- Hi, I'm Sarah.
- I'm Inga.
- And we're not scientists.
- We are definitely not scientists.
- But we look like them today,
because we are going to be trying kids science experiments
as adults, yes.
Did you do a lot of science experiments as a kid?
- I am not familiar with the language of science.
I took chemistry once and I failed it.
I like actually failed it.
- I actually hated chemistry as well.
Oh, no, and this is kind of like chemistry.
- This is exactly what my nightmares
are made of. - Oh, no.
(screaming)
Anyway, Inga's here, I'm challenging her.
We're gonna see who can do the science experiment correctly.
And then, if all else fails, we're bringing in an expert.
Okay?
- [Woman] So, I consulted with someone via email,
who gave us the ingredients we'd need to build a volcano
without instructions.
- You're gonna need dish soap, white vinegar, food coloring,
baking soda, cold water, room temperature water,
an empty soda bottle, and, of course, a homemade volcano.
- But this is a competition, and we can't see each other,
so we're gonna need to--
- Block us off.
- Yeah, can we get a separation, please?
- This is a competition to fail less miserably.
That's the real competition that's happening.
- So this is in place?
All that I know is that the explosion happens at the end,
so there must be one ingredient that causes the explosion.
- Okay, and we only get one shot!
And I can't look at my phone.
- Don't look at your phone.
Inga, are you ready?
- No, but--
- Let's go.
(upbeat music)
- I don't really know why we have so many measuring tools.
Why does it matter if I don't actually know
how much I'm gonna measure in?
Aw, should I keep this for aesthetic purposes?
Why are there two different types of water?
- I feel confident that the water is not what's gonna
make the explosion, so I'm gonna put the water
in the bottle first.
- 'Cause I cook a lot, right?
So I know that for cleaning,
you combine these two ingredients.
So I know there's like some reaction going on here.
- I just heard her say you combine two ingredients,
I don't know which ones they are.
- So, I'm gonna add this in.
I don't know how much.
I hope this doesn't like actually explode.
Now what?
The water temperature has to matter.
Oh, no!
I don't think this is right.
- We're making a volcano,
so I think I got to put red in there.
- Oh, wow, that's a lot of water.
Is that too much water?
How much water are we supposed to add?
But this is gonna be my last thing.
Should I test it out?
- You're gonna do a mini one before this?
- And here, again, I don't know how much.
- I'm gonna add baking soda.
- How much do I need?
Is that gonna do anything?
Yo!
- What? - Nothing!
- Inga, did you just do it?
- Nothing happened, but I think I know
what (mumbles) to get it up! - Oh!
- All right, so this is gonna go in here.
- I feel like Inga's ahead of me now,
and I don't know how to deal with it.
It's the only thing I haven't added.
Kinda freeballing.
- I'm not even measuring.
- I just don't know what else to do.
We're doing it!
- One, two, okay, go!
- Oh, okay.
Okay, you can't see, but look.
It's--
It's fizzing.
It's orange.
Maybe it's like a soda bottle, and you need to kind of...
There we go, look at that!
Now it's looking good, just need to--
- It's so... - Oh!
- Pretty! - I just lost!
Oh, okay, all right, we can take this divider away.
- Was this supposed to shoot up?
I don't know what it's supposed to look like.
- Well, yours is doing way better than mine.
You think your cooking expertise helped you
figure this one out? - I think it helped a little,
'cause I knew that these two together.
I was saying that like sometimes I use this mixture
to scrub pots and pans.
And I know I get like some frothiness.
And I also know dish soap gives you bubbles,
so I just combined it.
I didn't know how much, though!
I just literally--
- What was the last thing you added?
- Vinegar!
- Okay, I did that, too, it didn't work out for me.
I must have had my measurements wrong.
- I think it could be better still, right?
- It could be a little better.
Let's clean this up, and let's bring in the expert,
all right? - I'm excited.
- Okay, high five.
- Yay!
- So, obviously, we couldn't really do this.
So, we're bringing in a science expert.
- A true professional.
- Hi.
- [Inga] Did you make this?
- [Marisol] Mhm.
- [Sarah] I'm sorry, how old are you?
- I'm nine, almost 10.
- I thought we were having a science expert.
- I am the science expert.
I've done so many volcanoes.
- [Sarah] Oh.
- Wait, how many?
- 23.
- That's more than the one I've made.
- This is my homemade volcano.
I actually painted it a couple days ago.
- This looks incredible.
- This is made of styrofoam,
but you can also use paper mache, dirt.
Just don't use paper, that's--
Just don't.
- Yeah, of course, we would never.
That would look lame.
Marisol, what's a volcano?
- A volcano is a cone-shaped mountain with a vent
that connects to the molten rock layer below the Earth.
When a volcano erupts, the molten rock is driven up by gas.
- Oh, okay, that makes sense.
So, that's basically what we're creating here.
- But this is different than an actual volcano,
you know that, right?
- Yeah, I know that.
Of course.
I'm an adult.
- [Inga] I've never been this excited!
- Let's get started?
- Yeah.
First, combine the water, white vinegar, dish soap,
and food coloring into an empty soda bottle.
I'm gonna measure out 400 milliliters of white vinegar.
- It's the adult thing I can do.
- Probably the only one you can do.
- [Sarah] Sounds like pee.
- Now that smells horrible.
Now, we're going to measure 100 milliliters of cold water,
and you need to add dish soap.
You need 10 milliliters of dish soap.
- Mmmmmm.
I mean, I don't eat dish soap, I don't know why I said--
- I hope not.
Now, add your food coloring.
Boop.
In a separate cup, to make baking soda slurry,
combine water and baking soda.
- [Sarah] Baking soda slurry. - Slurry.
- [Sarah] Did you make yours into a slurry?
- Did I make mine into a slurry?
Was that a slurry?
- Well...
- You need 50 milliliters of water.
It's going to be the room temperature water.
And then you add the baking soda.
50 milliliters.
- Does it react yet?
No.
- No.
Now we mix it around to make sure it's a slurry.
It's like paste.
- Mmmm, yummy paste.
- Can you explain the chemical reaction to me?
Like what's going on?
- Baking soda and vinegar create a gas
called carbon dioxide, and when mixed it foams and explodes.
- And explodes. - And explodes.
- That makes sense.
- Now it's almost time to do the experiment, but first,
we need to set up the volcano.
- Oh, I don't know why we didn't think of this.
- [Marisol] Don't wanna be messy.
- Yeah, of course.
Of course you don't wanna be messy.
I feel like I should put some dinosaurs out.
This is cute, huh?
Okay. - Sure.
I'm gonna make this slurry a bit more fun.
I'm gonna add some food coloring.
This is a very important step,
because you want the slurry to be very mixed.
Isn't that a nice color?
- It is, I like it, it's very pretty.
- Finally, pour the baking soda slurry into the soda bottle,
and step back quickly.
(laughs)
- [Sarah] It actually worked!
- Yeah.
It worked 23 other times that I did it.
- Okay, all right. - Okay, okay.
Well, I'm so sad I couldn't get it to do that
when I tried it.
Now we can do it, and you can do it at home.
- You can't do it.
- [Sarah] You don't think I can do it?
What about Inga, can she do it?
- Sure.
- Thank you.
- You were right, you had to jump back.
That's pretty fun.
We'll see you next time when we try
another kids science experiment,
and I guess get shown up by a kid.
How old are you again?
- Nine, turning 10.
- Nine, oh my.
- And already so wise.
What are we doing?
What are we doing? - [Sarah] All ready so wise.
Bye.
