[Ada speaking]
-[sighs] -[Ada] Six, seven, eight.
That should be enough chairs for the audience. Nice design work!
All we need now is for someone to make a big entrance.
-I'm here! -[Ada, Iggy laugh]
Are the programs ready? Snacks? Tickets? What time does the audience get here?
I'm usually the one with all the questions.
Sorry. Since I've been taking piano lessons with my Great Aunt Rose,
I've gotten really good.
I can't wait for our first-ever
Saturday afternoon living room concert recital!
I'm excited too.
I'm nervous. And excited! But mostly nervous.
Everything's ready.
Chairs, tickets, programs, and our instruments, of course.
My musical beakers! Where music meets science.
And my Boom-Boom Blaster. Isn't it beautiful?
It's like a skyscraper made of drums. Call me Iggy Peck, drum architect.
-[cymbal crash] -Whoa! For me, it's less
about the loudness and more about the design.
-[laughs] Heya! -Mornin', hon.
Sharp-looking piano, Mr. and Mrs. T. Ought to be able to play
-a real nice, bouncy C. -Huh?
That's how my Great Aunt Rose talks about music.
It's so nice to see this old thing get some use.
-Remember how you used to serenade me? -[vocalizing] Oh, I still do, baby.
-[all laugh] -[yowls]
-[notes play] -[meows]
Your concert got me thinkin'.
I might want to dig out my old bass from the garage,
have a Saturday morning jam.
Sounds delicious! Make mine strawberry with toast.
My dad means a musical jam, Iggy.
When you make up music on the spot, just for fun.
That's awesome, and disappointing at the same time.
-[laughs] I'll get some strawberry jam. -Sweet. Thanks, Mr. Twist.
One hour, everybody. One hour!
[whispers] Did your brother turn into a human alarm clock?
No, he just promised to be our stage manager.
As long as I get to open the show with some of my magic.
I'm gonna pull a rabbit out of this hat.
-[squeaking] -Huh?
[sighs] One hour.
An hour? Oh, my gosh, I hope I practiced enough!
[growls] That's forever from now!
-Let's rehearse while we wait. -Okay. I can get my nerves out.
I don't know exactly how that works, but my mom always says it.
Great thinking. First, we need a running order.
No one said anything about running!
No, a running order is who plays first, second, and third.
We could all play together.
But then the audience won't get to see each of our talents.
-Iggy, you'll go first. -[gasps]
Your Boom-Boom Blaster will really wake up the crowd!
But everybody will already be awake.
-It doesn't have to be too loud. Whoa! -[cymbal crashes]
-Maybe I can just show it off. -Ada will play her musical beakers next.
-DJ Beakers in the lab. -[glass humming]
Then I'll play.
-[fingers crack] -[piano plays out of tune]
-Uh… [coughs] -[piano plays out of tune]
-[yowls] -Huh? I've been practicing for weeks.
-And I'm really good. -[classical orchestra plays]
When I play, it's like my fingers are dancing across the keys.
Like I'm two-stepping over the ivories.
Like this.
-[piano plays out of tune] -[yowls]
[both groan]
[growls] Where did all my talent go?
Aunt is gonna be so disappointed when she hears me.
Know what might help? Science!
We could solve this problem using the scientific method.
♪ Scientific method! ♪
♪ We have an observation ♪
♪ So we'll start with a question ♪
-Do research! -Form a hypothesis.
♪ And test with experiments ♪
♪ What do we find out? ♪
♪ Let's draw a conclusion ♪
♪ Write it all down And pass around the results ♪
♪ That's the scientific method! ♪
To start, we'll need--
A hippo-sissi-mist!
A hypothesis! We're gonna imagine an explanation.
Oh! Oh! Oh! I've got a hypothesis! Frogs.
-Frogs? -Go on.
One time when I was sick, I sounded really funny
and my mom said I had frogs in my throat! So maybe some got into the piano.
[frogs croak in harmony]
Let's test your hypothesis by looking inside.
Nope. No frogs.
-[note sounds] -[coughs] Just dust.
Or wicked fairy dust?
Maybe a fairy who hates music
could be trying to stop our recital by sprinkling bad fairy dust everywhere.
Interesting theory. Let's test it.
There. No more dust. Go ahead, Rosie. Play something.
-[piano plays out of tune] -[yowls]
-[both groan] -Guess it wasn't wicked fairy dust.
I was so sure.
Maybe it's my fingers. Great Aunt Rose always talks about limbering them up.
Must be it. Your fingers aren't warmed up.
Mm!
So we've just gotta give them a good workout!
[drum line playing]
[sighs] My fingers are in tip-top shape.
-[piano plays out of tune] -[yowls]
[sighs] We tried everything.
