Oh, hello. You have chosen a BBC podcast, but before you listen to it, we thought you might

like our podcast too. You might. You might. It is called Sightracked with me, Nick Grimshaw.

And me, Annie Mack. And we talk about the week in music. All the news, all the cultural

happenings in the UK and beyond. And great guests. And it's on BBC Sounds. Yes, where you can

also enjoy lots of playlists, music mixes and

live radio, everything from my six music breakfast show to Radio 3 Unwind. But obviously start

with our podcast, sidetrack. Obviously. Obviously. So if you like music, listen on BBC Sounds.

On Monday, I was invited to watch some diggers remove hundreds of thousands of wet wipes

from a place called Wet Wipe Island in an otherwise beautiful part of Riverside West London.

It's an offer I couldn't refuse.

The disgusting mess was the result of many failures, but the big one being

the emerging trend of using wet wipes at all. No doubt they have been a lifesaver over the years,

especially to parents, but the plastic fibres in some designs meant they were much stronger than

any disposable product needed to be.

And years on from their first and only use,

I witnessed just how durable they can be, hanging off the teeth of mechanical excavators.

I'm Marnie Chasterton from the BBC World Service.

This is Unexpected Elements.

And I've moved away from stinky wet-wipe Island to the joys of the studio in Cardiff.

And joining me from the comfort of our studios, we have an international team of science journalists.

In Bengaluru, India, we have Ed Gent. Hello.

Hello, Namaskara.
