Oh, cool.
What is it?
It looks just like a bucket.
It is a bucket, and inside it's a worm farm.
I don't remember Old MacDonald having any worms.
[laughs] Look, gardeners farm worms in tubs, buckets, and boxes, with layers of food scraps and soil inside, because worms are great for gardens.
How come?
Ah, good question.
Nij, can you help us find out why worms are so good for our gardens?
Sure.
Sometimes on Imagine This we use our imaginations to shrink ourselves to see things better up close.
We could imagine ourselves as worm-sized.
Hmm.
I have another idea.
Is that compost in your pocket?
Classic Costa.
A sprinkle here, a sprinkle there, makes the real world disappear.
All it touches will grow tall, and you will seem so very small.
Whoa.
Whoa.
I think my imagination's playing tricks on me.
Me too.
The worm farm is growing.
And growing.
And growing.
