字幕表 動画を再生する 英語字幕をプリント Hey, I'm Dianna. You're watching Physics Girl. I have just received a package. A mystery package from Rosanna Pansino, who's another YouTube creator. She did a moon landing cake. So, she's a cool girl, yeah. So, here we go. "You've been selected to participate, "in the Great Gift Exchange." Cool, um, and then there's a URL. Very mysterious... [HUMS] go. Hey, y'all I'm Alton DuLaney. The world's most famous gift wrap artist and YouTube's Wrapresentative Giftlomat Presenter. That's a great pun. You have been selected to be a part of YouTube's Great Gift Exchange. Where you and 11 other creators will participate in a chain of charitable gift giving. And, as a gift, each of you will make a donation to a charity that is important to your recipient. Then you'll be whisked away, to my whimsical wrap shop where I'll teach you how to gift wrap the creator's donation... Oh, cool. ...in a thoughtful way. Now, you're probably curious about what's inside your present. Go open that dang thing. A pie cutter with an, "I love Pie" on it, but, specifically, Pi, the symbol. Like, 3.14. I love Pi, which is true, both counts. [GASPS] Oh, my gosh. This is so cool! It's like a bunch of pie. "Insert rhubarbitrary pun here." I love that. So clearly Rosanna knows that I love puns, and specifically puns of fruit. Because I interviewed a lot of fruit during the lockdown. "Wishing you a very cherry holiday." "You're a great creator and that's no lime." "Turn this potential energy into, "pumpkinetic energy." [LAUGHS] Oh, it's too good. "To open me, give me apple." Give me a... give me a pull? Give me a pull. Oh, it's a little box. Oh, that's so cute. Oh, my goodness. This is so cool. All right, here we go. "Rosanna Pansino has made a charitable donation "to the Malala Fund in your name." That is amazing. The Malala Fund does incredible work for girls' education. This is awesome. Clearly, Rosanna has done her research. She knows that puns are the... "kiwi" to my heart. Okay, let's check back with the rest of that video. And now, without further ado. Aah! I took years of modern dance. Let's find out who your lucky giftcipient is. [AMUSING INSTRUMENTAL MUSIC] -What! -[BOX THUDS] Oh, come on! -[MUSIC STOPS] -Physics Girl, your official giftcipient is... The awesome Alex Wassabi. Cool... Yes, I... love this so much. Alex is a really fun creator. I'm so excited. I get to learn how to wrap like this? See you at the wrap shop. Oh, my voice! [CLEARS THROAT] See you at the wrap shop and enjoy the train ride. I think he and I are gonna make a great "pear"! Okay, that is enough fruit puns. [TRAIN WHISTLE BLOWING] [TRAIN HORN TOOTING] If I left San Diego about two hours ago. I shouldn't have gotten to where there's snow so soon. NARRATOR: And so Dianna rode on our wintry train, Huh, this actually makes no sense. NARRATOR: to wrap with Alton, and her physics brain. [GASPS] It's holiday magic. -Speaking of magic, what's that I hear? -[TRAIN HORN TOOTING] That must be Physics Girl now. I'm so excited to work with Dianna Cowern today. From a young age, she was very interested, in science communication and about making science accessible to everyone, especially, young women, who really look up to her. [DOOR OPENS, CLOSES] Well, hello, Dianna, and welcome to the wrap shop. This is amazing, thank you. I'm excited to do some gift wrapping with you. I've heard much about you. Well, I've heard a few things about you, too. Is it true that we are just stardust, at the end of the day? We are. We are all made of these exploded stars, that in the long, long distant past turned into all these elements that make up us. Speaking of explosives, I think my mind has been blown, -[DIANNA LAUGHS] -just, thinking about that. -Already... -Did you grow up, in a family where gift wrapping was a big part of the holidays? Oh, absolutely. I grew up in Hawaii. -Great, fun. -So, we didn't have, like, the white Christmas or anything. I was such a nerd, and I loved math and I would just fold everything -so precisely. So, I was always like, -Oh. making these... the lines and the creases. -She and I are gonna get along just fine. -[LAUGHS] Well, Alton, I have a question for you, world's most famous gift wrap artist, do you have a piece of paper? -Do I have a piece of paper? -[CHUCKLES] [LAUGHS] Where were you hiding that? How many times do you think you can fold this paper in half? I could fold this paper all day long. -All day long? -Yeah, once, twice. ALTON: Three times, four. DIANNA: Mm-hmm, four. That was four times. -Five, six. -Six. -Maybe seven. -Seven. He's getting off his shoe. -[BOTH LAUGHING] -DIANNA: Interesting. There's sort of an urban legend that folding a piece of paper, more than seven times in half is impossible, but that's not completely true. I have a feeling I'm not gonna be the only one doing teaching here today. There's a girl Britney Gallivan who's a high school student, really, really smart girl. She came up with an equation, to determine how long a piece of paper would need to be, and how thick it would need to be in order to fold it, "n" times. Like, any number of times. I