This episode of "Hard Science" is brought you
by Full Sail University.
Hey.
Welcome to "Hard Science," a show
where we use just a little bit of knowledge
about the world to bend it to our whim.
I'm Anthony.
I'm Tara.
I'm Trisha.
Trisha is on loan to us from SourceFed.
We promised Phil that we wouldn't
injure her or burn her or hurt her.
I'm so happy to be on this show.
You were a good kid growing up, huh?
Super good kid, yeah.
Like super nerdy, like mathletes,
all that kind of stuff.
Wow.
Me too.
Oh my god.
We were wondering if there was a way for good, honest kids
to fool their senses into feeling like they were high.
To get a good, honest high.
Just a good, honest high after a good, honest day of American
work.
Mm-hmm.
So how can we do that?
What's that way?
Oh.
Science, right?
This is my part.
That's what she does.
Great.
Senses are an organism's physiological capacity
that provide data for perceptions, the stuff
inside of us that lets us experience the stuff
outside of us.
And the nervous system has a different sensory system
or organ for every sense.
Aristotle is the man originally credited
with classifying the traditional five senses, sight, smell,
taste, touch, and hearing.
It's not dangerous.
Just keep doing it.
He's good at this game.
Yeah.
In addition to those traditional five senses
that we all learn in grade school,
there are actually additional senses
that control things like temperature and balance
and pain and some internal stuff that's
really cool like breathing and some internal stuff
that's not cool like vomiting.
[HIGH FIVING]
Was that a high five for vomiting?
Yeah.
Wait.
No.
So our knowledge of the outside world
depends on these various modes of perception.
Which is why it's really messed up
that they're super easy to fool.
Keep spinning, Trish.
We'll tell you when.
Got it.
Come near me, bitches.
All right.
Touch-- arguably the best sense of all.
Today, we are going to be doing something called the Rubber
Hand Illusion, and this plays around
with the sense of proprioception,
which is the thing that allows you to distinguish
your physical self from the rest of the outside world.
We have this board set up here.
You are going to put your hand on one side of it.
And on the other side we are going
to drape this over this hand.
And then we're going to do some things to the hand.
And what's going to happen is your brain
is going to start to associate that hand with your body,
and you're actually going to feel
things that aren't even happening.
Shut up.
Yes.
I want you to keep your eyes focused on this hand
the entire time.
I'm just going to start tapping you a little bit.
We're going to use the paintbrushes now.
Just continue to stare at it.
OK.
I am.
Oh, god.
That was so weird.
I'm so glad I aimed right.
Yes.
I feel something right here.
You do?
Yeah.
Yeah.
It's so weird.
Basically, what happens is when you detect discrepancies
between what you're seeing and what you're feeling,
the visual part of your brain sort of takes over
and it starts to associate the things that aren't actually
happening to you with your actual hands.
So what we have here is the miracle berry,
the miracle fruit.
This is from a berry from West Africa that has a protein in it
that they discovered in the '60s that they called miraculin.
And the reason why they called it miraculin
is it is a miracle protein that activates the sweet receptors
on your tongue for everything and then deactivates
all the other receptors--
Wow.
--for about a half hour.
Well, here we go, America.
See how you feel in 10 minutes.
Ready?
One, two, three.
Oh, that's so good.
It tastes like straight up lemonade.
Grapefruit is my most hated of all citrus.
Really?
What?
Ah, dude, it's just this sour, bitter thing for grandmas.
Oh.
It's awesome.
Mmmm.
Except today.
Except today where it tastes like watermelon.
You guys have no idea how much I hate tomatos.
One, two, three.
I'm sorry.
I'm sorry.
And it still has a tomato aftertaste.
I know--
It has the tomato aftertaste.
How does anybody like these?
Wash that down with a little vinegar, right?
Yeah.
Mmmm.
Balsamic vinegar.
Cheers, guys.
To your health.
Yeah.
That's pretty good, actually.
No.
No.
My mouth is telling me I'm eating nothing but candy,
but my stomach is letting me know what I've been eating.
Yeah.
I don't think this thing makes you love foods
that you already hate.
Fruit--
I think is what it works best with.
We all should've seen that coming.
Miracle fruit for other fruit.
Yeah.
My mouth is so high right now.
All right.
So let's talk sight.
Sometimes when you look at something,
it's not exactly expressing what's in actual reality.
So if you look at, say, a 2D drawing, and it appears 3D,
that's called perspectival anamorphosis.
So that's what we're going to play with today.
So everybody take a piece of paper and a pen--
Yay, coloring.
--and trace your hand, like we're
making a turkey on Thanksgiving.
OK.
Boom.
Boom.
That's a good hand.
Pick up a marker, and we're going
to draw on our anamorphic drawings
a straight line across.
And when you get to the outline of your hand, we go a hump.
Now we're going to continue making those lines
until the entire page is covered.
Oooh.
Look at yours.
You can pick another color and just
trace right underneath all your lines, exactly the same
but in a different color.
So everyone hold up your anamorphic drawing.
And now we know that these are only two dimensional,
but when you look at them from a certain perspective,
our eyes will trick us into thinking
that we're something 3D.
All thanks to the sense of sight.
Thanks, sight.
Well, thank you for volunteering--
Any time.
--to potentially injure yourself.
Yay.
Where can people find you elsewhere on the internet?
If you guys want to find me, I'm on YouTube.com/sourcefed
and YouTube.com/sourcefednerd.
And we have programming seven days a week there.
Or you can hit me up on Twitter @thatgrltrish,
no I in the girl.
There you go.
And the people who helped us get Trish here
to be hit with hammers, Full Sail University.
So if you enjoyed watching Trish get hit with hammers,
maybe that's the school for you.
Yes.
Exactly.
They've got a wide variety of anything related
to tech bachelor programs you want.
They offer courses online and at the actual school.
And if you go to the school, they
will provide all of the tech and stuff
that you need at a deep institutional discount.
Yup.
And so if you want to help out the show,
you can go to FullSail.edu/hardscience.
Now I'm going to start caressing, just like that.
Right there.
That's the sweet spot.
How's that feel for you?
Pretty good.
Thanks.
Pretty weird.
Hold on.
No.
Oh.
Sorry.
