Cody, thanks for the shout out! We first saw this phenomenon demonstrated by professor Poliakoff on Periodic Videos. Its interesting that both of us provide the physical explanations for these effects and haven't even been offered tenure. Love your videos!
The volume difference is due to conservation of momentum. There are the same number of molecules displaced by the finger snap in each gas (at the same pressure + temperature). The lighter helium molecules can't transfer as much momentum to the air outside the bag.
My guess is you would observe the same thing without the bag. The heavier gass has an impedance closer to that of the moving fingers, so more energy is transferred i.e. louder snap.
You would absolutely love TechIngredients, Cody! This explanation is given on that video, as you know, but the rest of the content is up there with you, NileRed and the rest of the good science youtubers! Super high quality, would love to see a collab someday... edit: Oh, I see another comment said the same thing, lol.
While normal people at 5am are tucked up in their nice warm bed, Cody is in the freezing cold snapping his fingers inside plastic bags filled with various gasses.
I accidentally spilled the contents of a (lit) alcohol burner over a table when I was a kid. If that ever happens to anyone, make it your first instinct NOT using a blanket to put it off. ^_^

Little experiments like these are why your channel is so awesome. I love your curious mind, and your hunger to just see what will happen. This experiment has very few (if any) practical uses, but I loved every second of it.
It´s cool to see something else go through a pitch shift with those gases than just your voice. That made it a lot more interesting to watch. Also be carefull where you snap your fingers at.
I just came from watching some videos from Backyard Scientist, Techrax, King of Random etc, and I just wanna say : Thank you Cody! Thank you for great content. No stupid generic music, no clickbait, no exploding water melons, no wasting stuff for the sake of likes. You deserve all the followers you want. Keep up the great work, once again thanks for all the great content.
They'll sound pretty much the same pitch, because it's not actually the pitch that changes but the resonant characteristics - the "formant". What will change is the bass port tuning and some of the Thiele and Small parameters will be skewed. Lower density gases makes it easier for the speaker cone to move, for instance. The speaker may take on a different "tone", like changing from a bigger speaker to a smaller speaker. It would be a cool experiment, nonetheless!
Some blending of science and music for you. When I am working with an ensemble I need to tell my students who play lower instruments to play shorter and more detached for their sound to sound equally as clear as a higher pitched instrument. You can hear when you snap in the halon the sound is longer as well as louder. While we are playing in the same atmosphere the wavelengths produced by my lower ensemble members are longer so they "linger" longer just like you hear in your experiment. Really cool to hear that in here. Thank you for sharing!