know an equation just appeared on screen, but don't be scared, I love the math. "L", your length, equals "pi" times "t", your thickness, over six, times two to the "n" plus four times two to the "n" minus one. So cool! Using this equation, Britney managed to fold a piece of paper in half twelve times. But it started at 4,000 feet, -Oh, my gosh. -long. DIANNA: And it was the thickness of a sheet of toilet paper. -That must have been one big roll of toilet paper. -[LAUGHS] But there really are some hard limits to this. If you fold a piece of paper in half more than 300 times, you'll end up with a book with more pages, than there are atoms in the universe. -So... [LAUGHS] -[EXPLOSION SOUND] that would be hard to fit in your backpack. Wow, I promise you, Dianna, today we're not gonna fold any, -wrapping paper more than seven times. -Okay. So, I know that your gift recipient is Alex Wassabi. Tell me what you know about Alex. As a scientist, I have done some research. So, here's little bit about Alex. Alex Wassabi is a YouTuber. He's an incredibly positive person. His motto is actually, "If you're not smiling, you're doing it wrong." I love this. We're always smiling here at the wrap shop. He likes to do vlogs and challenges, he just has a really fun channel and fun energy about him. Alex is a big supporter of the Make-A-Wish Foundation, and so, I'm giving a donation to the Make-A-Wish Foundation in his name. -Ah, such a great gift. -Yeah, and also, for fun, I got a small little gift for Alex and his brothers, because they're really big on family. And I love that, so it's something for him to keep and it's something, the charitable donation, that's something that goes above and beyond. Really cool. Well, if you're ready. I was thinking we could head over to my gift wrap laboratory and do a little experimenting with gift wrap. Yes! I'm so ready. Now, I know you live in a scientific world but, here at the wrap shop, I like to have a little holiday magic. -So, if you would snap with me on a count of three... -Mm-hmm. -One, two, three. -[BOTH SNAP FINGERS] ALTON: We disappear. Welcome to my laboratory. This is amazing. So, I thought today we would start out by wrapping the thing that every young scientist would love to get for the holidays, the science kit. Science kit! So many activities in here, so much learning. Today, we'll be using the Japanese art of Foroshiki, which is wrapping with fabric. We'll be incorporating a common scientific fashion accessory, the lab coat. How are you at folding laundry? -I'm more like a [WHOOSHES] roll-up kind of girl. -[BOTH LAUGH] We're gonna start with the lab coat. We're gonna slide this over as if we're dressing our lab kit. And now, here's my new lab assistant. So, Dianna, tell me. What are we cooking up in the lab today? I think some presents. [WHOOPING] My favorite. And now what we're gonna do with the back of this, we're gonna fold it in just a bit. DIANNA: Then you'll tape it on? ALTON: Yeah, I'm just gonna tape that down 'cause the front of this is really gonna be the star of the show. -We're gonna flip that baby over. -All right. ALTON: And now, we're gonna take the sleeves. And we're gonna tie them in the middle. into a little knot as if this were our bow. Oh, cute. It's already nicer than any gift I've ever wrapped. ALTON: I'm gonna slide the goggles down and around over this. Just gonna fit around there. -Yeah. -It needs a little stretching. DIANNA: Oh, that's very cute. And now, we're gonna add one more little flourish. We're gonna add a little paper pocket square. -Is mine too thin? -Yours is actually better than mine. -ALTON: So just fold-up over there, yeah. -Fold it over? And now you're gonna repeat that over and over. DIANNA: Over and over. ALTON: Over and over. Excellent. See, you're true to form. -You're creasing between each wind. -DIANNA: Uh-huh. ALTON: I love that. DIANNA: [LAUGHS] So, now we're going to create a fan fold. -Grab the ridges of that pleat. -Mmm. ALTON: You're gonna pull it stronger with one hand than the others. Oh, my gosh. There's immediately so much geometry going on here. -Yeah, what is my angle there? -I'm up to 45. DIANNA: Ta-da! -ALTON: And now, we're gonna just tuck this into the pocket. -[GASPS] -Oh, that is so cute. -Now, we might have to go under the... little strap. DIANNA: Oh, I love it. ALTON: Ta-da. -And it's easy to take it to the party too. Gotta go. -Yeah. ALTON: I'm off to the holiday party. DIANNA: Oh, so easy. Here we are, back at the wrap bench where things are really gonna heat up. [LAUGHING] I'm very excited. And, Dianna, we're going to create something you may be familiar with coming from the island of Hawaii, a volcano. Yes! [LAUGHING] This volcanic wrap is both an innovative and a thematic way to wrap the gift that really plays off of Alex Wassabi's explosive personality. Because it's gonna blow up. I mean we're gonna blow the lid off this thing. So, the very first thing we're going to do is we are going to adhere this water bottle down to the center of our lid. -And, so, you've got a glue gun there. -Mm-hmm. Please tell me you've used a glue gun before.
