[APPLAUSE]
I'm a huge fan.
No.
This guy--
Oh my gosh, I'm a huge fan.
I'm a huge fan of yours.
I've never met you before, so it's great to be here on a day
when you're here.
Thank you very much.
I have no idea what's about to happen.
This is a good thing.
OK.
11 years ago, Ellen was nice enough
to invite a science teacher from Englewood, Colorado
onto her show and so I brought the very first demo
I ever did with her.
I wanted to bring it for you.
Oh, that is so sweet.
Thank you.
I just, I learned how to do it better.
OK, good.
[LAUGHING]
Have you ever breathed helium?
I have.
Yeah.
[LAUGHING]
So since everybody's done that, I figured
wouldn't it be fun to breathe something
that's a little bit different than helium?
Wait, what are you about to--
OK.
So this is great.
So don't worry about the safety warnings, it's fine.
It's not mood altering, is it?
No, it's fine.
It's fine.
So this is a gas that's six times heavier than the air
we breathe.
It's six times heavier.
But it's not helium?
It's not helium.
It's a gas called sulfur hexafluoride.
Don't worry about it.
And hang on there.
It sounds safe.
It's safe, yeah, So hang on right there.
And this one will be mine.
So here's what's going to happen,
in just a second you're going to breathe all your air out
and I'm going to say, breathe all of this air in
and you're going to do it.
It's going to be great.
I feel like I'm asking way too few questions.
[LAUGHING]
It's fine.
So watch this.
You're going to breathe out, you're good to go [EXHALES]
and you're going to breathe all of this in.
Ready?
Now talk to the audience.
(DEEP VOICE) [INAUDIBLE] Oh, my god.
This is creepy.
[LAUGHING]
I know.
Isn't that great?
This is my-- oh.
[LAUGHING]
I know.
Isn't that great?
I've never had-- and it's almost over.
No, it's not.
[LAUGHING]
It's going to be that way for, like, six weeks.
[LAUGHING]
(DEEP VOICE) Isn't that the greatest sound ever?
It's unbelievable, this sulfur.
I know.
Breathe out.
Hello?
Breathe in.
Breathe out.
Oh my god, I had a baby.
No, I'm kidding.
[LAUGHING]
How fun is that?
Isn't that great?
You guys, I don't do drugs, that was the most exhilarating thing
I've ever done in my life.
[LAUGHING]
Well, if you like that then you're going to love this.
So these are safety glasses just because they say we have to.
So we put that on.
This is a special powder, it's a spore called lycopodium.
So if we just put a little pile here and now we
light it on fire.
Get ready to runaway.
Runaway?
Get ready to runaway?
No, see nothing happens.
See, I wouldn't do that to you.
OK.
So it's not flammable this way, but if you put it in the air
and you disperse it, that makes it cool.
So here's what I did, I made you a flamethrower.
I mean, an excitement maker.
[LAUGHING]
And so here's what you're going to do.
In just a second--
I'm not inhaling.
--you're going to hold on here.
And then, no, don't inhale.
[LAUGHING]
OK, and then you get to squeeze the trigger
and you're going to make the fire go on
and then you're going to blow out.
OK?
I really have way too much trust in you.
I don't know why I'm doing everything you're saying.
It's gonna be fine.
So sorry.
Tell me the sequence.
Hold on like this with me.
OK, squeeze, make fire.
OK, now blow.
Ready?
As the fires on?
Yeah.
OK.
So go, make fire, now blow.
Isn't that awesome?
Oh my gosh, that makes me feel powerful.
[APPLAUSE]
Come over here.
Honestly, all of this kind of stuff, this
is what we're trying to do is to get kids excited about science
so that one day they become a scientist and engineer.
That's what we try to do.
That's excellent.
That's a wonderful aim.
I wanted to do something that-- because bubbles aren't bad,
bubbles you're safe, right?
Well, I'm beginning to think they're not.
[LAUGHING]
They are.
So it's just going to make some bubbles.
And so normally you would just put the air in the bubbles,
but I have two tanks back here that are fun.
So this tank, for example, this is oxygen.
What could be bad about oxygen?
Oxygen is great.
Yeah, we need it.
So here we go.
Oh, that's good.
So this is our oxygen. Good.
So nothing's bad about oxygen. And then
the other tank has this gas, it's called hydrogen.
I know about hydrogen.
It sounds nice.
So this goes in here like that.
Stop it.
All right, so here we go.
Something--
Oh, good.
All right.
No, a little bit more, it's a big show.
All right, so now watch this.
This is two parts hydrogen, one part oxygen.
I know exactly what that is.
What is it?
Water.
Stem girl.
