How come we got stuck selling light bulbs?
Yeah, whose 'bright' idea was this?
CAR-LOS.
At my old school we sold chocolates for the Valentine's Day Fund Drive.
Uh£¡ How many light bulbs do we have left?
All of them£¡£¡
Come on, you weasly wimps, there's gotta be someone around here who'll buy one.
Hey look£¡
ls it just me, or do those plants remind you of someone?
Hmmm...lt's Ms Frizzle's house£¡
Come on, guys£¡ Ms Frizzle will buy a lightbulb...maybe two£¡
Hurry£¡
l hope she is here
What kind of doorbell is that???
A Lizardy Bell?
CAR-LOS£¡£¡
How does it work?
lt's easy, Arnold£¡ Just flip up the handle like the arrows show. See?£¡
l didn't hear anything.
Maybe it's broken.
Maybe you broke it, Wan£¡
Me?
Oh no£¡ You think l did?
Perhaps...
Possibly...
Probably£¡ l'd better go find Ms Frizzle - if she's home...
Maybe she's in the backyard. Come on£¡
There's the bus£¡ She must be home.
There she is£¡
...You must know what l'm talking
about when l say there's always been a real attraction' between the two
And when they 'join together', the sparks really fly.''
l certainly DO know what he's talking about...£¡
Oh, Liz£¡ That must be him now.
Miss Frizzle, here.
Oh, hi, it's Valerie. l was hoping it was you.
l positively need you. You always do give me a charge.
Did you hear that?
Shhh£¡
Oh yes£¡ lt would just spark up my day.
l would love it if you'd come ring my bell. Fifteen minutes? l'll be waiting.
Just a little bit more.
Ah perfect£¡
Wow£¡ So that's how she gets her hair to do that£¡
Forget her hair£¡ Think of what she said£¡
''l positively need you... you give me a charge'' Tim - Ms Frizzle's in love£¡
Guys£¡ Guys£¡ Guys£¡ Ms Frizzle has a secret Valentine£¡
We heard her invite him over£¡
Ms Frizzle has a Valentine? But...
but she's our teacher£¡
She said, lt would mean the world to me if you'd just come over and ring my bell...''
Too bad he won't be able to hear it.
You're right£¡ l broke it£¡
Maybe we just better go tell Ms Frizzle what happened.
Keesha£¡ Are you kidding??£¡?
This is the love of her life we're talking about.
He's on his way to ring her bell - now£¡
We're just going to have to fix the bell before he gets here.
Good idea, Wan. Only one problem£º we don't know how.
Ever get the feeling you're being watched?
LlllllllZ£¡£¡£¡
Uh...hi, Liz.
This is good.
lf we go in, maybe we'll be able to find out how the bell works so we can fix it.
Sounds like a plan to me£¡
Uh. Happy Valentine's Day, Liz£¡
Uh huh£¡ The bell runs on electricity from that battery.
lt looks like everything in this house runs on batteries.
lt does indeed, Wanda£¡ Safe but powerful, don't you think?
Ms Frizzle£¡£¡£¡
What a lovely jolt it is to see you all on a Saturday£¡ Come in... come in£¡
Got any ideas?
Not yet...
Um... we're, uh, selling light bulbs for the Fund Drive
but it looks like you have plenty of them already.
Bright lights - big electri-city£¡
That's my motto, Arnold.
Hey, Tim£¡ Over here£¡
Look at this£¡
Yeow£¡
Snappy spark, Wanda£¡
Where'd it come from?
lf you really want to see - you'll get a charge out of these£¡
l call 'em 'SPECS'£º Special Electrical Charge Spotters.
l'll just grab a balloon. Brush firmly and...
Ms Frizzle£¡ There's red stuff piling up on your hair£¡
And blue stuff on the balloon£¡
ls that stuff - electricity?
They're electric charges, to be exact£¡
The specs colour them red and blue so you can see them.
You're right, Ms Frizzle£¡ Without the specs, the charges are invisible.
