Sound + Fire = Rubens' Tube

[@AthEater]

guess you can say that mix tape was fire

[@AlonescapeRS]

+Naithan Pangan omg why.... xD

[@Keagan14541]

+Naithan Pangan ( ͡° ͜ʖ ͡°)

[@Akira-Aerins]

Tiasu! You mean Tiasu's song/album, right? The one named Fire?

[@Akira-Aerins]

+Justin Elliott umm... *: Fire (without the question mark, just to clearify.)

[@rev2235]

IT WAS LIT

[@bo_broadwater]

The Rubens' Tube was my first introduction to just how amazing physics really is. I saw a different video of one about five years ago, and I asked a professor at my school if we could build one. We did, and I have been hooked on physics ever since. Now I will start my physics PhD in the fall. If feels good to look back on my original inspiration. Thank you so much for the great videos, Derek! And thank you for inspiring others to think about physics.

[@nyarro8370]

That music was "lit".

[@bts-bt21army32]

Justin Arro XD

[@kentslaymaker9254]

And... I'm off the watch The Fifth Element

[@veritasium]

@mrhashbrowns the effect is something called a standing wave - where the traveling waves are bouncing back and forth in the tube and creating a consistent pattern.

[@-_-_415]

If you look really closely , You can see that it's not acctualy him singing

[@StrategicCat]

+Richard BNmedia *facepalm*

[@willa4you]

Of course not: the sound of the orchestra is coming out of his mouth when the other is taking the sound of a voice out of the air by flapping hands.

[@4ltrz555]

Should I woooosh you?

[@FoxMaster]

strat r/wooosh

[@randomthingch1970]

NO I Look Really Far Like 10 KM IM NORMAL PERSON AND I CHOOSE METRIC!

[@veritasium]

it is both a longitudinal wave and a standing wave. A standing wave just means there is a forward-going (compression) wave and a backward-going (compression) wave to produce points of maximum wave amplitude (anti-nodes) and points of no wave amplitude (nodes).

[@whopperlover1772]

Imagine cavemen like lining up their torches in a row and then start singing....prehistoric audio visualizer.

[@prosincr]

Doesn't really work that way lol.

[@whopperlover1772]

Dilip Tien Kinda a joke....

[@veritasium]

sound waves compress and spread out the air, so they do affect the air and gas pressure.

[@vesteel]

[@michaderstricha]

why is that veritasium guy acting as if he had no idea of anything ? :o

[@Scerttle]

I assume to give a viewer who doesn't know someone to relate to?

[@vincentsmit9538]

M Tenik so he can ask questions explaining it

[@mateusleal5943]

@@Scerttle dont have to play dumb to do that, simply ask questions

[@csicee]

Mat Loyal he is

[@veritasium]

that's right because here they are forming a 'standing wave'

[@mainlytrombone]

Now that is SO COOL. I've always wondered how to visually represent longditudinal pressure standing waves! Wow, that sounded geeky! But very true ... Not sure if I should admit that ...

[@veritasium]

yeah, there is a copyrighted piece of music near the end. I'm thinking about cutting it out and reposting it...

[@BiggieMackDaddy]

I made one of these for my high school Physics class. I used sin waves to test it and calculated a reasonably accurate speed of sound. It was really cool.

[@bmxwright]

my physics teacher did this last year and he played dubstep on it. possibly the coolest experiment with soundwaves in physics. this is why i love science

[@nazriljimmy2688]

"All the other kids with the pumped up kicks You better run, better run, outrun my gun"

[@oddlycreative8587]

Now to just put on some dubstep and DROP. THE. BASS

[@jerrymores5261]

Lauren Berry No.

[@Akira-Aerins]

+Jerry Mores it would be amusing at very high volume--maxxed out, actually--so the fire better displays the sounds being played. You can always mute/min your speakers/sound mixer/in-line volume control/KZbin video/browser if you want, and just watch the fire. Alternatively, play the Monster Cat Twitch stream into it at high volume, for science--or just plain fun, but other people would want to see that too!

[@jamesappleface4833]

3:17 if you look closely you can see that's not him singing

[@mugicha9596]

Really?! I didnt catch that

[@matthewrogers4282]

You're hilarious. Real comedic. I'm serious. That was funny.

[@marloscatos3001]

Plot twist: He was actually singing the song but he was so good at singing it that it appeared as if he was not singing the song correctly.

[@iRoNiCxFaTaLiTy]

I cant believe that both of you guys produce the same voice!

