Rainbows are formed when sunlight passes through water droplets in the air, requiring both rain and sunshine to appear simultaneously; this occurs because light refracts and reflects within water droplets, separating white light into its component colors (red, orange, yellow, green, blue, indigo, violet).

Chasing Rainbows | Darwin & Newts | S1 | E6Added:
Let's science this. I'm on it. Come discover the world around us.
>> We'll observe nature's wonders >> using science and imagination.
We'll experiment and build creations.
Darwin and >> having fun [music] with trial and error.
Darwin and you bringing all their friends together.
[music] Find out how things work with [screaming] A rainbow.
Looks >> na.
>> Look [screaming] there above that tree with the sun on it where the rain is.
>> A rainbow.
Oh, it's so pretty.
Rainbow, rain, sunshine.
Those colors. Red, orange, yellow, green, blue, indigo, violet.
Oh, wow.
Those colors are so amazing.
I wonder what they feel like. Feel like?
>> Yeah. I'd love to touch a rainbow.
>> Nes, that idea is awesome. [screaming] >> Let's touch that rainbow.
Hey, Burpee.
>> You love water, right?
>> Oh, yeah. I know.
>> Well, stay right there.
>> Okay.
>> I'm going to get water from the stream to go through this hose and into the sprinkler, and you'll get nice and wet.
Here goes.
Water coming any moment now.
H I'm going to have to think about this.
>> What did you do with a try? Made it better. Made it faster.
Yeah.
>> Hey, what are we looking for? The rainbow was at the top of a bed tree.
So, look for a big tree. We're in a forest. It's full of big tree.
>> Race you to the rainbow.
>> You better watch out this time, Burpee.
When I pour this water, it'll go down the hose and come out the sprinkler.
Yes.
What will the rainbow feel like, Darwin?
Smooth, soft?
I don't know. Maybe the red bits of the rainbow will be warm and the blue bits will be cold. We'll find out soon enough.
We're almost at the top. Here goes.
Hey, where's the rainbow? What's that?
There's no rainbow anywhere.
What's going on?
>> Let's see. There's no rainbow, no rain, and no sunshine. Wait, look.
There's another rainbow over there.
Whoa. Yes. Above that hill. Let's touch that rainbow. Come on.
So, will the the rainbow be heavy?
If we push it, will it move? Well, we'll find out when we get there. My turn to pedal.
Almost there.
Almost there. I'll push. So will I.
[screaming] >> Wait. Why do we need the trike?
Oh yeah.
[laughter] Come on.
Are we there yet?
Are we there yet?
We're there. But the rainbow isn't.
There's just all this rain.
Found rain.
No sun.
No rainbow.
This chasing rainbows is harder than it looks.
Wait, another rainbow.
>> Where?
>> There. On that really big cliff. See the one with rain and sunshine on it.
Rain and sunshine.
Let's climb it.
>> What am I doing now?
>> Wow. If I put lots of water way up high, then the sprinkler will work better and water my whole garden.
>> I think you can go near the sprinkler now, Burpee. It won't go till I turn this stick.
use. I think I almost worked out why there was no rainbow just then. I think you need more than one thing to make a rainbow with the really big. We've found it.
Yes, there's a rainbow at the top of it.
And this time we'll touch it for sure.
But how do we get up there?
I'm on it. Presenting my latest invention, the Absel windup kit. Rainbow, here we come. Wa, we're so high up. You can say that again.
Wow, we're so high [screaming] up.
Made it. Here, I'll pull you up. meddle.
[screaming] >> Oh no, the rainbow's gone again.
>> You're right. There's sun, but there's no rain and no rainbow.
How can this happen?
Where do they go? Well, I'm not going anywhere till we figure out what makes rainbows appear.
Let's science it.
When we first saw the rainbow over the tree, it was raining and the sun was shining.
Yes. But by the time we got there, there was no rain and no sunshine and no rainbow.
But then we saw another rainbow over the hill where it was raining and sunny. But by the time we got there, there was rain but no sunshine and no rainbow.
>> Then we saw another rainbow right here over this big cliff >> where it was raining and sunny again.
But when we got here, no rainbow.
Rain, but no sunshine. Sunshine, but no rain.
I've got it. Two things make a rainbow.
Rain and sunshine.
You're right. That's so clever, darling.
>> Thanks, Nes.
Oh, but you never got to touch a rainbow.
>> I don't mind. I've had heaps of fun chasing them. And we'll have more fun getting down from here.
>> Will we?
[screaming] [crying] >> Shut.
>> Hi. What have you two been up to?
>> Chasing rainbows.
We wanted to touch one and see what it feels like. Cool. So, what does a [music] rainbow feel like? We don't know. We never got to touch one. But we learned what you need to make a rainbow.
Sunshine and water. Sunshine and water.
I think I can help. What do you think she's doing?
>> I don't know. We already have sunshine.
Here comes the water making it rain.
[screaming] >> Awesome.
>> It's a rainbow.
>> And it's a rainbow you can touch.
>> 3 2 1 go.
>> [screaming] >> Woo!
