at 1:11 a message shows up for about one frame. i turned the speed to .25 and found out its just warning us about a glitch in the video, that it shows him reading the script for 1 frame while its supposed to be in the cartoon.
I actually did not know about all of this, until I went to get helium balloons for my kid's bday, about a year ago! They didn't have helium, and the sales clerk educated me (THANK YOU!) I'm proud of my kiddos. 😍 After explaining to THEM why I didn't have the balloons that day, they no longer want them!👍😍
We should use hydrogen instead, so that more children's birthday parties explode. This would help solve the global population crisis AND give more of the upcoming generation's members the resiliency to cope with trauma. It's win-win!
@@ThePeterDislikeShow it may not actually be THAT dangerous in small amounts, but the amounts get larger as you move back from purchase, to origin. So, the store selling it will have a large tank of it. The large tank will be refilled by rather large tanker trucks. The trucks get filled at the refinement/processing centers. And there's the collection process, etc etc. So, I'm not sure it would be worth all of that? BUT, it MIGHT be worth investing $ into safety and problem solving all those points! It might someday be a viable option, IF there's enough motivation to invest into it. Btw, read *EnvisionerWill* comment. A real sweetheart, ain't he? Not sure what, if any, point he's trying to make, like maybe he's just voicing how dangerous he thinks it is. But. Yeah.😖
Helium 3's also REALLY useful for ultra low temperature research (unlike He4, it's a fermion rather than a boson, and can be cooled to way, way lower temperatures :D ), but damn is that stuff expensive XD
Helium is less dense than regular atmosphere (so all/mostly helium 'air' versus regular atmosphere), so when sound moves through it, it moves faster and is less compressed as a result. Same way speeding up a sound, like the Chipmunks, makes it higher pitch.
*CHECK* Check 1:12, for an instant something different is on the video; it says "V.O full screen gfx" and also an image of him reading a paper booklet. It's like a millisecond.
Editing problems. The editor didn't match the following animation with Hank's voice over to that timeframe, so it starts a tiny little bit later, but enough for the placeholder text to show up.
Question: how come we can't replenish our helium supply from alpha particles? We produce those all the time in particle accelerators and radioactive decay, and they are basically just helium nuclei; why can't we aim an alpha source at a collector, wait for the particles to snag electrons to make themselves neutral, then vacuum them up and store them in tanks?
because your MRI and floaty balloon would cost about 1billion$. We need to make nuke and eventually fusion electric which might be able to add a supply of He and He3. I know lots of people joke about this but in about 3-4 years, its gonna become a serious issue.
I had a conversation with Taylor Wilson when he came to a TedX conversation in my home city that I went to for free because I'm a student, and it was just phenomenal talking with him.
Almost 50 years ago my dad was a manager for Kresge's before it morphed into Kmart, he showed us boys this, and it was really funny cuz we sounded like cartoon characters!!!
@drumline17 it's a unit we covered in grade 12 chem. Maybe I translated it wrong since I take chem in french but it was "chimie electrique" so I assumed it was electric chem. We covered stuff such as the function of electrolytic and voltaic batteries.
I found the easter-egg! During the 1:11 second, the editors screwed up and it's this shot of Hank reading the script, with "For every atoms of atmosphere" around him and "V.O. full screen gfx" in a different font on his torso. I just rapidly paused and un paused with the space bar until I found whatever it was my brain told me was between that graphic and the next scene.
I read an article in a magazine about that kid. I think it was about him making some crazy furnace ( for lack of the right word, maybe arc reactor? ) that could make plasma.
Hank, your helium voice is freaking beautiful. Also, you SHOULD do a whole episode on that guy, cos he is awesome, and I want to know more than what I read in this one magazine .___.
Sound travels really fast in helium, something about 1000 m/s. So, if you look at the waves equation, you'll see that the higher the velocity, the higher the frequency must be.
The speed of sound is higher in helium than in normal mixtures of gas in air. Because of this, whenever you speak with a lung full of helium, your voice projects at a higher frequency than normal.
I have to correct you there. In fact we already know how to do it, but the output is less than the input so it's not worth using it on massive scale since we'd only be losing energy. In about 20 to 30 years, physicists will have found a way to do 'cold fusion' which is fusion at a lower temperature so it will be profitable.
Oh, one more thing: there is a real explanation for the sharp rise in He prices, and it can be heard if you search for NPR's "The Weird Story Of Why Helium Prices Are Going Through The Roof" It has to do with the FHR, as mentioned in this video, but it's not as simple as one might think. If you wanted my sources, data on Helium reserves and production can be found at minerals.usgs.gov Lastly, kudos to Hank and the SciShow team for doing a great job and (usually) getting their facts right!
hank you should explain about the property called superfluid of hellium it is one of the most baffling physical mysteries. and not mention amazingly cool.
Quick question. Unrelated. It there was an outer hull of a ship, separated a few inches from the normal outside of the ship by nothing (a vacuum (WHY ARE THERE TWO U'S?!!?)), will it float better? Because I'm pretty sure that assuming you put it in something strong enough not to implode, a vacuum floats pretty well.
Scishow is one of the few things you can start watching on youtube and end up learning something, instead of ending up watching monkeys make crack or somewhere worse like a miley cyrus video. I never fine myself saying 'ok enough internet' while watching scishow ! .
can you explain how MRI machines work? i mean, i know about the big rotating magnets, but where does the helium come in? maybe an episode on different medical imaging machines and techniques would be cool!
@Kisa Sohma that my friend is a compound not an element every element wants a full valence shell which is 8-whatever its maximum is, so sulfurhexaflouride is something wiith 13 valence electrons but it can have upwards of 16-32 I believe I'm not sure though
@roxx0n Hello Steven from Germany! I agree that covering the string theory is a great idea...but you first need to identify which one as there are many and it's really complex and we don't actually know if it (them) could work.
@ChannelCassie Yes, she did. I did not refute that fact. Im saying that helium in an unpressurized state (ie, balloons), do not pose a health threat unless you somehow manage to suck enough of it in so it replaces all the oxygen in your lungs, and even then it wouldnt cause death. The chemical properties of helium itself didnt do anything (like carbon monoxide or something would), but rather an obstruction in a blood vessel caused by inhaling helium from a pressurized tank.
I've got some bad news about 2020, and it's not about running out of Helium.
Not in 2023 either 😅
@@marianna5632 Haha, I'm counting the day, Matey.
A bit of helium walks into a bar. The bartender says "sorry, we do not serve noble gases here" ... the helium does not react. 😂
Michael Hummel LMAO
Ive been dying from thie joke for 10 minutes, i dont know why, its so bad but so good😂😂
How could you do a helium episode without explaining why it changes your voice! That's one of the best parts!
Oh I am so glad clean shaven Hank reigns today :)

