I know people say this is kids stuff, but I'm 35 and still enjoy watching it. Besides, this "kids stuff" is a good way to find those kids that find it fascinating and introduce them to what could very well end up being their future.
The Open House is held every two years, funding allowing, typically in the Spring. The date of the next one would be announced on our Facebook page and Twitter feed, as well as other outlets.
@liklikchui Because the tank is well insulated, whether or not the lid is on it. Removing the lid only allows a small amount of additional heat to enter the tank. It's sort of like opening a window in your house a crack in the summer. A little heat comes in, but it's not as if your whole house suddenly becomes the same temperature as the outside.
For general use? We get liquid nitrogen from a storage Dewar located at the Test Lab. The Lab gets it from an outside vendor. I believe that Air Liquide holds the current supply contract.
This man is a gifted teacher! If all the people involved in America’s educational system had half of the obvious passion that this man has then perhaps people would stop making fun of us. In the seventh grade I only passed two classes, and both of those classes where taught by passionate teachers just like this guy. Because of those two teachers who went that extra mile, I got a taste of success, and it changed me forever. We need more people like this, the world would be different!
It depends on the amount of nitrogen. The initial bits would rapidly change to a gas due to the hand's warmth. But, doing this isn't a free process. The hand looses some thermal energy as the nitrogen boils off. If it's a small amount, that's about all that happens. No real harm is done, much like throwing an ice cube in a swimming pool. If enough nitrogen is used, or if the liquid gets trapped against the skin, portions of the hand would freeze.
@TheTrippleZero It depends on the amount poured. The first bits of nitrogen will boil away but, given more nitrogen, it will eventually freeze your arm.
Just visited the website. I didn't realize just how big Jefferson Lab facilities were. Loved the show. I'm going to make every effort to be there for the next open house.
I liked this video and seeing how you interact with a live crowd. I've seen all of these before, but I like the way you showed the liquid inside the balloon. Also, one fun version of the balloons in LN2 is to use balloon animals [it works for some nice jokes about putting animals in LN2]- I've learned to tie balloon animals just for this purpose.
@LoveClassicMusic0205 The non-shiny cup is the one that gets smooshed. It's really out-of-round. That's why it doesn't ring as well as the shiny one, which is nice and circular.
@meowmeow5 In fairness, he wasn't actually tasked to film any of the cryo shows. We was going around the Lab getting footage for the Open House video we were planning. The only window for filming the segments with Joanna and Steve was immediately after this show. Technically, he was 20 minutes early for that filming.
You don't. There are some materials that become superconductors at temperatures warmer than that of boiling liquid nitrogen, but the liquid nitrogen isn't part of the superconductor. Anything that gets it cold enough will allow the superconductivity to happen, whether liquid nitrogen, liquid helium or something else is used. Liquid nitrogen is relatively inexpensive, so it's convenient to use.
@dkornsb I'm afraid I'm not understanding what you're asking. I've never heard of the earth referred to as an oxygen planet. I have heard it referred to as a water planet, though.
@meowmeow5 It's not that the camera wasn't allowed to film the whole thing. When the camera walked into the room, this particular show was already half over.
i just discovered this channel and im hooked this teacher is simply amazing!! he makes it easy to understand all while making it entertaining. great teacher!
@goopstir Jefferson Lab's Open House is held at Jefferson Lab in Newport News, Virginia. The Open House is free. Visit the website referenced in the video for information about our next Open House, as it becomes available.
For anyone curious this isn't at a school. It's an open house presentation done at the Jefferson Lab in Southeastern Virginia which is free and open to the public. Here's the link for when the next show is: www.jlab.org/openhouse/
Specifically? I'm not certain. I believe our Dewars have a relatively high nickel content. Part of the reason why the Titanic sank was that its steel became brittle in the cold waters of the North Atlantic. Don't know its composition was, though.
@roadcrosser Our superconducting accelerator requires liquid helium and liquid nitrogen is used to cool helium to 77 K before sending it to compressors to get cooled the rest of the way. That accounts for most of the 6,000 gallons used in a day. One of Steve's shows uses about one gallon of nitrogen. It's not a major contributer to our use of nitrogen.
Ahh, I forgot about stuff like that. The show i went to, was meant for an older audience, so that might be why. Anyways, your videos are very entertaining. Thanks for putting them up!
it shrinks because all the air turns into liquid and the balloon needs air to be inflated but since the balloon is short in air it starts to shrink. the more the air turns into liquid the more the baloon gets deflated.
This was great, guys! I'm 22 years old, but I was glued to the screen the whole time. What a great guy to have a show like this! :)
The best act that a teacher can produce is to entertain but also to inform, to educate, and to inspire. I'm glad that this guy can do all four!
Hi future you. You are now 26
I'm 22 now!
31 old broo
Why cant i ever have a teacher as enthusiastic as this guy
I asked myself the same question the whole video
Am I the only one who never wanted this to end? :(
same bro me too
Nope.
yep
no
yeah
You Sir... Have gained immense respect from my side in just matter of 19 mins.
From a chemical engineer.
Keep up the great work.
Same here
I know people say this is kids stuff, but I'm 35 and still enjoy watching it. Besides, this "kids stuff" is a good way to find those kids that find it fascinating and introduce them to what could very well end up being their future.
Damian Wezzterman Spot On!......I'm 39 and am enjoying it. Nobody's ever too old to learn.
I agree, this is extremely interesting
well kids like watching a flower break, and adults love knowing how the flower breaks while watching it
GREAT WORK AMAZING TEACHER!!!

yet another good teacher
If only I had a teacher like this when I was in school, I would have loved chemistry class!

