MARY: I have to put these balls in this bucket.
Whew.
I wonder if you could build a machine
to put balls in a bucket.
OVEJITA: [NON-ENGLISH SPEECH]
MARY: Great idea, Ovejita.
[SINGING] Yeah, yeah.
Want to know what it's all about?
Ask a question and let's find out.
Hey Liberty Science Center, can I
build a machine to move a ball?
ALL: Let's find out!
MARY: Oh, boy!
WOMAN: What we probably want to do,
Mary, is combine these simple machines
to make a more compound machine--
a whole bunch of machines working together.
MARY: Yes.
We'll put all the machines together
and make one big machine.
WOMAN: And we'll get that ball into our bucket.
Let's first start off with this piece here.
What does this look like to you guys?
GIRL: Seesaw.
WOMAN: A seesaw.
MARY: Seesaw.
Yeah.
WOMAN: A seesaw is an example of a simple machine--
MARY: How is it a simple machine?
What kind of simple machine is it?
WOMAN: It's a lever.
MARY: It's a lever?
WOMAN: Yeah.
It's actually something called a lever.
We can use the seesaw to lift things.
What about this piece here?
SAMANTHA: A slide.
WOMAN: Like a slide.
Maybe it can act like a ramp.
MARY: Will the ball slide on that?
WOMAN: Let's try it.
MARY: It worked!
What about that thing by Chris?
Chris, what is that in front of you?
What is that?
CHRIS: Like a drum that like, if you like drop a ball,
it could like bounce.
MARY: [LAUGH] It totally bounces, Samantha.
We'll be back to design our machine.
But right now, check this out.
GIRL: We love the letter L!
Ooh, ooh, lever!
Lobster on a ladder!
Lemons!
Lips!
L-l-lion!
Log!
Lights!
Look.
The letter L!
GIRL: [LAUGH]
BOY: What's the most fun way to get the ball from here
to all the way over there?
GIRL: Wheel.
BOY: Ramp.
BOY: Pulleys.
BOY: Lever.
GIRL: It really worked!
That was a quick way.
MARY: We're going to design a machine that
takes a ball from here all the way to here.
[LAUGH] Let's design.
WOMAN: So we have all our materials here.
I even have some tape here for you.
And what you guys are going to do
is start putting these things together
so we get that ball into that bucket.
Let's start experimenting.
Go ahead and try.
SAMANTHA: I think we should connect these.
BOY: THe table.
WOMAN: Why would you do that?
BOY: Because if we connect them, the ball
will go straight through, like a slide.
SAMANTHA: Yeah.
WOMAN: Think that'll work?
BOY: [INAUDIBLE] if you like put it back a little
so it doesn't go too fast and roll off.
MARY: We're going to keep designing our machine,
and we'll be back to test it out.
But right now, what's this?
KERMIT: Hello there.
Kermit the Frog, here.
And today I'm going to demonstrate my new invention,
the What Happens Next Machine.
Well, the What Happens Next Machine,
its purpose is to turn on my radio.
I will show you.
Over here is my radio.
This stuff here is not my radio.
It's part of the machine.
But right here is the radio, you see?
Now, I'm going to turn on this radio using
the principle of What Happens Next.
OK?
Now, I will next demonstrate how this machine
is going to go about doing its job.
Note this rope.
See this rope right here?
This rope goes up into the air, and across there, and down
to that sandbag.
See the sandbag?
OK.
Now, first of all, I'm going to cut this rope.
Now, when I cut the rope, what happens
next is that the sandbag is going
to fall down and land on this end of the seesaw.
See that?
OK.
What happens next is this end of the seesaw
goes down, which means that this end of the seesaw over here
goes up.
OK?
So what happens next is this rope right here,
which is tied to lid of this box,
is going to make the box open.
OK?
So what will happen next is this balloon, which is inside
the box-- see the balloon?
The balloon is going to go up into the air.
And you will note that the balloon
is tied to the switch of the radio.
So when the balloon goes up into the air,
it's going to turn on the radio.
See that?
OK.
Now you see, it used to be-- it used
to be that I used to have to walk all the way over there
to turn my radio on.
I did, indeed.
It would tire out my feet.
It would waste time-- but not anymore,
thanks to the magic of What Happens Next.
And now, for the first time anywhere,
the Kermit What Happens Next Machine!
First of all, I'm going to cut the rope, which
is going to drop the sandbag.
And here we go.
I cut the rope!
And-- and what happens next is the sandbag is-- hey, uh-- uh.