But they're all around us£¡
The two kinds of charges like to stay together,
but when l rub my hair with the balloon, the rubbing pulls them apart.
Red charges tragically separated from blue charges
Longing for each other?
But what makes a spark?
When blue and red charges join back together again, ooo, sparks fly£¡
l get it. Rubbing the balloon separated the charges
And when they came together again, they sparked
As my Aunt Salt used to say about my Uncle Pepper£º opposites attract£¡
Ahhh£¡ Romantic, isn't it?
This is serious£¡
So a spark is what happens when opposite charges quickly move back together.
A positively electric conclusion, Tim£¡
So, is the electricity inside things like lights and...
doorbells... also charges trying to move back together?
Yes it is£¡ lf you could go inside this wire that's what you'd find -
moving charges£¡
Speaking of which...
...l'd better get moving. So if you'd like to keep the goggles...
Gee thanks Ms Frizzle. We'd better get moving, too.
Are you sure? Because, you're welcome to stay.
No, no, l'm sure you've got something really important to do.
We'll just let ourselves out.
ln that case, l'll get ready for my big connection£¡
This man must be important if she calls him her big connection£¡''
And the Big Connection will be here any minute£¡
What do we do now?
We've got to fix that doorbell.
Uh, Liz?
To the Bus£¡
l hope this works...
Great job, Liz£¡
Now somebody throw me a walkie talkie£¡
Here you go, Wanda£¡
So, what's the plan?
l thought you guys could check out the doorbell while l keep a lookout for Ms Frizzle£¡
Hit it, Liz£¡
Hey£¡£¡£¡£¡
Not the lightbulb, Liz...the doorbell£¡£¡£¡
Wowwww! I've never seen a lightbulb from the inside out before!
What's it like?
lt's really cool£¡
Correction - it's really hot£¡
Let's get outta here£¡
Wait£¡ Can you get inside the wire like Ms Frizzle said?
lf we find out what makes the bulb light up,
Now that's a bright idea.
Amazing£¡ They're inside the wire.
Liz?
ls that you?
Watt are you doing? Oh, that's a good one... Watt are you doing?
Oh, l do love electric jokes... especially if they're shocking£¡
Hey you guys£¡
What's happening inside that wire?
lt's really cool Wanda£¡
The inside of the wire is filled with electric charges and they're moving.
lt's like a river.
And we're getting swept downstream.
Right. lt's as if we're being...
...carried along by the current£¡
That must be what they mean by electric current£¡
Whoooaaaa£¡£¡£¡
Where are we going?
Wherever those charges go.
lt's getting really crowded in here£¡
And hot£¡ l'll bet we're inside that skinny wire in the bulb.
According to my research, this skinny hot wire we're in is the filament.
lt's what makes the light bulb glow.
Look, it's so narrow. The charges are rubbing and squeezing to get through.
Electric charges on the move.
Don't worry.
You're travelling through he wire from the bulb to the battery.
Hmm. We must've been pulled in by those red charges behind us.
Opposites attract, remember?
But now we're being pulled along with all the blue charges.
Cool£¡ Now you're out of the battery£¡
And heading down the other wire back to the light bulb£¡
Oh, no£¡ Here we go again£¡
According to my research,
which is very hard to do when going around like this...
...the circular path we're caught in is called an electrical circuit.
l get it£¡
That's it£¡
The light bulb works because the battery makes the electrical charges
move through wires to the lightbulb to the wire again...
... back to the battery - around and around£¡
And the moving charges heat up the filament in the bulb as they go past.
Ah, sweet mysteries of life.
Wanda£¡ What's the matter?
Shhh£¡ lt's Ms Frizzle£¡
lf there's no flow, it's no go -
and if it's no go, then there's no glow...
Oh poor Miss Frizzle. This is worse than l thought£¡
Ms Frizzle's gone out to the garage.
lt looks like she's decorating the whole place with heart-shaped lights.
