Kid Vision Space Adventures senses in space.# Hi Kid Vision kids.

It's me, Miss Penny, and this season we are going to space.

The Kid# Vision kids and I continued our adventures at the Kennedy Space Center where we learned# about how space can affect our five senses.

Our senses help us understand the world around us.# They send messages to our brain so we know what's happening.

Humans have five senses.

Touch,# sight, hearing, smell, [music] and taste.

Our sense of touch helps us feel temperature,# texture, and pressure.

It tells us if something is soft, rough, hot, or cold.

Our sense of sight# helps us see colors and shapes and movement.

Our sense of hearing lets us listen to music,# hear people talking, and notice the sounds that are around us.

Our sense of smell helps us# detect scents in the air, like flowers blooming or cookies baking in the oven.

And our sense of# taste helps us enjoy flavors like sweet, salty, sour, or bitter.

All of these senses work together# with our brain to help us explore and understand the world.

But what happens when astronauts leave# Earth and travel to space?

Do their senses still work in the same way?

Let's start with a sense of# touch.

On Earth, we usually use our legs to move and our hands to hold things.

But there's very# little gravity in space.

So, astronauts float.

They use their hands and their sense of touch# to move and their legs to hold things.

My friend Audrey showed us an experiment to learn about# another one of our senses.

Do you think we'll be able to hear any sound in space?

No.

Why not?# We hear it now.

So, why can't we hear it in space?

Because [music] there's no what?

Air.

Okay.# There's no air in space.

Exactly.

Sound travels in waves.

All [music] right.

And they need those# air molecules in order to bounce off of in order to reach our ears.

That's the only reason you're# able to hear me right now.

And the only reason that you are able to hear, let's see if I can get# it.

This really loud ringing noise.

All right.

We're going to try to quickly put it in here.

All# right.

You can still hear it because there's still air in the chamber.

I haven't taken the air away.# Can everybody hear that high-pitched ringing?

All right.

We're going to now turn on our# vacuum and take away all of the air.

Okay.

And don't worry, I'll turn it off in just# a second so that you can hear or maybe not hear something very specific.

But as# we're taking away those air molecules, those sound waves have nothing to bounce# off of anymore.

So, let's turn it off.

Now, I still hear it.

You hear a vibration, but# do you hear that high-pitched ringing noise?

No.

That's the sound that's being taken away.

But# you can hear that vibration because of the hammer hitting the sides of the bell.

It's traveling# through our vacuum chamber, through the table, and up to our ears.

So air is very important for us.# Air is extremely Yeah.

Let's put the air back in.

There we go.

Can you hear it now?

Yeah.

Wow.# Our sense [music] of hearing is affected in space because sound needs air molecules to# bounce [music] off of.

No air, no sound.

When we go up into space, we experience# this thing called fluid shift or puffy head, bird leg.

It is exactly how it sounds.

It's when# all of the fluid that's kind of down towards our legs due to the gravity down here on Earth shifts# up towards our head when we [music] go up into space because there's no what in space?

Air.

Air# and gravity.

All right.

So all of that fluid is going to shift up towards our head and we're going# to experience this thing called puffy head which means we're going to get a really big head and# super tiny little skinny bird legs.

All right.

Yeah.

Now this affects just a couple of our# senses.

We're just going to talk about one today and that is our smell.

Now what happens when# there's a lot of kind [music] of liquid in our head?

Have you ever been sick before?

Yes.

Yeah.# What what do you get when you get sick?

A cold.

You get a cold and you get really congested.

So# that does affect a little bit of our smell.

Okay, we can't smell properly in space.

Now, don't# worry.

It will shift back over [music] time, but for the first couple of days, it's a little# bit of a problem due to the liquid and the fluid shift going up to [music] your head and causing# that congestion, which is causing uh that lack of smell.

Because whenever we get sick, we can't# smell things properly either, right?

So, when our astronauts go on a spacew walk, that's when# they go outside of the ISS to fix something on it, the molecules from space will [music] attach# to their big white fancy spacuits, right?

And when they come back into the International# Space [music] Station, there's going to be a lot of oxygen molecules that will attach to the# molecules on their space suits [music] and it'll change the pH balance.

It'll change the smell of# whatever they're smelling.

So, a lot of astronauts will say that they smell a burnt steak or a sweet# metallic kind of smell when the astronauts come back in from the spacew walk and that's what they# associate space to smell like.

All right.

Now, we do have what we call a space candle right here.# It's not going to smell like burnt steak because we wouldn't sell many of those if it did.

But it# does have that kind of sweet metallic smell.

So if you guys want to smell it, you can.

Do you think# that smells good or you think the astronaut sme?

It smells like soap.

It smells a lot like soap.# You want to smell it?

I would like to smell of course.

It smells like soap.

It smells# like soap.

It does smell a lot like soap.

But that's what happens with our senses in space.# Pretty cool, right?

Yeah.

Nice.

This fluid or puffy head bird leg syndrome can also affect an# astronaut's sense of sight.

Because more fluid moves towards the head, astronauts may notice# blurrier vision or trouble focusing.

[music] We talked to an astronaut named Captain Winston Scott# about what it's like to live in space, [music] and one of our Kid Vision kids had a great question.# books taste different in space.

That's a good question.

Do things taste different in space?

Yes.# Some things can taste different in space.

That's right.

You find that some food you like here# on Earth, you don't necessarily like in space.

Some things you don't like here, you'll like# in space.

Uh [music] your sense of taste kind of gets dull in space.

So, you find yourself# seasoning your food much more than you do down here so that you can get some flavor out of it.# So yes, foods can taste differently in space.

It was so interesting learning about the senses# in space.

We will learn more about our sense of taste and food in space on our next episode of# Kid Vision Space Adventures.

Bye.
