I'm just gonna go for it.

Oh, it didn't get... I didn't add water!

- Hey, Inga?

- What's up?

- You ready to do another kid science experiment?

- I am ready.

(upbeat music)

- Have you heard of elephant toothpaste?

- I have only heard of it

because I saw this viral video

where this guy made one that was huge

and it just like-

- Yes.

- went up into the sky.

- Yes, it looks cool.

It's very fun.

The only problem is we don't have instructions

on how to make it.

We just have the ingredients.

So Inga and I are going to see

who can make elephant toothpaste.

Divide us.

- Do you know why it's called elephant toothpaste?

- It's just such a large amount of toothpaste.

It must be for an elephant.

(elephant trumpets)

- [Inga] No.

- I'm pretty sure there's no more logic to it than that.

- Okay.

- We're gonna have about 10 minutes to put this together.

- All right, let's do this.

(dramatic music)

- All right, I'm gonna put these on,

cause we're dealing with chemicals here.

- So we have some old friends here,

like this little guy and this-

- [Narrator] As Inga and I try to complete

this fifth grade science experiment.

- Oh wait, I don't want to do that yet.

- [Narrator] Actual kid experts

(mumbling)

are going to tell you how you actually

make elephant toothpaste.

- This is what you need.

- Hydrogen peroxide.

- Yeast.

- Dish soap.

- And food coloring.

- A little hot water.

- And then a flask.

First you need 240 milliliters of hydrogen peroxide.

- Okay so next 60 millimeters of dish soap.

(dramatic music)

- Oh, I didn't measure that.

- Pour the hydrogen peroxide, dish soap

and food coloring into the bottle.

One, two, three, four, five.

- I think the yeast is the rising agent.

- I don't cook really so I think yeast,

I think yeast infection.

- Next in a separate container.

- Now we're going to make 7.5 milliliters of active yeast

with a little hot water.

- And then give them a little time. At least 5 minutes.

(dance music)

- You know what? It smells like a beer.

- I feel like it's not activating the right way.

- They probably don't tell you that when you're a kid,

because they don't want you thinking about beer

as a fifth grader.

- Should I add more?

Okay. I'm just going to test this out.

I don't know if you can give me anything.

- You're doing a mini test right now?

- Yeah.

- Okay I'm going to do a mini test too.

- I just need more quantities of stuff.

- Wait.

- Wait. It's going up.

- It's slowly...

- That's a really good sign so...

- Are you about ready to do it?

- Yeah. I'm going to do the actual thing now.

- Finally pour the yeast mixture into the bottle

and then you got elephant toothpaste.

- Ready.

- And-

- Go!

- Go!

(screaming)

- Yeah!

That was like toothpaste. That was like a toothpaste right?

- You can keep adding color to it I think too.

- Oh wait really?

- Yeah.

- Wait this is the coolest thing ever.

Oh my God! Look at that you guys.

- Ah, man.

Honestly Inga, I feel like this is the closest to correct

I've gotten and it was mostly because you said the thing

about yeast stuff.

- Activated.

- So how does the chemical reaction

behind elephant toothpaste work?

- Well the hydrogen peroxide

that slowly breaks down into oxygen and water.

- And to make the reaction happen faster,

we add a catalyst; yeast.

- The oxygen gas turns into bubbles.

- And bubbles plus dish soap will make it foamy.

And that's how you make-

- [Both} Elephant Toothpaste.

- All right. Well, I think Ingo and I learned a lot.

So hopefully now

you guys can make elephant toothpaste at home.

Even if you're a dumb, dumb adult like us.

All right. Bye.

- Bye.
