is that possible or just "movie magic"?
I love all your videos. Please keep it up.
Depends on the amplitude (volume).
I would also imagine that it also depends on the structure of the building. Considering that most amphitheaters and opera houses are built in a kind of concave/dome-ish fashion, also helps facilitate that "movie-magic"
Suzanne Strickland juat mo ie magic
Just need to crank it until it pops.
So worth it just to see the look on your face when it works.
You make physics so fun and intressting thx
Could you theoretically break a glass with the octave (double the frequency?) of the resonant frequency, or would that decrease the amplitude?
Hydraulic Press guy voice: The glass is extremely dangerous, and it may attack at any time, so we must sing to it.
Ha Ha, nice reference.
love this channel
Absolutely amazing... Thank you for sharing 🙏🏽🙏🏽
6:56, and most of us are “ok, done”……
The part where Dianna has her headphones on and is just screeching had me dying, I was imagining what the neighbors would be thinking! This was amazing though!
I love how silent you got at ~6:55 and just cherished the moment when it broke.
You explain it so well! Thanks.
Big up Mike Boyd
You should go do a colaboration with the slow mo guys about this subject :D It would be really COOOOL ! Thank from france :)
Congrats!!!! That was awesome 👍
I love that sound it made as it broke, that weird ringing noise as the sudden size change altered the resonance
8:49
I can imagine your face Dianna... Whilst he explains this.
😯 wonder and 😀happiness
#Kyleneedsayoutubechannel
I think he kind of looks like Tyrion Lannister.
Totally XD
I died at 9:05
I love the way you went about this. Good job, nd really interesting
I´m a teacher at elementary school in Germany. You are the perfect role model for the girls in my forth grade class! I will highly recommend your channel to them. Keep up your great work and thank you very much!
It is interesting to note that the frequency at which there is maximum amplitude of vibration is slightly lower than the resonance frequency
Awesome, congratulations!!!
I know you said don't try this at home but, I'm sry I can't promise I won't. 😜😅🙏
I love your enthusiasm. Thanks for enlightening the World
These are good videos on science very useful for the students and the common people.
Actually, could answer your dads question... old people like us need to know!!!(;~ )
Mel: But you know we want to try this. Just don't tell my mom.
Can you do this in a lab setting using identical glasses but filling them with different liquids? Would be fun to see if the type of liquid used affected the glass’s resonating frequency.
I LOOOVE your videos!!
Is it possible to make a flawless glass ball that would bounce against the floor and come away unharmed like your engineering friend said?
h2 if you can somehow prevent all the cracks from forming perhaps. Glass does have high elasticity but due to the tiny cracks it always breaks before you can try to bend it.
Look up Prince Rupert's drops. As long as the tail is unharmed, nothing happens.
Here’s a burning physics question.
If the event horizon of a black hole is the point at which it’s gravity becomes too strong for light to escape; then would the proximity of 2 black holes cause each other’s event horizon to decrease in radius (essentially helping to pull light/matter/energy out of its neighbor)?
It would make quite an odd lensing effect yes.
When two black holes are close to each other, they would merge because of their mutual gravitational attraction and form a black hole with a bigger event horizon.
burning astronomy question: could you flick a fingernail at a black hole to find its resonance frequency and then sing at it to break it?
That's easy...the answer is....42.
i find it an interesting question, but u mean only in the side they are facing each other right?
well.. i'm thinking no... it doesn't... because if you think abou it just like a distortion of space-time fabric and not a force doesnt seem reasonable that the drop one cause would uplift the other enough so some matter could escape it.
i'm visualising more like those sheets and balls examples, but u get what i'm saying?
That explanation about glass being supposed to be extremely strong was pretty mind blowing.
Also, glass has some internal stresses and this can be seen with polarized light. It is why you anneal glass after working with it. It might be interesting to see if you can watch the stresses build in the glass with cross polarizing filters.
Also I found it interesting that the brand new glass broke near the stem as opposed to the rim.