No he does not have beards at all🤣🤣🤣🤣
Welcome to the age of CURLY HANK- iykyk
Wow, much like a fine wine, Hank has certainly improved with age.
sorry if we've offended with this categorization. we will put it in both playlists. best wishes.
Was Hank stoned in all these old videos?
Scishow commercial before a scishow video = win
1:59 "run out of helium by 2020"
Watching this currently on 2021, and we still got Helium buuuut theres a shortage of it
When you are watching in 2020, ffffffffffff*
well it's still fine for now
check it your self
Damn mustache, Hank!
So how's the situation of Helium now that we're closing on 2020? (still have a couple of years though)
+ Yeah would like an update!

hi from 2020! we still have helium :)

its 2020 now

So... now in 2021 and I'm curious as to what became of our helium stash.
Your 'Lando/Star Wars" comment is just one of the many reasons I like to educate myself with your show

its almost 2020 😳
xoxo IT IS !!!!
When you realize
It’s no longer 2020

theres about five months until 2022
@Cinos NOO I ONLY HAD LIKE 6 MORE SOULSTONES FOR PUMPKIN PIE COOKIE
Hank + helium = awesomeness².
dang it I thought it was 0.000529%
Yeah, I got 0.000531. So close
I thought it was 5%
+Hot Dog Okay that's crazy talk
6%
I actually guessed anywhere from 0.001% to 0.003%. I was in the ballpark but still pretty far off.

