RUBEN MEERMAN: Yeah!
ELLIOT SPENCER: Yeah! What are we doing? I'm hungry.
RUBEN MEERMAN: We're gonna do some un-cooking.
ELLIOT SPENCER: Un-cooking.
RUBEN MEERMAN: Un-cooking.
ELLIOT SPENCER: Is it possible?
RUBEN MEERMAN: Course it is. With liquid nitrogen, anything's possible. Now we've learned some amazing stuff about liquid nitrogen. We know that it's minus…
ELLIOT SPENCER: 196 degrees Celsius.
RUBEN MEERMAN: Right, so we're gonna use liquid nitrogen now to see what happens to some stuff that you're already familiar with, like a lettuce, like some marshmallows.
ELLIOT SPENCER: Are we going to make sang choy bow?
RUBEN MEERMAN: Ah, maybe. We're going to see what happens to a banana. So I'll just put that there for a little while, and let everyone marvel at it while I get ready a lettuce leaf.
ELLIOT SPENCER: Ooh.
RUBEN MEERMAN: Now normally when you cook foods, you heat them up, and that makes them softer and yummier, and easier to digest. But let's see what happens to this ordinary piece of lettuce. Let's just put it in there and I'll get my tongs. Ding, ding, ding.
ELLIOT SPENCER: Is it ready?
RUBEN MEERMAN: I think so.
ELLIOT SPENCER: I'll have one piece of brittle lettuce, please.
RUBEN MEERMAN: OK, here it comes. Oh, no, already smashed it! Look at this. It sounds like glass! It's amazing!
ELLIOT SPENCER: Can I touch it?
RUBEN MEERMAN: Yes, of course you can touch it! Listen to it. Sounds like… Eugh!
ELLIOT SPENCER: Oh! Let's cook some marshmallows. These are so soft and cuddly.
RUBEN MEERMAN: Yeah, yeah. They're lovely. So we'll put that there. And you can see that if you tap it, nothing really happens to it. We'll put it into the liquid nitrogen. And we're uncooking it.
ELLIOT SPENCER: Yep. Just imagine that I'm by the campfire. Ruben, you got any more of those beans?
RUBEN MEERMAN: Yeah, yeah. OK. Wah!
ELLIOT SPENCER: Oh! Chop-a-roony!
RUBEN MEERMAN: Look, it smashes into pieces! Yeah, let's do another one. Karate-chop it. You wanna karate-chop this one?
ELLIOT SPENCER: Yeah, I do.
RUBEN MEERMAN: Hang on. I wanna make sure it's really cold.
ELLIOT SPENCER: Hi-ya!
RUBEN MEERMAN: Look, it smashes into little pieces. And you can still eat that. Give it a little blow. And then pop it in your mouth.
ELLIOT SPENCER: Oh.
RUBEN MEERMAN: Delicious?
ELLIOT SPENCER: Slimy. Really slimy.
RUBEN MEERMAN: Ha-ha!
RUBEN MEERMAN: Banana is a pretty solid sort of a fruit, right? And it's also mainly water. If we pop this in here and let it uncook for a little while… Might put this down on the table. Could you remove the black bucket please, Elliot? OK, because underneath here, I don't know if you noticed, but I have a piece of wood. And in this hand, I have some nails.
ELLIOT SPENCER: Yep.
RUBEN MEERMAN: No hammer.
ELLIOT SPENCER: What're you gonna do here?
RUBEN MEERMAN: Well, check it out.
ELLIOT SPENCER: What're you gonna do? What?
RUBEN MEERMAN: Stop. Hammer time.
BOTH: (Hum U Can't Touch This by MC Hammer)
RUBEN MEERMAN: You can't touch this.
ELLIOT SPENCER: Oh. (Laughs) That is awesome.
RUBEN MEERMAN: Yeah! Not everyone makes this at home, but I'm gonna make some ice-cream. Elliot, there's some cream there. Could you please pour it into that container?
ELLIOT SPENCER: I might take my gloves off.
RUBEN MEERMAN: Yeah, go for your life. Alright, 600mL of milk. Next one is 600mL of cream, please.
ELLIOT SPENCER: Cream. Pour that in too?
RUBEN MEERMAN: Yes, please.
ELLIOT SPENCER: OK.
RUBEN MEERMAN: Beautiful. Elliot, there's a cup of sugar over there, please. Could you sieve that into that mixture?
ELLIOT SPENCER: OK, where's a spoon?
RUBEN MEERMAN: OK, here's a spoon for you to help get it through. There you go. There you go, yeah. He's not the most experienced chef in the world. Very good, now can you please start stirring that mixture for me?
ELLIOT SPENCER: I'll stir it.
RUBEN MEERMAN: The fourth ingredient in ice-cream, a little bit of vanilla essence. So let's put in about a tablespoon of that stuff there. OK, there you go. Alright. Now we're going to freeze that mixture using liquid nitrogen. Time to uncook it. Ready?
ELLIOT SPENCER: Alright. Yep.
RUBEN MEERMAN: You might wanna put some gloves on so I don't splash it on your hands.
ELLIOT SPENCER: Mm-hmm.
RUBEN MEERMAN: OK, okey-dokey. I'm gonna start pouring it in. Let's see how quickly we can make ice-cream. Here it goes.
ELLIOT SPENCER: Start going?
RUBEN MEERMAN: Yeah, start stirring it up. In your freezer at home, it takes ages to make ice cream. Yeah, not…
ELLIOT SPENCER: Not too fast.
RUBEN MEERMAN: Yeah, not too fast. Just try and have a look and see what you're doing there.
ELLIOT SPENCER: I can't! There's a cloud of fog.
RUBEN MEERMAN: (Impersonates Swedish Chef from The Muppets) Keep your fork still now, because I want you to taste this delicious ice-cream.
ELLIOT SPENCER: (Laughs)
RUBEN MEERMAN: Look at that. Not fair at all. Elliot, tell me, how does that taste? Not bad.
ELLIOT SPENCER: Very vanilla-y. Mmm!
RUBEN MEERMAN: You like it?
ELLIOT SPENCER: Mmm, but you probably don't believe me. They'll say anything on TV. Which is why we have to call up Rollercoaster's official food taster, please welcome Ellen! Come in the middle, Ellen.
RUBEN MEERMAN: Hello, Ellen! Now, Ellen, I'm going to prepare you an ice-cream. Here we go.
ELLIOT SPENCER: Oooh.
RUBEN MEERMAN: (Hums Greensleeves)
ELLIOT SPENCER: You've got a little bit of dribble coming out there. Alright, here we go. I want you to tell me how many mmm's you give it.
ELLEN: 4.5 mmm's out of 5.
ELLIOT SPENCER: Yeah!
RUBEN MEERMAN: Yeah! 4.5! Woo! A boiling kettle. Freezing-cold liquid nitrogen. One, two, three!
ELLIOT SPENCER: Whoa!
CHILDREN: Whoa!
ELLIOT SPENCER: Oh, rumble in the jungle!
RUBEN MEERMAN: Rumble in the jungle! More!
ELLIOT SPENCER: Whoa! More!
RUBEN MEERMAN: It's pretty amazing, isn't it? I don't think anyone's winning. I think they're combining to make a very spectacular cloud. The liquid nitrogen's evaporating away and becoming a gas again, but I reckon that's a tie.
ELLIOT SPENCER: There's no clear winner.
RUBEN MEERMAN: No, they're friends.
ELLIOT SPENCER: Yes! Of course, and that's the way it should be. You know what I've learned?
RUBEN MEERMAN: What have you learned?
ELLIOT SPENCER: If you're building a house for monkeys, use banana hammers.