This is awesome.
H2O.
So you're going to like this.
Settle down.
[LAUGHING]
So put your glasses on.
OK, so in just a second here's what's going to happen,
I'm going to bubble that gas into the soapy water.
You're going to bubble the gas?
And then you're going to take your hands
and take the diamond off.
No, take both of them off.
I'm serious.
Yeah, just take them off.
Thief.
[LAUGHING]
It's fine.
So then, here's what you're going to do
is, you're going to scoop up the gas, the bubbles,
and I'm going to light them on fire.
Why would I let you do that?
The water is in my hand, you're going
to light my hands on fire?
Because Ellen said to do it.
All right.
I'm the guest.
[LAUGHING]
So that's what's going to happen.
In just a second I'm going to say to you, cover your ears.
And I'm serious.
You're going to cover your ears, all right?
You have to.
Should we cover our ears?
Oh, yeah.
That's a good idea.
This one's yours.
Good, so you can put that on.
And this one will be mine.
So I can sort of hear you.
I can't hear you at all.
So here we go.
You ready?
Get your hands wet.
Go in.
Good.
Now pull them back out.
OK.
So now, pull away, and now I'm going
to make bubbles here like this.
Oh, good.
Two parts hydrogen, one part oxygen.
Cover your ears, serious.
OK, now scoop up some bubbles, a lot of them.
Scoop them up.
Just scoop them up.
Just the bubbles?
A big scoop.
Yes, hold onto them.
Wait.
Now, hold on a second.
Don't let go, whatever you do.
Just stay right there.
Stay right there.
[SCREAMS]
[BANG]
[LAUGHING]
Not bad, huh?
[LAUGHING]
Look at that.
[APPLAUSE]
It's so terrifying.
This is for you.
Thank you.
I have something else for you when we come back, something
that we've supersized just for you.
One more experiment after the break.
You have one more experiment to show us?
I do.
So you know we're talking about gas.
You were nice enough to hold hydrogen and oxygen,
we made futuristic fuel.
This time I thought we would use a nitrogen,
the air that we breathe.
Meet Carly and Brian.
Hello.
And so Carly and Brian are going to fill the little bottles
that you see down there with nitrogen. It's my favorite gas,
but I like it as a liquid, so it's liquid nitrogen.
So 320 degrees below zero, that's
what that stuff is over there.
Cool.
You and I are going to do this.
So I have a bucket of hot water here.
So here's our hot water.
And this is just going to go in here.
So you can see where it's going inside.
See that?
Yeah.
So there's a little bit of hot water in this one, and this one
as well.
And then this one over here.
So the first time we ever did this on the show,
we did about 2000 ping pong balls.
We thought that would be fun.
So this time we got 15,000.
[LAUGHING]
Oh, my gosh.
That would be good.
So here's what's going to happen,
you are going to put your safety glasses on.
So what's going to happen is this--
oh, thanks Higgins, appreciate that.
Nice job.
Good.
And Carly's got hers?
Excellent.
We all doing well?
Excellent.
All right, so here we go.
So we're going to count--
don't try this at home.
[LAUGHING]
Good guys?
What's going to happen to them?
OK, you ready?
Let's cap it off.
All right, so we cap it off like this.
Good cap, nice and tight, nice and tight.
Good.
Now put it down inside.
Excellent.
And now let's put the ping pong balls on top.
There we go.
Good, Carly.
You're doing great.
Doing great.
Excellent.
So now, you and I stand--
[BANG] [BANG] [BANG]
[APPLAUSE]
Isn't that awesome?
That was awesome.
[APPLAUSE]
The gas pushed the ping pong balls out.
I've never done that.
That's so awesome.
That was so cool.
Oh, my gosh.
Wow.
That was very cool.
Go to Steve's website to learn more about Steve's Science
at Sea cruise to Alaska.
I want to thank Steve Spangler--
[APPLAUSE]
--Minnie Driver, and [INAUDIBLE] Young.
[APPLAUSE]
I'm giving you a hug.
Thank you so much.
My gosh, we got right over here and it was there.
It was mesmerizing.
It was such a spectacle.
Boom.
I loved it.
And by the way, Ellen has a brand new app
called Game of Games.
You can download it now for free.
I can take off my glasses now.
It seems safe.
Thank you so much, Ellen, for letting me guest host
and as Ellen says, be kind to one another.
Bye.
Hi, I'm Andy.
Ellen asked me to remind you to subscribe to her channel
so you can see more awesome videos.
Like videos of me getting scared or saying embarrassing things,
like ball peen hammer.
And also some videos of Ellen and other celebrities,
if you're into that sort of thing.