Quick! Everybody try that high pitch voice trick before we run out!
then we'll run out even quicker yunno
You can always do that with hydrogen. Bonus, you can burp flames.
Thanks! I've always been curious about that.
Almost 50 years ago my dad was a manager for Kresge's before it morphed into Kmart, he showed us boys this, and it was really funny cuz we sounded like cartoon characters!!!

Is it just me or does his high voice sound like steve buscemi's?

2 years now
I can't speak highly enough about this video
I am going to graduate from high school in 2020 I'm in 7th right know
Keep up the good work and don't cave into peer pressure.
Give literally zero shits about anything anyone says, but focus on what you want instead.
+everardo molina No more balloons for my highschool graduation party?!?!
Hey ur in grade 10 now lol 11 next yr
Man, Hank really cleaned up since these videos.
this has hands down the greatest thumbnail of any scishow episode.
Just an update, we are in 2022 and still have a lot of helium left 1:58 😁
whew
OK so it’s 2021. Can we get a follow up video on how we have conserved helium?
damn havent heard of that helium shortage yet!
I found the easter-egg!

I read a story on Taylor in Popular Science. Pretty amazing young man. Absolutely brilliant.
i came here because i thought it would be hilarious to hear hank with a squeaky voice...
i was overwhelmingly satisfied
We need an update on our reserve supply and outlook now that we're in to the dreaded aforementioned 2020! 😱
I take it back. Now after the 2020 we're already having, I don't think I really want that update anymore.
I'm going to be honest here, if Hank had that voice all the time, I wouldn't stay subscribed.
2021 we still got heliim :D... For now..
This is the kind of guy that would tell you the world is ending in the same tone of voice as he would tell you he forgot to flush the toilet
can you do a video on the big bang and inflation theorys :)
This is an oldy, but is a goodie. I vote up for a remake!
I read an article in a magazine about that kid. I think it was about him making some crazy furnace ( for lack of the right word, maybe arc reactor? ) that could make plasma.

Also, you SHOULD do a whole episode on that guy, cos he is awesome, and I want to know more than what I read in this one magazine .___.
I've never inhaled helium, and then listened to how my voice sounds. Maybe I should have that experience before it's too late.
when he inhales the helium at the end he sounds like Steve Buscemi lol
Dang 2020 is right around the corner
ALSO DID WE RUN OUT OF IT YET?
OMR! Hank's Helium voice! I am actually crying with laughter!
Damn you sound great with helium.
The beginning of this video reminded me of Fred for the first time in years and years.
awesome, thank you!
So it’s 2020 we still have helium?
It's now near the end of 2020
Sound travels really fast in helium, something about 1000 m/s. So, if you look at the waves equation, you'll see that the higher the velocity, the higher the frequency must be.
The air in your vocal chords gets lighter in your vocal chords, making your voice go faster, which makes it sound higher. I think.
On helium you sound like the guy in the middle of the galaxy in Spore. Don't remember his name, but he was amazing.
Hank, can you do an episode explaining how LEDs work? And perhaps how LCDs work? And why they both make awesome TV screens?
Can you make a video about neon? (Its my favorite noble gas)
1:11 There is a short time where "V.O. full screen gfx" is displayed in the middle of the screen.
Soooo....did we run out yet?
Um, could you do a video on Taylor Wilson...he's kind of been my hero since I was in third grade and read an article about how he achieved fusion...
The speed of sound is higher in helium than in normal mixtures of gas in air. Because of this, whenever you speak with a lung full of helium, your voice projects at a higher frequency than normal.

At least he said "I shouldn't be wasting this, but.."
1:58 wait hank said we’ll run out of helium by 2020. It’s 2020 now and I can still get helium.
