字幕列表影片播放

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.
-Oh, have I ever. -ALTON: Okay, good.
And then the next thing we're going to do is we're going to take this...
-Mm-hmm. -Funny, this is not a matchable collar.
That's not the cone of shame?
-you want it to fit inside the base. -DIANNA: Mm.
I think that's looking pretty darn amazing.
Now, here we have a roll of volcanic rock paper.
-Hmm. -So, with precision, wrinkle this paper
DIANNA: My goodness.
[BOTH LAUGHING]
Who taught you how to gift wrap?
Only the most famous gift wrapper in the world.
The world's most famous gift wrap artist.
So, now what we're gonna do is we're gonna put some hot glue around here
and then we're gonna just fold over the edge and press it into the glue,
and then we're gonna work our way around.
I'm gonna probably burn myself, but...
And please do not burn yourself, although it is a volcano.
Ah, true, we have to have something molten.
So I think our volcanoes are looking pretty good here.
And now we're going to take these long strips,
and these are gonna go around the edge of this
-and kind of give it a... -Oh, fun.
-an island flair, if you will. -That's so fun.
I "lava" working with you.
-[LAUGHS HEARTILY] -[CHUCKLES]
I think that's the biggest laugh
-I've ever gotten for any of my puns. -That was a good one.
-Oh, man. It's looking like a thing, -ALTON: It really is.
and not just a crinkled brown blob.
-It looks great. Great job! -Thank you.
But at the wrap shop, you know, we like to take it from good to gooder, to the goodest.
So, I thought we'll add some ribbons to this coming out,
-like little streams of fire and molten lava. -DIANNA: I love it.
The trick to this is you just put a little,
dot of glue inside of the container,
and then this is like-- so it gives it that little leap.
Oh, Alton, I have these,
these bracelets, this gift for Alex, him and his siblings.
These are actually made from orange carnelian.
Ooh, those are really cool. That's really pretty.
Yeah, they're really beautiful. They're actually a type of mineral.
They're a mix of silica, quartz and iron oxide which is basically rust,
and that's what gives them the nice orange...
Sure, they kind of have, like, a rusty color to them.
Exactly. Some people believe it symbolizes family togetherness.
I'm sure he's gonna love that.
I think you could maybe use some of the thinner ribbon and just
-tie those on, kind of like lava rocks. -Yes.
I love it.
-ALTON: And they perfectly match the volcano which is great. -Mm-hmm.
I don't even know what to say. You have created a fantastic volcano.
And, now, I think we're ready for a little, uh, chemistry.
Yeah!
You know, I've seen this trick done in lots of science experiments,
but what is the actual science behind that?
DIANNA: So, we're mixing together baking soda and vinegar
which are an acid and a base.
It's called an endothermic reaction meaning it gets colder,
-Really? -Despite the fact that it's always been in a volcano.
-Right, right. -As these mix together, carbon dioxide gas is produced,
and it bubbles up and expands. And it'll actually push up
out of the volcano explosively, we hope!
-Really cool. -DIANNA: Yeah.
So, let's go ahead and put all your dry ingredients in there.
Baking soda first and then I've provided two different colors of pigment.
And if you don't mix the pigment, then it can erupt in two different colors.
There's the red and here goes orange.
-So, you have the gift, which is the donation, -Mm-hmm.
to the Make-A-Wish Foundation and I was thinking,
we could bind it up in this lava rock.
I love it.
And that way when this erupts, this rock will come out.
-So, I'll give you the lava rock -Okay.
and then you can fold up your gift for Alex.
DIANNA: All right. ALTON: And put it inside the lava rock.
-All right. That's awesome. -And that just goes in right in there.
-Okay I'm gonna-- -No dust.
-It's in there. -And then I'm going to create a stopper for you.
-Oh, excellent. -So that doesn't come out.
DIANNA: Awesome. So I just stuff that right here? ALTON: Yeah.
-Of course, every good mountain needs a name. -All right.
There we go.
ALTON: Mount Wassabi!
So, now we're gonna take our box
and we are gonna gingerly place it.
All right.
And now we're just gonna bind all this up with some iridescent ribbon.
Oh, your loops are a little floofier.
-That's 'cause I'm a little floofier. -[LAUGHS]
Take the ribbon, you fold it in on itself and you cut up on an angle,
and it creates that perfect little "V."
Oh, beautiful, look at that.
-Ta-da. -You are profesh.
I think the only thing we need to do is add the invitation card
-for Alex... -Actually, I have a card...
...to attach to the package.
DIANNA: ...that I brought. It's very nerdy.
-This is my black hole card. -Love a good theme.
Here's some fun facts about black holes,
they actually trap light.
So, the gravity from the black hole
will pull the light in,
and then the light will never escape.
-I don't even know what to say about that. -[LAUGHS]
I thought this will be so fun 'cause you can sort of hide
a little card right in the center of that black hole.
Oh, excellent. So, maybe that's where we'll put the invitation
-to Alex. We'll write it on the back of that. -Yes. Mm-hmm.
'Cause you know, he likes a challenge
-and that will be a challenge to find it. -Yeah. Mm-hmm.
All right, I'll just stick this right in here, and, now,
-you can just slide that under the bow. -Under the bow?
Under the ribbon.
Amazing!
Might I just say, I've had so much fun hanging out with you today.
-I feel like I've learned so much from you. -[CHUCKLES]
Likewise. So don't forget to tune in to Alex Wassabi's channel
for an explosive instalment of the Great Gift Exchange.
Happy physicsing, and...
-As we say here at the wrap shop, -BOTH: That's a wrap.
I don't know if I was supposed to say it with you.
-You were, but a little more enthusiastically -Okay, sorry.
-I was like, eh, that's a wrap. -[LAUGHING]
-That's a wrap! -CREW MEMBER: Killed it.
NARRATOR: Ho, ho, ho.
So, physics guru taught Alton Newton's laws of motion.
What would Alex think when he saw the explo-shown?
Oh, you get it.
Today I got a package from a fellow YouTuber
Oh, it's Mount Wassabi.
One, remove the tissue paper. Two, pour me in.
Three, two, one.
I just got this card from YouTube,
so I'm going to open it up.
"Dianna, all this holiday cheer does not need to end here.
"Choose one more creator for the giving train
"and let's start a whole new chain."
That's cool.
So, I guess I have an opportunity
to pick another creator.
So, I have to think about who I'm gonna choose.