I'm glad you mentioned Tech Ingredients But honestly I'm quite surprised you're not subscribed already. They're right up your alley ... an all your viewers alley as well.
I was so fascinated by your experiment I did not even saw all the things disappear. When the rings disappeared I saw it, you would make an amazing thief! Amazing videos and quite fascinating. Greets from Germany!
So by Tech Ingredients explanation, if you put an extra bag around the helium filled bag and filled it with halon, the sound would be nearly silenced because the helium atoms would barely be able to move the halon atoms. Right?
Exactly. I think that is the reason why sound barely traveled through helium. I think since helium atoms are very light, they could not move the heavy walls of the bag much hence the passed energy is very little. Since halon is far heavier than helium it can easily vibrate the walls of the bag and we heard the sound louder.
But surely cody would be exerting aproximately the same amount of force, so the helium atoms would move faster. Then they would have the same amount of energy as the heavier halon molecules that were moving faster, so it should be about the same volume.
Cody, you're the biggest dork for that disappearing trick. Even with your boundless explorations of science, I can't help but giggle at the little things like that.
The happiness when Cody discover something new like the sound of the snaps is unpayable, actually is payable, just become a patreon to help him post more videos hahaha it's so educational.
Cody I loved how you snapped everything away one snap at a time and I thought that was a brilliant idea how you made us see it but yet not see it at first I thought that was brilliant anyway I love your video keep up the great job you're doing thanks from a long time watcher, love all your videos.
@@MRblazedBEANS, I use it as a so called natural cleaner for food items. I'd agree 100% good quality vodka is better, and everclear should only be mixed.
Everclear is highly distilled Ethanol with zero additives (It hasn't been denatured), so I think a bottle for around $22 with a little salt to pull out the remaining water is a good deal for getting a pure alcohol without bitterants or foreign alcohols to "denature it" as well as it doesn't have a higher water content like isopropyl alcohols which are typically are found in 50-96%.
denser gases/liquids carry vibrational energy further, helium is significantly less dense than Halon, so the sound energy won't transfer to the bag and out into the surrounding air as effectively as Halon will. Water carries sound faster and further than air. I'm sure others said the same. Cheers, another great Vid!
A question Cody, you said(I'm paraphrasing): "sounds waves will be travelling slower in halon because it's heavier than air" I always thought that sound waves travel faster in higher density/weight mediums? Doesn't sound travel faster under water than in air? Am I missing something?
Sound travels faster in water not from the density but from the greater strength of the intermolecular forces. Stretch a long rubber band slightly and give it a flick, it forms a wave that travels down the band, now stretch it tight and when flicked the wave moves much faster. The speed of sound in diamond is way faster than it is in gold.
@@theCodyReeder If that is the reason then why is the speed of sound faster at sea level, where air is denser than at the stratosphere, where the speed of sound is slower?
@@zoperxplex because at sea level the air is at a higher pressure, with more particles per cubic meter so the particles need to move less far before colliding and transferring the wave energy to the next particle. (Edited to correct my incorrect use of the word denser)
Hi Cody! Nice infinity bag, btw after hearing the dense sounding snap, it makes me wonder how a gun or a explosion would sound like going off in the dense gases
5:52 also, in the boundary between the air and the bag, the halon pushes the bag with greater force, therefore making a louder sound. The inverse happens with the helium, low force, because helium has almost the littlest mass possible, so it pushes the bag with less force
Mostly it's the water that by evaporating carries away heat, just like when your sweat evaporates you feel cooler. Also gas expanding out of your lungs and mouth will get colder. Lastly you emit heat in the form pf infrared radiation, altough this process is much slower
technically speaking only the surface of the person freezes, as noted by others mentioning evaporation and such. The internal body temperature will in fact climb for a while until something stops it, like the person dying. This is one reason space suits have cooling systems, and why the computer equipment involved on spacecrafts need to be carefully designed to generate minimal heat, instead of just using off the shelf high performance processors. A normal computer under normal use conditions, in the vaccuum of space, would eventually melt its own circuits, as there is only infrared radiation to lose heat by. Things that generate their own heat, tend to get very hot in space, before they get any colder.
I have another explanation. Helium sounded less louder as there is less molecules to transport the sound wave. Halon sounds louder as there are more molecules to transport. Like putting two balls on a pools table or many. Haven't figured out what is causing the pitch change.
There is the same number of molecules in any given volume of any gas at a given temperature. I know it’s counter intuitive but when you calculate out how much space there is between gas particles it makes sense.
The pitch change is pretty simple to explain :) You have an acoustic chamber (in this case the region in Cody's hand where the sound waves are developing) of a particular and relatively constant size (think of this in the context of your larynx for when you speak after inhaling various gasses), and as you increase the speed of sound in the medium by using a different gas (in this case helium) the pressure wave generated by the snap of the fingers is able to propagate faster. This faster propagation, or conversely slower propagation for a medium with a slower speed of sound, leads to a pitch change (higher for higher or lower for slower). As to the volume change it merely comes down to the amount of work imparted when generating the pressure wave. The greater density gas requires more work to displace the same volume of gas and so that pressure wave will have more energy which in turn means more volume.
Referencing to 5:10 I think it would be amazing to see you coat the table with asbestos. I'm sure many people would like to know how to fireproof their table.
Well I sure hope that “bag + gases” does not equal to a homemade infinity gauntlet. *Oh no...I DON’T FE E L S O G O O D* Edit: apparently yes, since while reviewing the video, items on the table were disappearing from the table.
It's louder because the denser air is able to create more powerful air pressure waves, the movement of air is what we hear as sound, so if what your moving has more mass and your moving it at about the same speed(it does slow down a bit), it will have more energy, and of course since the helium has less mass it's pressure waves have less energy and thus are quieter.
Cody, you can impart more energy in to a higher density medium. Just like you can punch a sand bag harder than a baloon. In acoustics this is described as an impedance difference. The moving object has a lot of mass and the medium (air) is comparatively lower so energy is not efficiently transferred. As the density of the medium approaches that of the source, energy will transfer better. Same theory as impedance matched transmission lines fur electrical power transfer.
I love how you are honest about when someone else has the same sort of idea before you. It could just be coincidence, but the action lab's "black fire" video has quite a few similarities to a video on the zeeman effect by applied science. If he realises this, he should at least link it as educational material on the effect because the goes in to quite good detail about the effect.
A more technical explanation for the change in volume is that the acoustic impedance of your finger and palm is much higher than that of the air. For Halon, the discrepancy is smaller so more of the energy can be transferred from the solid to the gas. For the pitch, it depends on how much of the sound is produced by the air and how much by the "instrument". A flute or human voice would sound much lower in Halon, but a guitar or xylophone would sound about the same.
Periodic Videos did a video last year where they put a cellphone in helium to see how it changed the sound coming from the speakers, the video is titled "Helium (some extra stuff) - Periodic Table of Videos" They have a good explanation on why the helium atmosphere made the sound quieter.
I liked the way the table magically cleared itself when you snapped your fingers. Getting the helium or halon would probably be more work for me to repeat the trick than just clearing the mess manually.
I think you can explain the different sound volumes with the energy conservation rule. Low pitch pitch sounds (low frequency waves) transmit lower energy than high pitch. Since you use the same energy for snapping fingers in either gas, the volume has to be higher for low pitch sound in order for the energy to be conserved.

