Good morning, everyone.
Oh! This connection is so slow!
Tell me about it. Dr Knowles, not impressed.
Oh, really, you two!
It's such a beautiful day
and you've got your heads stuck in those things.
Oh, not you as well, Miss Hucklebuck.
Honestly, you're all turning into robots.
Oh, sorry. No offence.
BELL RINGS Oh, not the bell!
Oh, get to work, you lazy lot.
We're live in five, four, three...
This is Brain Freeze.
With Dr Knowles...
Colin the floor manager
and Miss Hucklebuck.
Come on, everybody.
BOTH: It's time for...
Today we're asking...
Like all mammals, human eyes consist of a pupil, which lets light in,
a lens, which focuses the light,
and a retina on which the image is formed.
But different animals process light in different ways.
Human eyes are sensitive to the colours red, green and blue.
Some insects' eyes are sensitive to green, blue and ultraviolet.
And other animals like cats aren't very good at seeing
in colour at all, but they can see really well in low light.
That must be handy when they're looking for their cats pyjamas
Guess so. See you after this break.
Anyone for a game of tennis?
Oh, I can't believe you're all still staring at those wretched screens.
Right, that's it!
I'm confiscating all electronic gadgets as of right now!
Hey! I need that.
Oh, Colin, how am I going to do my hashtags on the Face-plop?
Come on. Come on. You, too, Miss Hucklebuck.
No, buts. It's time to get back to the real world.
-We're going live.
So, Dr Knowles, you were saying...
As we have seen, cats see well in low light,
but they don't hold a candle to the tarsier.
Huh? What's a tarsier?
This small Asian primate has eyes that take up
half the size of its head.
They're so big, they can't even move them.
Whoa, look at them!
He must be able to see really far with those whoppers.
Well, not really.
Their night vision is exceptional,
but they're not so great at distance.
The animal with the sharpest vision is the eagle.
When hunting, they can spot their prey from over 6km.
So, like, lots of animals have really good eyesight,
but they all work a bit different?
Different strokes for different folks.
See you next time, strokes.
Uh! I mean, folks.
And we're clear.
OLD-FASHIONED MUSIC PLAYS
Well...well, this is nice.
HE HUMS, SHE COUGHS
Oh, come on, Colin!
-Even you have to admit this is really boring.
I beg your pardon?
I mean, look at the Professor.
Oh, perhaps you're right.
OK, then, maybe just one selfie?
Ah, who's that? What? Cheese?
Who said cheese?
Did you take a picture of me
when I was asleep?
Oh, what are these cobwebs?
Who's your man with
the big eyes there?
What's he doing?
Colin. Colin, where are my shoes?