[@abdulrahman7508]

Imagine this in raves to look like a sound visualizer omg xD

[@SaurabhPatil1]

That was amazing demonstration of sound waves in air!

[@claylindsay5821]

One word. Dubstep.

[@LucaDeflorian222]

This is one of the coolest video I've evere seen in my life...i love this channel :)

Best way to demonstrate standing wave ever!

[@hrw2003]

That eye contact. otp

[@BlaizeV]

This was so Great! The addition of Mozart's Queen of the night at the end made this video. Couldn't have picked a better song to show this thing off

[@WarpPal]

This is ironic because thats exactly what the wave visualizer looks like in media players

[@luunnmusic]

WarpPal what makes it ironic?

[@WarpPal]

Luunn If you've ever seen the visualizer on any Media Player, thats what some of them look like

[@luunnmusic]

WarpPal yes, but that isn't irony..

[@sunnysideup137]

WarpPal thats not irony at all

[@WarpPal]

Halloween137 It is ironic because is looks almost exactly the same

[@BlackRi07]

Because, the source of the sound is coming from the left, and traveling to the right, but with the constant tones for example, the exact same wave length is being sent through the tube. Because it is the same each time, it hits the same highs and lows at each point, so that it doesn't appear to move. if you could see other other things, like the vibrations traveling through the tube, instead of the sound waves, you would be able to see them (the vibrations that is) traveling from left to right

[@swaggysalamanderproduction7328]

I'M WEARING HEADPHONEZZZ I AM GONNA DIEEEE

[@Vitorruy1]

MoonDragon I'm hearing headphones and I'm fine, I guess you're using your headphones with the sound too high.

[@TheLaserPhyco]

this was uploaded in my b-day!!!

[@travis51killer01]

is better with dubstep

[@jerrymores5261]

javier humberto moreno maldonado Expect dubstep isn't better since no one likes broken robot music.

[@travis51killer01]

Its my taste not your, but really mean that the effect, for me, is better using dubstep.

[@jerrymores5261]

[@natesavi4216]

Mixed compressions traveling through a tube with small holes with burning gas = Awesome priceless visual equalizer.

[@gaimz1855]

Wow. That sound sure is annoying.

[@scrumblesbumbles7692]

Yeah, and that long tone was bad too.

[@aloywkd]

about 60 years of natural gas left and you guys are doing this...love it.. :D

[@hirukgaming1038]

Still 50 years of natural gas left?

[@NikosOla]

Omg they are so nerdy 😂😂😂

[@Tunatunatun]

These are mechanical waves, they spread out through matter, like air, gas, water, etc. as you push the particles together they have a higher pressure, and when you pull them apart they have lower pressure. Waves are just the switching of high and low pressures, when something vibrates it compresses and discompresses air.

[@mediocreproductions4938]

Who's here from grandayy?

this is just beautiful and out right ingenious

[@Akira-Aerins]

lame lip sync sucks. ...an alliteration that aspires to avoid the event entirely.

they sing so beautifully!

[@tjridley]

music plus fire = AWESOME!!!!!

[@fakjbf]

My friend made one of these in his physics class. His teacher gave him a 100% on his semester exam because it was so well done.

[@notfree25]

So that is how those equalizer things on the stereo works. They are pumping digital gas thru my stereo! Genius!

[@Dixavd]

THey should show sound waves like this in school - seriously visual and getting people to sing or change the sond and see the results coudl really help - heck it coudl help music lessons. awesome.

[@whereisrahul]

I made this with a friend last year. It is simply awesome!

[@Felaris]

BEST. VISUAL EQUALIZER. EVER.

[@ImAnDride]

You guys are such geeks, love it.

[@AlixPass]

My science teacher in 7th grade did this. He played some metal, and it was just plain epic.

[@audiobahn404]

Because the wave length of the lower frequencies is about 20 meters - way longer than the pipe, so you would only see a slight upward or downward slope. It would basically be like a seesaw. Then the higher frequencies wouldn't be strong enough to counter-act the lower ones, so they wouldn't do much. Lastly, since you'd probably have the bass up too far, the flames would likely be extinguished before too long.

[@cameffect9443]

This is beautiful. Thank you!

[@TheYahmez]

I want that in my room! at night! with a couple of little love making tunes and the lights out ;)

[@GiorgioPresti]

That's probably a standing (or stationary) wave. This is also the reason why some frequencies are not shown, the column of gas cannot vibrate that way in that volume.

Equalizer visualizes the the strength of output signal (in db) per frequency. Whereas Oscilloscopes does exactly what the tube in the video does: it shows actual sound wave (pressure of air) per time units.