If we could see what was wrong, then we could fix it!
[groans] Just leave me here and do the recital around me.
Come on, Rosie! Scientists don't quit. We've got grit.
Here comes the Jelly-Jiggler.
[muffled chords playing]
-[meows] -Why is the Jelly-Jiggler jiggling?
Uh, the more important question is
what's that sound and why is it getting louder?
-[jiggling] -It's a Unicorn-a-saurus!
Take cover!
Uh, kids, I don't think that's a Unicorn-a-saurus.
Just your dad warming up his bass in the garage.
Your dad can make his bass sound like a Unicorn-a-saurus? Cool!
Or the sound of dad's bass was making the Jelly-Jiggler jiggle!
This we've gotta see.
[low rumble growing]
-Oh, hey, kids. -Hi, Dad!
[bass playing]
The sound of Dad's bass is making the Jelly-Jiggler jiggle.
I read about this and took some notes
in my Big Book of Discoveries and Inventions.
Come on.
Where ya going? It's been a while, but I didn't think I was that bad.
Loading the lab.
[thrilling music plays]
Here are my notes.
Sound pushes tiny air molecules around, which turns them into sound waves.
Neat trick.
[Ada] We usually can't see the waves, because they're teeny.
But Dad's bass is so loud
that the sound waves hit the Jelly-Jiggler so hard it jiggles.
Like this!
[all] Whoo!
[all laughing]
Too bad we can't see the sound of Rosie's playing.
Then we could figure out why it's so bad.
-Sorry, Rosie. -Hey, it's the truth, Ruth.
[gasps] Iggy, you're a genius!
-I am? -Own it, Iggy.
I mean, I am. I am!
Uh, why?
Because maybe there is a way we can see Rosie's music.
With an oscilloscope.
Of course! An oh-silly-oh-scope! Uh…
I mean, oh-sill-oh… Nope, that's not it.
An oscilloscope.
A machine that shows sound as lines on a monitor.
Oh! I'll design a simple one we can make.
Looks like we can make it with, let's see,
an old smartphone, a TV, an umbrella…
[gasps] And three jelly beans.
-What are the jelly beans for? -My mouth.
-[laughter] -Let's get to work!
[upbeat funk playing]
Great job, you two. Now let's put this oscilloscope to work.
Okay, Rosie. Ready when you are.
Ten minutes 'til showtime.
[squeaking]
-What? How'd that get there? -We've gotta hurry.
-[piano plays] -[Iggy] The oscilloscope's working.
But is that what music is supposed to look like?
It's so wonky.
Dad, play something funky.
You are in luck. "Funky" is my middle name.
[funky bass line plays]
Now, that looks more musical.
That means it's in tune.
See the curved lines follow a pattern? That's how you tell.
Wow! That is so cool!
Now you, Rosie.
-[plays out of tune] -Oh!
Those two sounds look totally different. Mr. Twist's funky music makes smooth lines
and the piano music makes wonky lines.
[sighs]
The smooth lines mean the bass is in tune,
so those wonky lines must mean the piano is out of tune.
That's what it looks like, and sounds like.
[gasps] Yay! It's not me or my talent.
Hmm, we can fix this.
We just have to tighten the strings the right amount…
-[notes sound] -…'til the piano is in tune.
Give me a bouncy C, Rosie.
-[note plays in tune] -[gasps]
That should do it. Play something.
[piano, bass play in tune]
-Yay! -I'm back!
The audience is here. Zero minutes, people. Zero minutes.
-It's showtime! -[triumphant music plays]
Cool!
-Yup. -[meows]
-[audience] Oh! -[Mr. Twist] Nice.
-[applause] -Woo!
Ladies and gentlemen, there's been a last-minute change.
Instead of playing solos, my friends and I will play as a group.
That's how we solved a big problem today. And that's how we work best. Together.
-Then we'd better get the toast. -Why?
-Because it's time to jam! -[drum solo]
[shrieks] But not too hard.
[all laugh]
[instruments harmonizing beautifully]
-[Mr. Twist] Hey! All right! -[Arthur] Yeah!
[audience cheering] Okay! Yeah!
Hmm. [gasps]
I have an idea. Let's meet another scientist. Come on!
[upbeat music playing]
Hi, I'm Susan Miziker.
And I'm Dr. Avila. We're both doctors of audiology.
We're here today to talk about how the ear works
and how you hear sound waves.
People come to us when they have a hearing-related problem.
We measure how people hear, whether you can hear soft whispers…
[whispers] Hi. How are you?
[shouts] Or loud sounds!
So the sound as I'm talking travels all the way into…
-My ear. -[Dr. Avila] There.
