Steve Spangler?
What's going on.
I never like to know what's happening.
I like to be surprised.
You'll be surprised.
But I understand that this book is fantastic,
and my nieces are going to love it.
Well, you're very, very nice.
I collaborated with the Smithsonian,
so that's not a bad idea.
No.
And we tried to put together 50 experiments that
are easy for parents to do at home or grandparents,
things using just simple things around the house,
because the goal is to try to get kids excited about science
and engineering.
Yes.
They're STEM jobs.
Look at this, this is so simple.
Here's what you need.
I started with vegetable oil.
Notice you're not even having to wear safety glasses, that's
how cool.
That's so amazing.
I know.
First time.
So here's a look.
So the water goes inside.
So this is water and oil.
So it's that simple.
Water's in the bottom.
Now it's more colorful if you put the food coloring.
So grab the food coloring here, throw some of that in there.
So I think that'll work.
So the food coloring doesn't color the oil--
Yeah.
If one drop is good, 50 is awesome.
So that's perfect.
And then, so you see, we've just used it Alka-Seltzer tablet.
So that's-- it's so simple.
So watch, I'm going to set this here.
Just scoop up the Alka-Seltzer tablets,
and then drop them into these glasses here.
One of each?
Yeah.
Just going to watch what happens.
See how it just starts to take off.
Yeah.
And the carbon dioxide brings a little bubbles up.
The bubbles will pop, and then it will work down.
So it's kind of like a do it yourself lava lamp.
Wow, that's very cool.
Isn't that cool?
Easy to do.
Thank you.
So that's the kind of stuff we put in the book.
It's that easy.
Yeah.
Simple, simple.
All right.
Here's the other thing I like is when
I'm trying to find a science demonstration,
I try to see the origin.
And I was wondering, who presented science experiments
like for entertainment purposes?
The Egyptians did.
And so they didn't use this same material,
but I'll show you what they did.
They would take colored sand, so here you go.
Take a look at this colored sand.
And then they would put colored sand in water,
and then magically be able to reach into the water
and pull out dry sand.
Because the Egyptians coated the water with beeswax.
Here, try that.
They go into here.
Just pour it in.
Oh yeah, the whole bowl is good.
All right, so that's a great idea.
I've never done that before.
And then, and then look at this.
So yeah, usually as a teacher I'm sparing.
So what you see, look at this.
It's hydrophobic.
So they cover it with something like Scotchgard.
So if you want to make your own at home,
you can take sand and then cover it
with this hydrophobic material.
Hydrophobic, water fearing.
And look at this, as you pull it back up again,
you get dry sand.
That's incredible.
Isn't that just amazing?
Yeah.
Very, very cool.
So here, here's this for you.
I'm not done.
OK, I'm sorry.
We'll continue to play.
OK, here you go.
So I was thinking, well, what else
could you cover that would be just kind of fun.
So what if somebody on your staff
was going to go to a fancy restaurant,
and they didn't want to get like messy?
So the person's waiting for you right now.
Oh, boy.
I know.
Isn't that funny?
I always wanted to do this.
So Andy.
Andy.
Here is this for you.
That's good.
Perfect.
OK.
Good?
Yeah.
OK so now watch.
So the cannons that are here, I've always
wanted put my slime in the cannons,
so I made a batch of slime in each of those,
and you have the button here.
So we coated his entire wardrobe with that special material.
So let's just see if it works.
So messy Andy is going to have a fancy dinner
and watch what happens.
Oh, Andy.
I love you so much.
Stop.
Here we go.
Just do it!
Go!
You said not to do.
Just do it!
You want me to do it now?
Go!
Please?
When?
Ow.
See, look at this.
The coat is beautiful.
You can spill on your pants, that's why--
hit him again.
OK.
Here we go.
Oh my God.
Oopsie.
Try it again.
But here, I was looking at this.
Just in case the cannons didn't fire, I got buckets of it.
Watch this.
What are you doing?
Isn't that fun?
Here, watch this.
Look at this, see?
He can be really--
I'm so sorry.
Are you OK?
OK.
It's a little slippery.
It's really slippery.
It's OK.
Are you OK?
I'm good.
Ellen, I'm sorry.
Sorry, Andy.
I'm never coming back to the show.
I know.
This is my last time.
Look at where his glasses are.
His glasses have completely come off.
Go to commercial.
Go to commercial?
Yes.
OK.
Steve has one more experiment after--
we'll go to commercial.
Don't move.
You're going to fall.
I can't move.
12 years ago on your show I showed you--
I was working on the self carving pumpkin.
See, because you carve a pumpkin.
But then who has the time to push the eyes out?
I mean, you don't have time to like--
that takes a lot of work.
So put on your safety glasses.
All right.
So instead-- like the last time I did it,
I had a torch or a match, like this.
And these don't work all the time,
and like I don't want you to have to wait.
So they showed me this thing.
It's an electric match.
The match is right there, and the wires
come around like this.
And if you push that button, which I know you'd like to do,
it sends electricity and it lights the match.
OK.
You should try that.
OK.
Do it now?
Seriously, it's OK.
Really?
Seriously ready?
See, so that's it.
Yep.
So I know that's not all that exciting.
But we put the match inside the pumpkin.
Oh.
OK.
So now there's nothing inside the pumpkin, as you can see,
except I'm going to put these little rocks that are down
here.
So this is called calcium carbide.
When you add-- miners used to use this.
They'd put this in their little mining thing, they're lamp,
and add some water and then light it,
and that's how they used light 100 some years ago.
Right, so this goes down in here.
And so now I'm going to pour the water inside like this.
Good.
And now here.
You should put these on.
OK.
Good.
And you're going to stand back there.
I'm going to put this on, and when
I tell you to cover your ears you should.
All right.
So here we go.
You hang onto this.
OK, when you push that button, I'll
tell you when, it should generate enough gas
to push the face out.
Ready?
3, 2, 1, push the button.
[BOOM]
How cool is that?
Wow.
Anything worth doing is worth over doing.
So because electric match, take a look at this.
So you see what we got here.
We had 20 pumpkins all carved.
Higginsworth carved all of these.
And Carly and Joel and Higgins are all going to help me.
There's a funnel on the top of each of them.
So we're going to go back there, we're
going to pour water into each one.
Then, that's going to generate the gas inside,
there's an electric match on this end and one on this end.
When I say go, you're going to hit
this one, which I'll say front row,
and you're going to hit that one.
Then I'm gonna say back row, and you're going to hit that one.
OK.
Got it.
Yep.
Yeah.
That's the best way to carve a pumpkin.
OK.
Here we go.
All right, so--
Do you need me back here?
You're going to stay right--
no, no, you stay right there.
All right.
I already got an Andy, I don't need you.
All right, so stay there.
All right?
So here we go.
All right.
You ready guys?
All right, so here's what we're going to do.
We're going to take our water, pour it
in, and work our way down.
Ready?
Go.
Pour it in.
Good.
So the water is it goes in is now starting the reaction.
Good.
It's bubbling inside.
Good.
And now the audience, when I tell you to cover your ears,
that's going to be a really good idea.
All right?
So we're going to come out here, and right now-- oh, thank you--
so right now all of the gas is being generated inside,
and it feels like it's pretty good.
So are you ready?
Little count down.
You're going to do that front row first.
3, 2, 1, front row.
1, 2, 3, back row!
That's the best way to carve a pumpkin.
That's fantastic.
I thought you'd like that.
Wow.
Steve's new book is called 10 Minute Science Experiments.
It's out now.
You're all going home get a copy of Steve's book.
