The video is being made. Until it arrives, here is what it will say (108 words, about 54 seconds):

Here's a cloth bag on a table. Something's inside, and you can't see in.

How can you find out what it is, without looking?

You shake the bag. It rattles.

You feel it through the cloth. It's hard, and it's bumpy.

You sniff. It smells salty, like the sea.

So what is it? A rock? A shell? A ball?

Now let's tip the bag out. Twenty things spill across the table.

What was rattling? And how would you put all twenty into tidy piles?

That's what this topic is about: finding out about things, describing them, and sorting them.

Okay, so are you ready to open the bag?
