Ro: Hey guys, welcome to another Nerdy Nummies! Today I have my friend
Ro: Travis from NexGen, I’ll put his link below so you can go check it out.
Ro: He is a world record over-clocker, which is basically making computers
Ro: run really, really fast. Travis: Absolutely, it’s trying to make the
Travis: computer run as fast as possible so you can run the game at the highest
Travis: settings with the most frame rates.
Ro: Which is amazing, that they use liquid nitrogen to do this.
Ro: To make your computer work super, super fast.
Ro: Let’s start with the facts about liquid nitrogen. It is super, super cold.
Travis: Absolutely, liquid nitrogen is 320 degrees below zero, therefore it is
Travis: extremely cold! And uh, in its state while it’s a liquid, um, it does
Travis: get absorbed into clothing and it can cause burns if it sits on
Travis: the skin too long, so what we are gonna do is we’re gonna wear safety
Travis: glasses. Ro: Yeah, safety! Travis: And we’re gonna have our gloves.
Travis: That way we’re protected, and uh, while handling liquid nitrogen you always
Travis: want to be careful that you’re not splashing it around.
Travis: In the event that liquid nitrogen does come in contact with your skin,
Travis: there’s the leidenfrost effect, which will actually prevent the liquid
Travis: nitrogen from coming in direct contact, so it will bead up and simply
Travis: roll off the surface of your skin. So long as your hand is dry and you
Travis: aren’t making a cup to try and capture the liquid inside. You would
Travis: see that after it comes in contact with the skin for a prolonged
Travis: amount of time it will start to cause frost burn.
Ro: So you can actually stick your hand in liquid nitrogen and pull it out,
Ro: but not hold it in there. Travis: Absolutely, if it’s something quick,
Travis: it’s kind of like a game of hot potato, you know you can splash it
Travis: on there a little bit and it’s just going to simply roll off, you can
Travis: even kind of play around with it. And see how it just kind of beads
Travis: up and moves around across the surface of the table.
Ro: Today we’re gonna be making strawberry vanilla ice cream with
Ro: liquid nitrogen! Let’s get started!
Ro: What you’ll need is: 2 cups of strawberries, chopped up, 2 tablespoons of
Ro: vanilla, 1-1/2 cups of half and half, 4 cups of heavy cream,
Ro: 2 cups of sugar, and measuring spoons!
Travis: You’ll also need 1 larger stainless steel mixing bowl, 1 stainless
Travis: steel wire whisk, and plenty of liquid nitrogen!
Ro: We’re gonna mix all the ingredients together, and then slowly pour in
Ro: all the liquid nitrogen. And then, a cup and a half of half and half.
Ro: And 4 cups of heavy whipping cream. We did the math, we knew we had enough.
Ro: And a couple tablespoons of vanilla extract, you can add as much as you
Ro: want. It depends how vanilla-y you want your ice cream to taste!
Ro: I want it to taste very vanilla-y! There we go!
Ro: Travis, you have actually made this, so what do we do next?
Travis: Well, you’re gonna want to mix everything together and try to get it all
Travis: dissolved before we put the liquid nitrogen in, because we want
Travis: to have that ice cream consistency. Ro: OK, so I take this whisk
Ro: and just mix it together, kind of like cake batter! When you’re mixing
Ro: everything together? Travis: Absolutely. Ro: OK, I’ve never made ice cream
Ro: before, this is my first time.
Travis: You’ll find that with liquid nitrogen it’ll be the easiest way to
Travis: make ice cream. Ro: Is it? Travis: Well, typically when you make
Travis: ice cream, it’s a process that lasts several hours, with the liquid
Travis: nitrogen, we’re gonna speed that process up, we’ll do it in a matter
Travis: of seconds to minutes. Ro: Hmmm. Travis: When we use liquid nitrogen
Travis: it’s actually gonna freeze so fast that the crystalline structure
Travis: will be very, very, very small, meaning that the ice cream will be
Travis: extremely smooth and very delicious!
Travis: Go ahead and add those strawberries now. Ro: OK!
Ro: I went a little crazy, I don’t know if this is 2 cups of strawberries,
Ro: I just cut up so many of them.
Ro: And, that’s probably better… There you go, get in there!
Ro: Yummy! Travis: As long as there isn’t anything still at the bottom, like
Travis: maybe some residual sugar. Ro: Mmmhmm. Travis: And you’ve got your
Travis: ingredients, like the strawberries, mixed in properly, then you can
Travis: start to add the liquid nitrogen. Ro: OK.
Travis: I’ll be doing the mixing. Ro: Yeah. Travis: So I will give you the
Travis: honor of pouring the liquid nitrogen. Ro: I like this idea!
Ro: This is a good idea, because he’s gonna man-muscle it, while I just get
Ro: to pour the cool stuff!
Ro: Alright, I’ll slowly pour it, so just tell me when, OK?
Travis: Just start to slowly pour it in there, and as we see how much
Travis: it starts to stick together and freeze, you can start to add more.
Travis: So go ahead and continue to give a slow pour. Ro: Ah it looks so cool!
Ro: A-bubble, bubble, toil and trouble!
Travis: And you’ll start to see it bubble up quite a bit here.
Ro: So when it’s bubbling, what is that doing? It’s like boiling, but it’s
Ro: boiling cold? Travis: Yes, absolutely, the liquid nitrogen itself is
Travis: boiling inside of the ice cream mix, and as it boils it will create that
Travis: nitrogen gas that you see escaping. So it’s gonna kind of foam up
Travis: the ice cream. And we can go ahead and continue to add that liquid nitrogen
Travis: as we stir, and it’s becoming a little bit heavy
Travis: as I try to mix this up. Ro: This looks awesome!
Travis: It’s definitely forming into ice cream right about now!
Ro: Yes! Stand back, I’m doing science!
Ro: Whoa, look at that! Amazing! The bowl feels frosty!
Travis: We’ve got it frozen, it is, officially ice cream!
Ro: Woo-hoo! It is ready to eat, check this out!
Ro: We made vanilla ice cream with strawberries! Yum-yum-yum-yum-yum!
Ro: It is ready to eat!
Ro: Can I touch it? Travis: Oh yeah, mmmm! How’s that taste?
Ro: Oh my gosh, it’s actually really good! Oh my gosh!
Ro: Maybe a little bit too much vanilla, but…
Travis: It’s triple vanilla, remember?
Ro: Got this cute little scoop, dee-dee! I’m gonna scoop ‘em up, and it’s
Ro: ready to eat! Rewp!
Ro: I’m gonna have to… Oh there we go!
Ro: Oh! It’s so cute!
Ro: Da-da! All done! Thanks you guys for watching this episode of Nerdy Nummies!
Ro: And thank you Travis for being here, this was a lot of fun.
Travis: Thank you for having me on, it has been an enormous amount of fun!
Ro: Yeah, I have never played with liquid nitrogen before, or made ice cream,
Ro: so this was a first. We did good!
Ro: If you guys have any other suggestions for any other Nerdy Nummies, please
Ro: let me know, leave me a comment below and I will do my best to make it
Ro: happen! OK, oop! Bye-bye!
