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

I'm Anand Jagatier and I'm trying to make a fire using some wood and a bow.

You need to be pressing down.

Deborah can you introduce yourself? I'm Deborah Fletcher. It's working. I'm a wilderness skills teacher and you're doing really well actually. The disc will want to ping out, so you need to keep that horizontal.

Deborah's teaching me the bow drill technique, which is at least 6,000 years old.

You twist a bit of wood around the string of a bow

and hold the string as well.

No, you can hold onto the string if you feel like it makes it tighter.

And saw it back and forth to generate friction and heat.

You need everything to get really warmed up.

Normally if you're a first timer the wood pings out of the boat and you have to start all over again.
