For today's at-home experiment,
we are going to learn the science
of non-Newtonian fluids
by making Oobleck.
Now, remember,
for you scientists at home,
make sure you grab a grown-up for help,
because all good scientists 
need good lab assistants,
and all kid scientists
need a grown-up's approval.
Now, to make Oobleck, you just need
a couple of basic things.
You need water,
you need some food coloring,
if you want to make it colorful, 
which we do,
and you need some cornstarch.
And to mix the two, you just need
one cup of water...
just like so.
We're gonna mix this in a bowl here.
I'm gonna add my food coloring.
And I'm gonna put some gloves on,
because I don't want get my hands 
all blue.
And then,
we want to add 
one to two parts cornstarch.
So we're just gonna add one cup for now,
and mix that in good.
Okay.
Using a spoon...
You'll notice, when you're mixing this up,
it's actually kind of hard to mix.
You notice the weirdness 
of non-Newtonian fluids right away.
There's not a really perfect recipe 
for this,
but we can take it with our hands...
Oh! All right.
Now, look at this. When you pass it 
back-and-forth, like a ball,
you're adding a lot of pressure,
so it acts very much like a solid.
[splats] 
It's very important
for you scientists at home,
when you're done making your Oobleck,
don't put it down the drain.
'Cause it will clog your drains.
Instead, put it in a plastic bag, 
tie it off, and throw it in the trash.
And this is how you make Oobleck.
How cool is that?
