You're about to listen to a BBC podcast and maybe it's when I had a hand in.

I'm Tammy Walker and I produce podcasts for the BBC.

My role is to give new and diverse creators a voice with the opportunity to build a career.

That's the thing I love about podcasts.

You start with just a good idea, but then you have the space to see where it goes.

And doing that at the BBC means we can really run with the best stories

while developing the most unique audio talent.

So if you like what you hear, why not check out the huge range of podcast we've got on BBC

Sounds? I'd listen to the today program when I'm falling asleep at night and so I just had it on while I was lying going to sleep and it's had the

weather forecast and it said that it was raining.

Meet Eleanor. She listens to radio from the UK but lives in New Zealand.

And then I was listening out my window and I could hear it was also raining. I thought, oh yeah, it's raining.

I went, no, wait a second, it's raining

really, really far away in London and it's raining in Auckland. I thought, wait a second, do those raindrops, how long did they actually

come over to these, and did they actually come over to you see then? Do they travel the world or do we just have like the rain from our local area?

I just wondered if there is there a movement from all the way up in London to all the way down in Auckland or or not.

And if there is how long it would take.

This is crowd science from the BBC World Service.

I'm Caroline Steele and I love questions like this. So does

Eleanor. She's a science teacher so she's used to answering all sorts of weird and

wonderful questions from her students. But this time, thanks to the rain outside her window, it's her turn.

I was wondering how long a water droplets from London would take to travel all the way to New Zealand and drop his rain here.
