Mythbusters Glass Break

[bilabili]

now melt a plastic cup with your voice

[lancertelstar]

@bilabili mabey with his breath

[EvilNemesis1992]

@hehehayhay yeh it is... not please die

[akkiekipbaby]

and how about justin biebers song ?

[GooberSuess]

@akkiekipbaby ITS NOT IDIOT GET OUT JUSTIN BIEBER FAG

[EvilNemesis1992]

@hehehayhay why dont you, hmmmm, die?

[SteubenDesign]

As long as it wasn't Steuben Glass, I'm ok with it. lol

[tntparanoia]

Strong sunglasses he got :O

[UnholyMasterOfMetal]

Omg people this has nothing to do with how many db it is. The glass breaks because he is hitting the resonance-frequency of the glass and thereby inducing a resonance catastrofy (the sound waves adding up when bouncing back and forth) breaking the glass at some point. It's easy if you know the frequency really.

[venderaj]

PS- that glass only took 105db. I was registered at 120db at 1 meter, which is the correct distance for measuring sound.

[venderaj]

If Vitas broke a glass Ive never seen it. And I guarantee that many people have broke a glass way before. We humans have been stupid for centuries and someone as goofy as me has tried this the day a crystal wine glass was first created;)

[LinkinYM]

dude, 105 db?! a jet plane taking off is about 120! oh well, i can scream at ~120 anyways.

[PrincessLindie55]

im doing this for my science fair project. i have a loud voice and i know what i have to do. this'll be interesting! :D

[HalcyonSkies]

He's the first yes, but this guy was the first to do it ON TV.

[peterkframe]

@HalcyonSkies thats wat she said

[DominationSupreme]

GET SMARTER.

[ferrariguy1988]

Jaime Vendera is the man

[waparker4]

guy splits the atom with his voice.. cue nuclear explosion

[sqeebelee]

dude you win haha

[vincentws03]

bad physics but good humour

[lukesrevolution]

Check out Rhys Morgan doing it.... the guy freaks out at the end! lol

[Caleb5617]

the glass has a natural frequency, once reached the sound splits the atoms apart causing the glass to break

[ff5500]

5056 Hz!!!? and 105 dB ?!!! omfg!

[bergkshire]

556 not 5056

[MatthewPatch]

105db though :O

That's loud for a human voice

[EDERDUDE]

hes a singer

[DJPeroxis]

lol for real! a lion's roar i think is around 114db so 105 from a human is impressive O.O

[Empis1991]

Nah, i can scream in ~115dB

[kansterstrak]

I've seen this part too :)

[AdobeExcel]

does that mean that the higher the pitch, the sharper the soundwaves, and the easier it is to break the glass? sorry i'm not very good at physics.

[waterbender25]

The higher the pitch the faster the soundwaves travels and hit the glass, which causes the glass to physically vibrate (as you can see in this video) and eventually break.

[lonelybaka]

almost correct

higher the pitch more the vibrations; the glass catches these vibrations and vibrate back and forth so fast that it breaks.

imagine trying to bend it in both directions very fast.

[ErkudenSyn]

actually... it breaks because the glass on its solid state istn veri flexible... so the vbratons make the glass move back and fort as u said... and it breaks... that simple..

[Bklynballerplaya]

Lol dude u dont know what your saying. He gave a good explanation

[vincentws03]

keyword = resonance

frequency of voice superimposes with the natural oscillation of atoms causing them to gain kinetic energy hence break

[EvilNemesis1992]

@vincentws03 did u get an A in your GCSE Physics? 

[azball321]

@EvilNemesis1992 more like a masters degree :p

[Idontfeelonce]

@vincentws03 no, not in atoms... Its the molecules of the glass material that do forced oscillation in the best frequency so as to succeed the biggest oscilation with the highest height=A..

[thedarkembassy]

@vincentws03

also the microfractures already present within the glass ...

[sqeebelee]

the pitch has to match the glass's resonance. like that old video of the bridge where the wind hit the bridges resonance and made it do waves till it ripped itself apart. weeeee

[RageDeRuin]

heh, yeah, yay Tacoma Narrows Bridge. at least they rebuilt it to NOT match that the same again..

[sarahlambo]

actually, glass breaking doesn't depend on the loudness of the voice as the pitch. all objects vibrate with a specific resonance. if you can reproduce that resonse- in other words the same wave pattern as its natural resonance the two waves will add to each other, and at a certain, the amplitude becomes too big and the medium of the wave breaks, or in this case, shatters.

[xXTOLOMITEXx]

In theory, amplitude is irrelevant. However, in the real world, you need both the correct frequency and larger amplitude. If the voice is not loud enough, it will take a very long time for the waves to sum up to a point where the glass breaks.

[miasr55]

Explained Very Well, thank you.

[babonilla]

hey you know i saw these two british dudes do it in Nat Geo Channel and they said it wasnt possible. Then two days later i saw this and they shut them up.

[kilolana]

I watched the show...It was funny when Adam tryed...he kinda sucked

[KWSolver]

he's jim gillette??

[ozzymeetsjesus]

No, he's Jaime Vendera. Vocal coach god.

[kondr7]

IMPRESSIVE !!!!!!!!!!!!!!!

[pikemaster92]

it looks just like a robot from star wars

[Ryeran]

The first time in recorded history. Nice.

[taakepus]

jim gillette rocks

[Slance1]

yes he does, in this episode they showed Nitro and Jim Gillette a little :)

[Hardrockinamigo5]

myth busters is sweet

[amario710]

wow. just wow.

[cheapazzprouductions]

i can break glass with my farts. sometimes thou it stains glass instead.

[DevinShadowV]

I know when I saw that for the first time my jaw went to the floor

[2007FORLife]

Omg you should go on Guinness World Record!!!!!!!!!!!!!!!!!!!! jaw is actually able to DROP

(Sarchasim)

[DevinShadowV]

lol even if I tried I'm like jamine or adam I can't get the right tone and hold it.

[fdota]

Sarcasm

[politix11]

i loved that episode!!

[helloduo]

i saw that episode..i was impressed

[Cybrok]

Now THAT is impressive.

Anyone can do it with a speaker, but this... wow.