[Dr. Miziker] The ear funnels the sound to the eardrum.
The eardrum vibrates with the sound wave,
then the little bones that are attached behind the eardrum
send that vibration into the inner ear.
That's where the cochlea is.
The cochlea's very special,
because it turns the vibrations of sound into signals that are sent to the brain
so that the brain knows what you are hearing.
[Ada] Whoa!
Fun fact!
Earwax is actually good for you.
It protects you from particles of dust, and bacteria, and fungal infections.
-Even insects from getting into your ear. -[Ada] Gross!
Wasn't that cool? Science is the best!
[upbeat music playing]
[Ada speaking]
Hmm, just a few more colors and this unicorn painting will be done.
Unicorns love color!
[Rosie hums]
Dance floor is almost ready.
And party hats are almost glittery enough.
-[meows] -Oops.
-[meows] -[laughs] You're part of the glitterati.
Ew! Now it's stuck to my finger.
Why can't you ever get glitter off your finger?
-That's a question for "The Why Files." -Great question.
I have a question. Why does it look like a rainbow crashed into our backyard?
-We're having a party for… -[triumphant music builds]
-[all] Intergalactic Unicorn Day! -[Rosie grunts]
Never heard of it.
Does it have to have every color in the rainbow? And confetti?
The colors are rule number one for Intergalactic Unicorn Day.
The confetti is Rosie Rule Number One for life.
Rule number two of Intergalactic Unicorn Day,
you have to have a unicorn picnic outside.
And rule number three, you have to do a unicorn dance called…
The Unicorn Stampede!
[all neighing, laughing]
-Hey! -[gasps] Oops.
That was kinda fun.
Oh, phew!
You should come, Arthur.
Yeah. Unicorns love people.
The more, the merrier. That's just basic math.
Hmm, maybe.
I'm gonna get some tennis practice in before it rains.
Makes sense. You wouldn't want to get caught in the…
-[all gasp] -Rain?
[Ada] Uh-oh! Look at those clouds!
Well, not all clouds are rain clouds. Right?
-Right. But those are. -How do you know?
Because those are nimbostratus clouds.
Nimbo-what-us?
Nimbostratus. They're low, gray, and spread flat across the sky.
When they show up, it usually means there's going to be a lot of…
-[rain pouring] -[meows]
-[all gasp] -Rain! Quick, pack it up.
[all grunting]
Oh!
[sighs] Looks like everything's still in good shape for the party.
What party? We can't have a party in the rain.
Why not? Little known fact about unicorns.
They love the rain!
Or at least I do.
What's not to love?
I mean, the moisture in the air forms clouds,
which turns into rain, and that's so amazing.
But our stuff'll get all wet. And so will we!
Hmm, maybe there's a way to have our party in the rain without getting wet.
We need a brainstorm.
A rainstorm brainstorm! Woo-hoo!

[gasps] What if we made a rain-away machine?
-[crackling] -[triumphant music plays]
[birds chirping]
-Woo! -Nice!
But building that might take a while
and Intergalactic Unicorn Day will be over.
-Then this would be for nothing. -So we need something else.
We can make a tent out of umbrellas.
But what about the spaces between the umbrellas?
Definitely too holey.
But we could make a big umbrella tent.
Less holey, so the rain won't fall on top of us.
But rain could blow in through the sides.
-Yeah, gotcha! -True.
[all groan]
-[all sigh] -We need to build something to cover us.
-Like a shed? -Yeah!
That'll work! I'll start building now.
Hold your unicorns, Rosie.
We can't start building yet. We need to design it first.
You know, think it through, make a plan, draw it out.
You're right. I was super excited. Got way ahead of myself.
-And that's what we love about you. -[giggles]
Maybe a square shed. Big enough for a Unicorn Stampede.
With a slanted roof. I love how they look!
How's this?
-Love it! -Looks great!
So can I build it now?
-Yeah! -Yup!
Yeah!
[all laugh]
[giggling]
[all gasp, sigh]
After we get our rain gear.
[upbeat music playing]
[twisting, pounding]
[Iggy] Amazing!
Our rain shed is done!
I love it! Let's test it.
[all laugh]
-We have a dance floor for the wet ground. -And a picnic blanket.
-Looks like we can have a picnic. -Fab! We need to test the walls
to see if they can take a…
[all] Unicorn Stampede?
[all neighing, laughing]
-[rattling] -[cheering]
-[Rosie] Whoa! -[Iggy] Uh…
The walls are caving in.
Quick! Out of the way! Prance, unicorns, prance!
-[crashing] -Yowza!
[Ada] Oh!
-[Iggy] Yikes! -[Rosie] Boy.
