Hello and welcome along. My name's Dan. It's a brand new Fun Kids Science midweekly, a bite-sized science special on a Wednesday.

Another chance for you to take a trip across the universe to discover all those secrets lurking through the solar system. This week,

have you ever wondered exactly how a phone works? We'll unpack it. Or maybe you're planning an

expedition around the sun. I've got you covered on that with five new questions to be answered.

Let's get to it. Lots of brilliant questions to get through this week.

So let's kick things off with Hugo. My name is Hugo. I'm six years old and this is my question.

Why don't really birds get stung when they're all stinging nettles? Thank you for this, Hugo.

We need to remember why stinging nettles sting.

It's a defence mechanism.

They've got these needle-like hairs that inject chemicals, toxic chemicals, into your skin.

Now, it's not really, stinging needles aren't really designed to try and get you,

Hugo. It's designed for predators that might want to eat the leaves. So it's their way of

defending themselves from getting munched on really. Now, the reason ladybirds can sit on

really easily, it's because they've got a very hard

exoskeleton. They've got like a shell around them. And very simply, the needle hairs that

jab you with the toxic chemicals that are mainly aimed at rabbits and deer, they can't break

through that skeleton so they can't hurt the ladybirds. So they do it really easily. They just sit

there, they mind their own business without getting poisoned. And it's very key to remember that

ladybirds don't want to eat stinging nettles.

They're not predators. So the nettles have got no reason to be worried by them. Instead,

they sit and wait for other insects that they can have for a snack. Thank you so much for

that question, Hugo. Let's get another one on the show. This one is