Quick question how does a person freeze in space when there are almost no atoms to transfer the persons heat
You've just made outer space safer by asking that question.
Beacause of the infrared emissions of the person
Mostly it's the water that by evaporating carries away heat, just like when your sweat evaporates you feel cooler. Also gas expanding out of your lungs and mouth will get colder. Lastly you emit heat in the form pf infrared radiation, altough this process is much slower

The pitch change is pretty simple to explain :) You have an acoustic chamber (in this case the region in Cody's hand where the sound waves are developing) of a particular and relatively constant size (think of this in the context of your larynx for when you speak after inhaling various gasses), and as you increase the speed of sound in the medium by using a different gas (in this case helium) the pressure wave generated by the snap of the fingers is able to propagate faster. This faster propagation, or conversely slower propagation for a medium with a slower speed of sound, leads to a pitch change (higher for higher or lower for slower). As to the volume change it merely comes down to the amount of work imparted when generating the pressure wave. The greater density gas requires more work to displace the same volume of gas and so that pressure wave will have more energy which in turn means more volume.

Well I sure hope that “bag + gases” does not equal to a homemade infinity gauntlet.
*Oh no...I DON’T FE E L S O G O O D*
Edit: apparently yes, since while reviewing the video, items on the table were disappearing from the table.

Love you cody
Cody snaps, objects on the table fades away... while he laughs with his make shift chemistry gauntlet
I love his laugh
It's louder because the denser air is able to create more powerful air pressure waves, the movement of air is what we hear as sound, so if what your moving has more mass and your moving it at about the same speed(it does slow down a bit), it will have more energy, and of course since the helium has less mass it's pressure waves have less energy and thus are quieter.

Cody, you can impart more energy in to a higher density medium. Just like you can punch a sand bag harder than a baloon.
In acoustics this is described as an impedance difference. The moving object has a lot of mass and the medium (air) is comparatively lower so energy is not efficiently transferred. As the density of the medium approaches that of the source, energy will transfer better. Same theory as impedance matched transmission lines fur electrical power transfer.
You should try putting a speaker in halon and helium
Christopher McDonald That's a great idea! I concur.
I love how you are honest about when someone else has the same sort of idea before you. It could just be coincidence, but the action lab's "black fire" video has quite a few similarities to a video on the zeeman effect by applied science. If he realises this, he should at least link it as educational material on the effect because the goes in to quite good detail about the effect.
snappy quick to reply
Amasing 😊 😊 😊
Thanks for making these videos, always inspiring to watch

A more technical explanation for the change in volume is that the acoustic impedance of your finger and palm is much higher than that of the air. For Halon, the discrepancy is smaller so more of the energy can be transferred from the solid to the gas.
For the pitch, it depends on how much of the sound is produced by the air and how much by the "instrument". A flute or human voice would sound much lower in Halon, but a guitar or xylophone would sound about the same.
Cody would be a great great chemistry teacher like if u agree
Nice video Cody Slav, subscribed!
you should take a recording of your voice and put it in there
Periodic Videos did a video last year where they put a cellphone in helium to see how it changed the sound coming from the speakers, the video is titled "Helium (some extra stuff) - Periodic Table of Videos"
They have a good explanation on why the helium atmosphere made the sound quieter.
Put speaker into this blasticbag(with helium and halon) and play some music!!! :-)
I didn't notice the stuff disappearing until it was almost all gone...dang you're one sly magician, Cody!
Mr. Cody,
I don't feel so good...
I always thought snapping fingers noise came from your finger hitting the area below your thumb, you learn something new everyday
Sorry, Cody. The little "things disappearing" gag was great, but you can see the cut in the middle of the table where the color changes.
I liked the way the table magically cleared itself when you snapped your fingers. Getting the helium or halon would probably be more work for me to repeat the trick than just clearing the mess manually.
I can't snap my fingers :(
Maybe I just need a bag of halon around my hand
Slam a door on them hard enough and they'll snap ;)
@@gravijta936 I'll go try it now, will post results
It worked
Try a metal gauntlet.
I think you can explain the different sound volumes with the energy conservation rule. Low pitch pitch sounds (low frequency waves) transmit lower energy than high pitch. Since you use the same energy for snapping fingers in either gas, the volume has to be higher for low pitch sound in order for the energy to be conserved.
Very cool experiment. May just be my favorite one yet.
Cody's probably the only guy who can make something as simple as a finger snap so interesting.
Other than Thanos, of course.
