0:00:02 > 0:00:04Good morning, everyone.
0:00:04 > 0:00:07Oh! This connection is so slow!
0:00:07 > 0:00:11Tell me about it. Dr Knowles, not impressed.
0:00:11 > 0:00:13#Awkward
0:00:13 > 0:00:14Oh, really, you two!
0:00:14 > 0:00:16It's such a beautiful day
0:00:16 > 0:00:18and you've got your heads stuck in those things.
0:00:18 > 0:00:21Jonathan, selfie!
0:00:21 > 0:00:23Cheese!
0:00:23 > 0:00:25Oh, not you as well, Miss Hucklebuck.
0:00:25 > 0:00:28Honestly, you're all turning into robots.
0:00:28 > 0:00:30Oh, sorry. No offence.
0:00:30 > 0:00:33BELL RINGS Oh, not the bell!
0:00:33 > 0:00:35Oh, get to work, you lazy lot.
0:00:35 > 0:00:38We're live in five, four, three...
0:00:38 > 0:00:41This is Brain Freeze.
0:00:41 > 0:00:43With Dr Knowles...
0:00:43 > 0:00:46Professor McCork...
0:00:46 > 0:00:49Colin the floor manager
0:00:49 > 0:00:52and Miss Hucklebuck.
0:00:52 > 0:00:53Stand by!
0:00:53 > 0:00:56Come on, everybody.
0:00:58 > 0:01:00BOTH: It's time for...
0:01:03 > 0:01:04Today we're asking...
0:01:06 > 0:01:11Like all mammals, human eyes consist of a pupil, which lets light in,
0:01:11 > 0:01:13a lens, which focuses the light,
0:01:13 > 0:01:15and a retina on which the image is formed.
0:01:15 > 0:01:18But different animals process light in different ways.
0:01:18 > 0:01:22Human eyes are sensitive to the colours red, green and blue.
0:01:22 > 0:01:26Some insects' eyes are sensitive to green, blue and ultraviolet.
0:01:26 > 0:01:28Ultraviolet? Cool!
0:01:28 > 0:01:31And other animals like cats aren't very good at seeing
0:01:31 > 0:01:34in colour at all, but they can see really well in low light.
0:01:34 > 0:01:37That must be handy when they're looking for their cats pyjamas
0:01:37 > 0:01:39at night-time.
0:01:39 > 0:01:42Guess so. See you after this break.
0:01:44 > 0:01:46Anyone for a game of tennis?
0:01:46 > 0:01:50Oh, I can't believe you're all still staring at those wretched screens.
0:01:50 > 0:01:52Right, that's it!
0:01:52 > 0:01:55I'm confiscating all electronic gadgets as of right now!
0:01:55 > 0:01:57Hey! I need that.
0:01:57 > 0:02:01Oh, Colin, how am I going to do my hashtags on the Face-plop?
0:02:01 > 0:02:03Come on. Come on. You, too, Miss Hucklebuck.
0:02:03 > 0:02:04But...Jonathan.
0:02:04 > 0:02:07No, buts. It's time to get back to the real world.
0:02:07 > 0:02:10- BELL RINGS - We're going live.
0:02:14 > 0:02:17So, Dr Knowles, you were saying...
0:02:17 > 0:02:19As we have seen, cats see well in low light,
0:02:19 > 0:02:22but they don't hold a candle to the tarsier.
0:02:22 > 0:02:24Huh? What's a tarsier?
0:02:24 > 0:02:27This small Asian primate has eyes that take up
0:02:27 > 0:02:28half the size of its head.
0:02:28 > 0:02:31They're so big, they can't even move them.
0:02:31 > 0:02:33Whoa, look at them!
0:02:33 > 0:02:36He must be able to see really far with those whoppers.
0:02:36 > 0:02:37Well, not really.
0:02:37 > 0:02:39Their night vision is exceptional,
0:02:39 > 0:02:41but they're not so great at distance.
0:02:41 > 0:02:44The animal with the sharpest vision is the eagle.
0:02:44 > 0:02:49When hunting, they can spot their prey from over 6km.
0:02:50 > 0:02:53So, like, lots of animals have really good eyesight,
0:02:53 > 0:02:55but they all work a bit different?
0:02:55 > 0:02:56Exactly.
0:02:56 > 0:02:58Different strokes for different folks.
0:02:58 > 0:03:00See you next time, strokes.
0:03:00 > 0:03:02Uh! I mean, folks.
0:03:03 > 0:03:05And we're clear.
0:03:05 > 0:03:07CLOCK TICKS
0:03:07 > 0:03:10OLD-FASHIONED MUSIC PLAYS
0:03:10 > 0:03:12Well...well, this is nice.
0:03:12 > 0:03:16HE HUMS, SHE COUGHS
0:03:18 > 0:03:20Oh, come on, Colin!
0:03:20 > 0:03:24- Even you have to admit this is really boring.- Mm-hm.
0:03:24 > 0:03:26I beg your pardon?
0:03:26 > 0:03:29I mean, look at the Professor.
0:03:29 > 0:03:31HE SNORES
0:03:33 > 0:03:35Oh, perhaps you're right.
0:03:35 > 0:03:37OK, then, maybe just one selfie?
0:03:37 > 0:03:39Yay!
0:03:39 > 0:03:41Say, "Cheese!"
0:03:41 > 0:03:43- ALL:- Cheese!
0:03:43 > 0:03:45Ah, who's that? What? Cheese?
0:03:45 > 0:03:47Who said cheese?
0:03:49 > 0:03:50Did you take a picture of me
0:03:50 > 0:03:51when I was asleep?
0:03:51 > 0:03:54Oh, what are these cobwebs?
0:03:54 > 0:03:55Who's your man with
0:03:55 > 0:03:56the big eyes there?
0:03:56 > 0:03:57What's he doing?
0:03:57 > 0:03:59Colin. Colin, where are my shoes?
