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.