Normally from the Test Lab fill station. Currently, though, we're getting it from the CTF due to construction relating to the Test Lab renovation.

This was amazing, ty Jefferson Lab.
one of the most amazing Open
houses I've ever watched.
@1EminemLyrics Because they work as effective demos.
Hello from a grad student in WI! Boy, this takes me back. Shows like this made me the scientist I am today.

If you're in the area, you can come to the one we're having on Saturday, May 19th.
In the end, I would have shaken the guy's hands thanking him a hundred times for making physics exciting again.
Classic liquid nitrogen experiments... I love this kind of stuff!
science is so cool haha. these videos make me remember how much I used to enjoy high school chemistry with all the demos and experiments
You guys at Jefferson Labs are great! For the first time, a popular video channel actually responds to comments!
You can apply for a job through the Lab's website. The pay would depend on a number of factors.
@spartan119ify This was at Jefferson Lab's Open House back in 2010. Jefferson Lab is located in Newport News, Virginia, USA.
@DYLONayms It's a presentation for a general audience, not a class.
I wish I had an amazing teacher like this man ☺️
3:32
“What froze?”
“The flower”
“What in the flower?”
“ThE AtOMs!”
LMAO
It's 2:13 am and that type of night where you click on random videos and go from a fortnite highlights video to a chemistry channel.
We do, but the application for summer interns was back in February. Maybe next year!
I like this kind of video
Just visited the website. I didn't realize just how big Jefferson Lab facilities were. Loved the show. I'm going to make every effort to be there for the next open house.
@pulseforce Thank you!
@danpatchlinerailfan It's stored in insulated containers called Dewars. You can see two of them in use in the video.
i love his energy in all his experiments
@ilikepienotu Yes. That's actually why we have the liquid nitrogen in the first place.
This was a nice blast to the past.
You're a great teacher. You make it fun for for the kids. I just wish all teachers had your energy and enthusiasm. Good videos, thanks.
so nice to just chill and feel like I'm in class with this dude.
@Almontmarine A number of the 'Joanna and Steve' videos are reworked segments taken from our standard liquid nitrogen show.
Thanks!
It brings me back and I hope my kids gets to learn from this guy one day. Awesome Jefferson.
@softwhere07 Thanks! They're fun to do!
@1joezy They are at Jefferson Lab in Newport News, Virginia. More information can be found by following the link in the video description.

That's what the 'initial bits would rapidly change to a gas due to the hand's warmth' part is about.

Very basic but a great explanation, I really enjoed ur passion and the visors enjoying it, well done.
I think I am becoming addicted to watching videos on youtube that are posted up by the Jefferson Lab.
Thank you for uploading this and for this for the general public. I think it's really amazing what you do and I really enjoyed watching it. :)
Assuming that you have the training and equipment to safety transport, store and use it, try contacting a local welding supply shop.
i just discovered this channel and im hooked this teacher is simply amazing!! he makes it easy to understand all while making it entertaining. great teacher!

12:55 the waitress whenever you sip your drink
That's so cool with the balloon end in the liquid nitrogen. I'm surprised it was not frozen, and wouldn't be able to inflate.
00:05 gave me the feeling of fun with flags intro from big bang theory
this is just beautiful
Science is AWESOME!!!!!!!
excellent presentation! thank you.
The baloon looks like when we crush the chocolate paper,keep it on a table and its retaking its shape
such a great teacher
@dkornsb Yeah, we inhale nitrogen all the time. It makes up 78% of the air after all...
Do a search for 'Jefferson Lab Physics Fest'.
i've always enjoyed these kinds of things. good performance.
If this was actually my teacher, maybe I would've paid attention and actually listened, instead of trying to study by myself
How does what shrink? The balloon?
Looks like a magic show
Sigh, I wish you two were around when I was in grade school, you're way more interesting then some teachers I had.
A teacher like him can make people love science
Thanks for sharing!!
It depends on the steel.
I love that poping sound
@JeffersonLab Thanks! :-)
This guy needs his own show.
That mom chuckling at 6:17 got the joke!
Newport News, Virginia.
Ahh, I forgot about stuff like that. The show i went to, was meant for an older audience, so that might be why. Anyways, your videos are very entertaining. Thanks for putting them up!
Enjoyed it ! Danke !
Nokkia 3310 VS LIQUID NITROGEN. WILL IT BRAKE?
+Nedas Ltu No, It wouldn't break either
Will nitrogen survive?
I'm watching this 8 years later at 1.27am and this is pretty interesting
@thescotishawesome Jefferson Lab, Newport News, Virginia.
air can freez wow never new that u learn something newevery day (:
it shrinks because all the air turns into liquid and the balloon needs air to be inflated but since the balloon is short in air it starts to shrink. the more the air turns into liquid the more the baloon gets deflated.
Could you post a video showing of all of it's awesome properties
Modern pewter doesn't contain lead. At least, it isn't suppose to.
