This is the Fun Kid Science Weekly. My name's Dan. Thank you so much for giving us a listen.

It's the only show that takes you to the very deepest, the very darkest, and the very most dangerous corners of the universe.

I don't know if that's a sentence, but we'll roll with it. It's where we learn about all the secret stuff that's hidden away.

Now this week, we're chatting to the author and scientist Millie Marotta,

all about her, a brand new book, which looks at some of the most amazing and endangered species

on the planet. We'll also talk about one of the most dangerous plants that's out there in the

wild, not too wild either. There might be some of this in your back garden right now. I'm

being serious with that. You'll find out more in a sec. We'll also hear about a brand new planet that scientists think

may hold alien life. And I'll answer some of your questions. Today, they're about the sun and hearts.

It's all on the way. First, let's catch up with our favourite inventing genius. He'll tell us how some things are made.

This is Sir Sidney McSprocket.

How's it made?

Oh, hello, Sir Sidney McSprocket here.

I've been in action capturing facts all about manufacturing.

It's for this rather splendid stipendary compendium I'm compiling.

You just ask it how something is made, and it'll oblige with a fulsome explanation.

Like this, how are toothbrushes made?

Oh, doesn't look quite as simple as they look.

Toothbrushes are made of plastic, so that's where the process begins.

Step one.

Tiny granules of plastic are loaded into a huge steel pan called a vat to be melted to make a plastic

dough.