I guess there's-- I guess there's some sort of a tangle
or something up there.
Ugh.
Well, I guess what happens next when
you've got a tangled rope is-- is nothing.
So, uh, we'll just skip the sandbag portion of my invention
and get right on with the seesaw portion.
I'm going to give the seesaw here a push.
Ugh.
Well, I guess it-- ahh.
Well.
Well, the seesaw seems to be stuck here.
So what happens next is that we ignore the stuck seesaw,
and we'll move right over here to the box.
And what do you bet the lid won't open?
Let's see.
OK.
And now, we raise the lid on the box.
Hey.
There you go.
And what happens next is the balloon
is going to float up into the air
and it's going to turn on the switch and radio.
Uh, come on, balloon.
Hey, balloon.
I'll give it a couple of kicks.
Hey, listen.
Listen you balloon, I've had enough trouble today.
You float up in that air right now
or I won't be responsible for what happens next!
[MUSIC PLAYING]
Hey!
There you have it, a masterful invention--
when I get it all working-- a chain of What Happens Nexts,
which will enable me to turn on my radio from all the way
over-- from all the way over here.
And I don't have to worry now about where I am.
I don't have to worry about where my radio is ever again,
because I know that what happens next is-- what happens next is
that I have to get another radio.
[WHIMPERS]
MARY: It's time for--
OVEJITA: La gente in su barrio.
MARY: Yes!
The people in your neighborhood!
[SINGING] Who are the peeps that you
meet when you're walking down the street?
Oh, who are the people in your neighborhood?
Gotta say right away without delay?
They're the people that you meet each day.
OVEJITA: [HUMMING]
MARY: Oh, excuse me, sir.
JOSEPH: Hello.
MARY: Aww, are you one of the people in our neighborhood?
JOSEPH: I am.
MARY: What's your name?
JOSEPH: Joseph.
MARY: Oh, Joseph.
Well, what do you do in the neighborhood?
JOSEPH: I'm a kinetic artist.
MARY:A kinetic artist!
What's a kinetic artist?
JOSEPH: It's someone that makes art that moves.
MARY: [GASPS] Art that moves.
How can art move, Joseph?
JOSEPH: I'll show you.
MARY: Let's see!
Wow.
Did you see that?
Ooh.
Joseph, do you think you could show us more about kinetic art?
JOSEPH: I sure can.
MARY: How did you become a kinetic artist?
JOSEPH: Well, I've been making machines like this
since I was six years old.
MARY: Really?
JOSEPH: I use everyday objects.
For example, a soup spoon is not just a soup spoon.
MARY: It's not?
JOSEPH: It also makes a great track for a ball.
Here's a bottle.
A bottle isn't just a bottle.
It also rolls.
And then you've got to think about how
to connect them with movements.
MARY: Movement.
Oh, right-- kinetic movement.
JOSEPH: So watch this.
MARY: Let's see.
Ooh.
So that made the bottle roll.
What's your favorite kind of kinetic art?
JOSEPH: I love making Rube Goldberg machines.
MARY: What's a Rube Goldberg machine?
JOSEPH: It's a machine that performs a simple task--
MARY: Yeah?
JOSEPH: --in a very complicated way.
MARY: Do you think maybe you could build one of those today?
JOSEPH: I sure can.
MARY: Ooh.
What could you build?
What kind of machine can you build?
JOSEPH: Well, we could do a simple task,
like watering a plant.
MARY: Yes.
We'll make a plant watering machine.
We're going to see Joseph's plant watering
machine in action.
Ready, Joseph?
JOSEPH: Ready.
MARY: Start the machine!
JOSEPH: Yes!
MARY: Wow!
[LAUGH] Did you see that?
That was amazing!
I love to meet peeps in the hood.
BOY: One.
MAN: Coo-coo.
Coo-coo.
BOY: Two.

MARY: It's almost time for Elmo.
But right now, we finished our machine!
The ball is going to go through that tube, down the ramp,
into the lever, through the aluminum foil,
down down to the drum, and in to the bucket.
All right.
Here we go.
Let's test our machine!
Put the ball in, Samantha.
Boo-ya!
Great design, you guys!
Our machine worked, and just in time!
ELMO: Oooh.
Ooh.
What school is this?
ALL: [INAUDIBLE].
ELMO: Oh.
What are we going to learn today?
WOMAN: We are going to learn to dance Flamenco.
ELMO: Oh boy!
We're going to dance Flamenco!