Wanda, help£¡£¡ Here we go again£¡£¡
We can't stop going around and around this circuit.
l think l'm going to be sick£¡
Not as sick as Ms Frizzle'll be if we don't fix the doorbell£¡
Only she'll be lovesick£¡
What happened? We've stopped moving£¡
Everything's stopped moving£¡
The electric charges aren't going anywhere£¡
lt's like Ms Frizzle said, lf there's no flow,
it's no go and if it's no go, there's no flow.
But if l complete the path of the wire again - Whoaaaaa£¡ We're moving£¡
Break the path - again- you stop£¡ Get it?
We stopped£¡
Flow£¡ No flow£¡ Flow£¡ No flow£¡
We got it Wanda - we got it£¡£¡£¡£¡
lt's like traffic going over a drawbridge...
When the drawbridge goes up...
... the traffic stops. When it goes down and, completes the path...
...the traffic can move again.
But Wanda, if we don't move out of here...
Ms Frizzle's BlG connection will come and try to ring her bell...
you're right.
Through no fault of her own, the bell won't work...
So, she won't know he's there.
But he'll think she's not answering on purpose...
that she doesn't love him anymore£¡
And then...
He'll leave£¡£¡
Ms Frizzle's happiness will be ruined... forever£¡
Liz, you've got to get out of there£¡
We've got to fix that doorbell£¡
So here's the battery that makes the electric charges move to the doorbell...
and here's the path they move along.
Wanda£¡ ls the doorbell switch still in the 'on' position,
so the charges can flow?
Good question, Tim. l'll go check.
Bell switch on£¡
Okay£¡ From what we can see, the wire runs from the side of the battery to...
...the 'on-oft switch...
Then it connects up with the motor that makes the hammer hit the bell...
...and runs back to the battery to complete the circuit.
So it should work.
But it doesn't£¡
Since the bell isn't going, the charges must not be flowing£¡
There must be a break in the path somewhere - and if there is,
you'll find it, right?
Right£¡£¡
Just as we thought, none of these charges are moving...
lt's just like it was in the lightbulb when Wanda stopped the flow.
lt's no use, Liz, those charges aren't going anywhere.
There's a break in the path somewhere
And it's up to you to find out where it is£¡
You got it, Wan£¡ We're heading out on foot£¡
You better hurry - or Ms Frizzle and her Valentine
will pass like opposite charges in a battery£¡
Did you find anything yet?
Man, it's like a traffic jam in here£¡
Nothing is moving£¡ These charges are stuck£¡
Wait£¡ l think l see something£¡
Come on, everyone£¡ Let's make like electricity and charge£¡
We're almost there£¡
Wowwwwwwwwwwww!!!
l guess we found the problem£¡
The wire is broken£¡
You said it.
And it's a long way.......doooowwwwwwwnnnn!!!!
RALPHlE£¡£¡£¡
What happened??£¡
What's going on??£¡?
We found the break in the wire.
Some charges are red, others are blue.
Hook up the wires and light will come through.
lt won't be long now...£¡
HEEELLLLPPPPP£¡£¡£¡£¡£¡£¡
That's better.
Positively electrifying£¡
Whew. That was close.
Too close£¡
You guys all right in there?
We are now£¡
Where's the break?
Maybe l can fix it from out here.
lt's between the motor and the battery£¡
Between the motor and the battery...
The switch is off, to be on the safe side... Now...
...the wire goes from the switch and the motor...
and then from the motor to ... the break£¡
Right here£¡
That's it, Wanda£¡
Alright Wanda£¡
You found us£¡
The electric charges need a way across£¡ Can you build us a bridge?
l could if l had some wire or something else metal...
Waitasecond£¡
Yes£¡
May l have one of those?
Thank you£¡
l found some tin foil£¡
Where?
Oh, the chocolates. l'm going to try to wrap it around the wires.
l hope this connection works£¡
lt looks good from here£¡
lt better - or this love story's going to have an unhappy ending£¡
Everyone back in the bus?
