The double trouble society and the worst curse is the new spellbinding mystery book

Hello, welcome along to a brand new episode of The Fun Kids Science Weekly.

My name is Dan. We've got a very busy show for you this week, which makes sense.

When you think this searches out all the secrets lurking in the universe, the universe is quite a big place.

So we should be jam-packed every week. This time you can hear about one of the strangest elements in the periodic table.

We've got the Prime Minister of the UK on the Fun Kids Science Weekly.

Boris Johnson will be on to tell us all about COP26, the big climate meeting.

He'll answer some of your science questions as well. That's coming up.

This week they're on teeth, on the solar system and on tsunamis.

That's on the way first. Let's catch up with one of the smartest geniuses ever telling us about some even smarter people.
