  • 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.
