Welcome along, Explorer. It's time for more out of this world discovering adventures in the Fun Kids Science midweekly.

My name's Dan, and it's all about the questions this week. If you ever have anything sciencey that you want answered, make sure you leave it as a voice note for me on the free fun

kids app and at funkidslive.com. That way you will start in the show. And I can get a genius on

to try and answer your question. I'll do it myself. We will get it sorted. All right. So voice

notes to the free fun kids app and at funkidslive.com. This week, we're talking moons, croaks and cars.

One nerve, the ocular motor nerve, which controls the eyelids, is stimulated.

It's fired up.

So, when your sneeze reflex fires, so does the signal that tells you to close your eyes or to blink.

So that's what's happening, but why is it happening?

Well, we've done this show long enough, haven't we, to understand that pretty much everything

that your body does has evolved to do that. Through hundreds of thousands of years of almost

biological trial and error, why you do what you do is because

there's a brilliant reason for it. So with closing your eyes when you're sneezing, it's not to

stop your eyes from bulging out and popping out. I know that's a myth that you might have heard.

It's thought that it's to stop whatever you're sneezing out