Ready£¡
Here we go£¡
Path... complete£¡£¡
We did it£¡ We did it£¡
YEOWWWWWWWWW£¡£¡£¡
Quick everyone£¡ Hide£¡ Or Ms Frizzle will see us£¡
Where is she? No way she wouldn't have heard that bell.
Well if she's not inside, l bet she's back out at the garage. Come on£¡
She's not here£¡
Maybe she's inside the garage£¡
Ms Frizzle£¡ Are you in there?
The door's jammed shut.
And if she's in there, she'll miss her big connection.
No wonder£¡
Check out that yucky old battery£¡
lt's all rusty. l bet it doesn't work.
And if the battery doesn't work, then the charges aren't moving
lt's like there's a break in the circuit, just like the doorbell.
But to open the door, the charges have to move from the battery,
in through the switch, to the motor and back again.
All we have to do is get a new battery.
But before we do anything, let's turn the switch off, just to be safe.
But where are we going to get a battery like that?
A battery bus.
Way to go, Liz£¡
And now ladies and gentlemen, the switch goes on.
We did it£¡ We've got flow and go£¡
HOORAAAAAAAAAAAAAAAY!!!
Ms Frizzle??
She's not in here£¡
Where'd she go?
Looks like she flew with the flow, out the door£¡
Uhh£¡ lt's Ms Frizzle's big connection£¡
He's here.
Ah, there you are, class. l want you to meet Mr. Ampere - my...
Your electrician??£¡?
You kids did a bang-up job fixing this doorbell.
You knew the doorbell was broken, Ms Frizzle?
Of course l knew, Wanda£¡ l called Mr. Ampere the minute l found out.
But l see you did my work for me.
You kids really know your electricity.
You might say we're...'electric fans'£¡
That must be Carlos.
He is indeed£¡
And now that the bell is working,
everyone ready for a transforming experience?
Whatever you say, Ms Frizzle.
Good£¡
lt's my big connection£¡
One end of my wire connects to the doorbell motor
and the other connects to the switch to make...
one magnificent circuit£¡
Mr. Ampere, would you care to light up my life?
l've been waiting for this moment for a long time, Ms Frizzle.
WOWWWWWWWWWWWWW£¡£¡£¡
Reminds me of old times down at the power plant.
l got the idea from reading your latest pamphlet..
''when joined together the sparks really fly£¡£¡£¡''
Pamphlet?
But ...l thought it was a love letter -
When they join together the sparks really fly£¡'' Who knew?
Say, are those light bulbs for sale?
You bet£¡£¡ Would you like to buy one?
One? l'll take them all.
Well class...
Consider yourselves sold out£¡ Happy Valentine's Day, everybody£¡£¡£¡
Happy Valentine's Day£¡£¡£¡
Magic School Bus, the producer speaking.
Hi, l just saw your show on electricity,
and my mom told me never to play with electricity in my house.
Batteries are fine, she said,
but the electricity we use to power our homes is very dangerous.
Your mom's right.
We made the electricity in Ms Frizzle's house all come from batteries -
so it would be safe for the class.
Flashlights, for example, are safe to handle.
But the electricity in your house is much, much more powerful -
and as you said, can be dangerous.
That's right.
You should never, ever touch bare wires - any place, any time.
Right£¡
And don't ever play with electrical cords, plugs or outlets, either.
You got it. And don't forget, electricity and water do not mix£¡
Never fiddle with anything electrical around a sink, bathtub or shower.
One more thing. Opposite charges are really called plus and minus charges right?
Right£¡ They're called that so you can tell they're opposites.
Bye£¡
Magic School Bus.
What about the colours of the charges?
Electricity isn't really red and blue, is it?
Well, charges are really invisible,
so we used the specs to ... colour them red and blue...
and to make it easier to tell them apart.
Well, l thought it was pretty cool.
l'm glad - thanks for calling£¡ Bye£¡
Oh Liz£¡ ls that for me?
And these are... for you£¡
This is great, Liz£¡ Happy Valentine's Day£¡
