The opening of the video shows a rainbow stripes moving across the screen from left to right. A cloud shape pops into the coloured stripes containing an image of a green metal meat safe. The video title 'What Is This' is superimposed on the meat safe. A question mark bounces into position at the end of the text ('What Is This ?') and an eyeball rolls around in the dot forming the bottom of the question mark and winks. Upbeat music plays in the background. A swarm of question marks moves across and fills the frame.
Close up of Teddy, a puppet. In front of him on a black covered desk is a sandwich. Teddy is making eating noises. Angela the presenter, stands behind the desk. Between Angela and Teddy, on the desk, is a green metal box with a pattern of holes punched into it. Above Teddy in the top right corner of the frame is an animated television graphic. A spinning question mark appears on the television screen.
ANGELA: (to camera) What is this?
TEDDY: I' wooks ike a ig ox.
(Teddy continues eating his sandwich.)
ANGELA: Oh Teddy. Don't you know it's rude to speak with your mouth full?
TEDDY: Sorry, Angela. I said, 'It looks like a big box.' Is that hole on the front some kind of handle?
ANGELA: Let's see.
(Angela puts her finger in the round hole in the front of the box. A door creaks open.)
ANGELA: Oh, it's a handle that opens a door on the box.
TEDDY: The door is one whole side of the box. Is there anything inside?
(Pan of the interior of the box.)
ANGELA: I can see some shelves.
TEDDY: Shelves are good for storing things.
ANGELA: They are, Teddy. Can you tell what this is made from?
TEDDY: I think it's some kind of metal, and the sides of the box have got heaps of tiny little holes in them.
ANGELA: They make a kind of pattern, don't they? So, can you figure out what it is?
TEDDY: Some kind of cupboard, maybe? I've never seen anything quite like it before.
ANGELA: Well, that's not surprising, Teddy. It was used in the past for keeping food, particularly meat, fresh. It's called a meat safe.
(Teddy, Angela and the meat safe. As Angela places her hand on the meat safe, the word meat safe appears in the television screen graphic.)
TEDDY: For keeping meat safe from flies and insects or hungry animals.
(Sounds of flies buzzing, and animals roaring, howling.)
TEDDY: What about keeping sandwiches?
ANGELA: Why not?
TEDDY: Why not just put stuff in the fridge?
ANGELA: Well, If we lived somewhere that didn't have electricity, the meat safe would be a very good way to protect our food, including sandwiches, from spoiling.
TEDDY: So it's like a fridge?
ANGELA: Well, it's a bit like a fridge. But you might notice it doesn't run on electricity. In the past, when meat safes were used, people would put it somewhere around their house that was shaded and would get a bit of a breeze.
TEDDY: Would the breeze go through all those little holes?
ANGELA: Yes, Teddy.
(An animation of the evaporative process is shown in the television screen.)
ANGELA: And, if you also hung some wet cloth over the sides of the safe, as the breeze passed through the cloth and the holes, it would cool down the air inside it which could stop the food from spoiling as quickly.
(As Angela talks the animation appears full screen explaining evaporative cooling. Warm air is shown as red arrows flowing towards left side of the meat safe. A white cloth is draped over the meat safe and blue water droplets are shown above the cloth to indicate that the cloth is wet. Blue arrows exit the right side of the meat safe to represent cooler air. Text above blue arrows reads, '18-25 degrees cooler air!')
TEDDY: If I go swimming on a really hot day, when I get out of the water my skin feels very cold.
ANGELA: Even when the wind is warm, the air cools down as it passes through your wet swimmers.
TEDDY: Would the meat safe be cold enough to keep ice-cream too, Angela?
ANGELA: Hmm, what do you think, Teddy?
TEDDY: Aw maybe not. It would have to be freezing cold to keep ice-cream, wouldn't it?
ANGELA: I think you're right.
TEDDY: Can I have an ice-cream anyway?
ANGELA: How about you finish your sandwich first, and then we'll go and get an ice-cream.
Teddy resumes eating his sandwich. Eating sounds.
TEDDY: 'At ounds ike a ood eal.
ANGELA: I think he said, 'That sounds like a good deal'. I'd better go get some ice-cream for Teddy. It looks like he's nearly ready for it. Bye for now.
(Angela waves goodbye.)
TEDDY: (lifting his head from the sandwich) 'Ee ah.