-Bad news, we need another shed. -Is there good news?
Puddles!
Woo!
[all laughing]
[gasps]
Guys, I know what we need for our new shed!
We should put beams up shaped like an "X," like that.
They're called crossbeams. They'll support the walls!
My Great Aunt Rose taught me when we built my dollhouse.
[groans]
[all cheer] Yes!
Now complete with crossbeams and a stylish flat roof.
I love the design.
Me too. Let's test it.
First, picnic.
So far, so good. Roomy and dry.
Next, the Unicorn Stampede dance.
[all neighing, laughing]
[Rosie] Yeah!
[neighing continues]
Come on. Yee-haw!
The walls didn't cave in!
-[creaking] -Huh?
[muttering] Roof falling.
-Can't move! -[Iggy gasps]
Iggy!
-[all gasp] -[crash]
Aw, phooey! I really thought that was gonna work.
-[sighs] I thought so too. -Let's dry off and think about this.
[sighs] We made two sheds, but neither of them worked.
And if we don't fix it, we're gonna miss Intergalactic Unicorn Day.
[sighs]
Hey, we're scientists, right?
-Right. -Yeah.
-And do scientists quit? -[both] No.
'Cause we've got grit!
Grit! Yeah!
-I don't know if I do. -You do.
Let's look at what went wrong so we can figure out how to make it right.
Hey, now you're speaking my language.
-Loading the lab. -[Rosie] Awesome!
[cheering]
[thrilling music plays]
Okay, we recreated the sheds. Let's check them out.
On my shed, the walls fell in.
Right. And on my shed, the walls stayed up, but the roof collapsed.
So why didn't Rosie's walls cave in?
Maybe 'cause I used crossbeams. But why did the roof collapse?
Rosie's roof was flat,
so all the rain collected on top, then it got too heavy and collapsed.
The slanted roof was more than just a cool design, Iggy.
It let the water roll off it. [gasps]
I think I just connected the polka dots.
Both sheds had stuff that worked and stuff that didn't,
so what if we build a shed using the walls from Rosie's to make it strong,
and the roof from Iggy's, so the water runs off?
Oh! I like that!
Me too. Let's hurry so we can still enjoy…
[all] Intergalactic Unicorn Day!
-Yeah! -Let's do it.
[all laugh]
[upbeat music playing]
[Ada] Awesome possum.
-Woo-hoo! Yes! -Let's test it out.
It's perfect for a picnic.
And now, the moment of truth.
Unicorn Stampede!
[all neighing, laughing]
[neighing, laughing continue]
Hey, the walls aren't falling over.
-[Rosie] The roof is staying put! -[Iggy] Wow!
Nice! Let's finish setting up.
[gasps] Oh, no, Rosie.
The rain smudged your painting.
Oh! It looks even better. Unicorns love when colors mix together.
It's more magical.
Hey, cool shed.
Uh, wanna come in, Arthur?
-Sure. -You need a party hat.
[laughs] One for you too, Mooshu!
[meows]
Ada, could you please pass the rainbow sparkles?
[all laugh]
Mm, these rainbow sparkles are delicious. Must be in season.
[all laugh]
I could use some, um, sparkling rainbow juice!
Ah! Sparkling rainbow juice is so refreshing.
Huh. Mooshu wants some too.
[all laugh]
Now, I think it's time for the…
[all] Unicorn Stampede!
[all neighing, laughing]
[upbeat music fades out]
Hmm. [gasps]
I have an idea. Let's meet another scientist. Come on!
Hi, I'm Eletrice Harris and I'm an architect.
Today, I'm gonna show you one of the houses I designed.
[Ada] Let's go!
Any building or structure that you walk into, an architect has designed it.
It could be a hospital, a school, a library, your home.
So, for every structure that we design, we do a set of plans.
And these are called blueprints.
And so the blueprints, it shows the walls, it shows the windows,
it shows the doors. We even put in where the toilet should be.
-[Ada] Hmm. -[toilet flushes]
Just like we have skeletons in our body, buildings have the same thing.
We call this our skeletal frame.
[Ada] Whoa!
One of the most important things when building a structure or house
is to make sure it will withstand the elements.
The rain, the wind, storms.
So the two structural components
that are important to making a structure sound
are the beams, which are horizontal,
and columns that are vertical.
This is what a doorway looks like in plans.
This is what it looks like when we frame it out.
So this would be our beam and these are our posts for the doorway.
So, here's a finished product of a doorway.
And if you could imagine that that beam is across the top
and the posts are along the sides.
Fun fact!
Architecture was a part of the Olympics. To compete, you had to design
a sports-related structure.
[horns play]
Wasn't that cool? Science is the best!
[closing theme music playing]
