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!

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.

well kids like watching a flower break, and adults love knowing how the flower breaks while watching it

GREAT WORK AMAZING TEACHER!!!

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

yet another good teacher

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

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.

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.

This was amazing, ty Jefferson Lab.

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.

one of the most amazing Open houses I've ever watched.

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!

@1joezy They are at Jefferson Lab in Newport News, Virginia. More information can be found by following the link in the video description.

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.

@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.

Classic liquid nitrogen experiments... I love this kind of stuff!

i love his energy in all his experiments

I'm in love with these videos

Great opening demonstration

I wish I had an amazing teacher like this man ☺️

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.

this is just beautiful

excellent presentation! thank you.

so nice to just chill and feel like I'm in class with this dude.

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. :)

This was a nice blast to the past.

Loved it!!

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

Thanks for sharing!!

It brings me back and I hope my kids gets to learn from this guy one day. Awesome Jefferson.

Enjoyed it ! Danke !

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.

Great presentation for all ages.

@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.

@1EminemLyrics Because they work as effective demos.

@danpatchlinerailfan It's stored in insulated containers called Dewars. You can see two of them in use in the video.

excellent show!! I'm 21 years old and I enjoyed this!!

You guys at Jefferson Labs are great! For the first time, a popular video channel actually responds to comments!

@pulseforce Thank you!

Thanks!

Very basic but a great explanation, I really enjoed ur passion and the visors enjoying it, well done.

In the end, I would have shaken the guy's hands thanking him a hundred times for making physics exciting again.

@JeffersonLab Thanks! :-)

@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.

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

This is just amazing! love it xD

@Almontmarine A number of the 'Joanna and Steve' videos are reworked segments taken from our standard liquid nitrogen show.

@DYLONayms It's a presentation for a general audience, not a class.

i've always enjoyed these kinds of things. good performance.

Wow so good!!

such a great teacher

This guy would make a great high school science teacher

@softwhere07 Thanks! They're fun to do!

Hello from a grad student in WI! Boy, this takes me back. Shows like this made me the scientist I am today.

@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.

Science is AWESOME!!!!!!!

@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.

Thanks for the reply Keep up the awesome work! really enjoy watching your videos :D

Looks like a magic show

Thankyou!

We do, but the application for summer interns was back in February. Maybe next year!

Awesome man!

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.

I love that poping sound

i love your videos ty for the videos

@thescotishawesome Jefferson Lab, Newport News, Virginia.

How does what shrink? The balloon?

@JeffersonLab I completely agree :)

that made me smile :)

I like this kind of video

This was highly enjoyable(:

they are most greatest teachers

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.

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.

Newport News, VA. Additional information can be found via Google.

If you're in the area, you can come to the one we're having on Saturday, May 19th.

00:05 gave me the feeling of fun with flags intro from big bang theory

air can freez wow never new that u learn something newevery day (:

@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.

Nice video and show. You are amazing! :) I've subscribed to your videos. I have never touched Liquid nitrogen but it sure looks amazing to play with. :)

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!

Sigh, I wish you two were around when I was in grade school, you're way more interesting then some teachers I had.

Very interesing article. Thanks :)

Could you post a video showing of all of it's awesome properties

@ilikepienotu Yes. That's actually why we have the liquid nitrogen in the first place.

which is the best conducter material at normal temperature, I had that qwestion because would be better to use it on the voice coil of a speaker insted of copper or aluminum, a better conducter would make a bigger magnetic field to make the speaker more efficient? or the inverse of that, also te voice coil of the speaker makes a lot of heat cooling the magnet and the coil of the speaker would afect the eficiency of the speaker? bass speakers arent realy eficiet so could you make it better?

now that's good content

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/

@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.

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.

very cool

I think I am becoming addicted to watching videos on youtube that are posted up by the Jefferson Lab.

This guy needs his own show.

Great host!
