- Hello, everybody, I'm Doctor Mike, and that's...
- Ari. - How old are you, Ari?
- I'm 11.
- I'm 29, so we're basically the same age.
I also want to introduce my special friend
who you may not have seen is back, look at this guy!
Speak.
(barks)
Good boy, and he just slobbered all over my face.
Today, we're gonna be doing Disgusting Science.
I wanna know why feet stink. - Making fake snot.
- And?
- That's in Spanish.
- That is in Spanish.
Can you translate the sentence,
"I have a dog named Bear" in Russian?
(speaks Russian)
He said he wants poop.
It's the grossest, most revolting science kit out there.
Grow your own friendly germs and fuzzy mold,
mix up a batch of coagulating fake blood.
It says learn science in a disgusting new way.
- No doubt, okay.
- If you've watched my channel, you're gonna know
the answer to this question.
Where do I tell everyone that watches my channel
to never put these?
- In your butt.
- Where do most people put these?
- Their butt.
- I feel like we shouldn't have a dog here,
it's like a biohazard.
You need a slice of bread, you need vinegar,
I don't think I have any bread.
Do you have bread? - You don't have bread?
- No, why, do you eat bread?
- I don't eat it, I use it for sandwiches.
- So you do eat it.
- Yeah.
- All right, you wanna do the sickening slimy snot?
- Sickening slimy snot that looks so real,
you might just want to barf.
- First we have to do is measure one tablespoon
of water into the bowl and microwave it for 15 seconds.
- Okay, this is a teaspoon, so how many
tablespoons are in a teaspoon?
- Strike that, reverse it.
- Okay, so that's one teaspoon,
that's two teaspoons, three teaspoons.
15 seconds in the microwave, let's go.
On the bottom of the microwave, on the touchpad,
Bear! Do you see why you don't
want dogs around science experiments?
- Okay, remove from the microwave,
well I think we did that.
Add one drop of green coloring to the water
and stir to...
- Dilute.
- Dilute, I knew that.
- [Mike] The suspense is killing me.
- I think it goes by itself, you know?
Okay, you're not patient, okay.
- By the way this is a great way to stir it,
if you just wanna stir something, you can just do this.
- Yeah, like wine.
- Why do you know that?
One tablespoon?
- [Ari] Yeah, so then.
- [Mike] You sure one tablespoon,
that sounds like way too much.
Try that and let's see what happens.
Maybe that is a tablespoon, not a teaspoon,
and we messed up.
- More like you messed up.
- We're a team.
I feel like we're making such a mess,
we're the worst scientists ever.
Ari, you have to do better when you're in med school.
- Why would I be in med school?
- Why, you don't wanna go? - [Ari] And three.
- [Mike] Okay.
Aw, it smells, smell it.
- OH!
Maybe it's just your water.
- What?
- You might have really bad water.
Let's just keep going before I throw up.
- What's the learning objective in this?
It says digestive science secrets.
- Your nose is lined with a mucus membrane that makes mucus.
- Okay.
- Mucus is the scientific term for snot.
Its sickness helps trap dust and dirt particles
in the air you breath.
Without mucus, your lungs would eventually get clogged
with dust and lots of dirty gunk.
- Okay, so can I put some of this on your face?
Just a little bit!
- Okay, first let's scoop it out.
If you put it right next to my nose, I'm gonna throw up.
- No you're not. A little bit, just a little bit.
- I wanna put it on Bear, he's used to it.
Get a napkin, I'm gonna throw up.
- Oh, it's so slimy.
Aw, and it smells!
- No, get that thing off me!
- Do I have any?
- I don't know.
- Look at my face!
- No!
- Aw, why do we need bread for everything?
Should I just knock on all my neighbors' doors,
hey, do you have bread?
Yo, yo, are you home?
Do you have a piece of bread?
Nothing, no any kind, I need it for a science experiment.
Yo, we gotta get that bread, son!
You got cash bread!
We just got some bread.
Let's do disgusting digestion.
- Kay, we need the balloon.
- Balloon, check!
No, why are you touching my balloon?
- We need vinegar.
- We need vinegar?
Tell me a fun fact about you while we wait for our plate.
- I can tell you what I wanna be grow up.
- What do you wanna be when you grow up?
- Teacher.
- What kind of teacher?
- I'm not sure, that's why I'm trying to figure out
what's my favorite subject.
- But why do you like teaching?
- Because you get to make an impact on people.
- You can make an impact doing many jobs, why that one?
- Because of Boy Meets World and Mr. Feeny.
- I wonder if these guys even know what that is.
- Or Malcolm in the Middle, Saved by the Bell.
- This kid is stuck in the 90s.
How many breads do we need.
- Breads?
It says a slice of bread, so one.
- What else?
- Pour some cooking oil.
- Where?
- In the thing!
- In here?
- Yeah.
- That's hard.
- And he's somehow a doctor.
You have to rub it inside.
Take some bread from the center of the slice
and break it up into small pieces.
- Why are you putting it here?
- No, that's a seed.
- You're a seed.
(faux crying)
- The small things always count.
Stuff the small pieces into the stomach.
- So stuff the small pieces into...
- The balloon.
How much pieces do we need?
- I don't know, just throw a bunch of them,
here, put some in here.
- Add a few drops of vinegar into the balloon.
My favorite number's 19, so I remember 19.
It said a few drops enough.
- Okay, we put a lot of bread in.
All right, so so far this is pretty accurate,
you have your stomach, you eat the food,
the food goes into the stomach, the acid is the vinegar,
it all mixes in cause the stomach mixes it up,
here, you squeeze it up.
- Tell me more, tell me more.
- You kinda smell singing Grease songs.
I'm gonna put you on some good music,
who's your favorite musician? - How am I supposed to know?
Continue squeezing hand over hand.
As you do this, the stuff inside will ooze out
the opening and onto the plate.
- Oh, I get it.
Ugh!
Look at that.
The intestine has muscle in it,
and the muscle rhythmically contracts like this,
as your fingers are, and as it contracts
it pushes the food forward and forward and forward.
- Which is now comes into poop.
- And then it ends up being poop.
And you see how it's on my fingers now?
- Wanna eat it?
- No, I'm gonna spread it.
The stomach has acid in it, it has food in it,
it mixes it up, and then when it goes into the intestine,
the muscles, through peristalsis,
push the food along and then it comes out.
- And some parts of your stomach are still uber tasty.
- Do you wanna see another experiment?
I wanna see another experiment,
do you wanna see another experiment?
Blood and guts, what do we need?
Gelatin, check.
- [Ari] Red coloring packet.
- [Mike] Red coloring packet.
- Is that a packet?
- Yes.
Step one, water, half a cup?
- Yes, add one half of a cup of water
into a microwave-safe bowl.
Heat the water to boiling in a microwave oven.
Add one half tablespoon of gelatin.
- Okay, throw this in the microwave.
- Why me?
- [Mike] God...
- [Ari] Look, how is that my fault?
Perfect.
Wanna smell it.
- Put the food coloring in it.
One, two, three.
- We're totally not even following
the instructions at this point.
This actually looks kinda good, doesn't it?
It kinda looks like jam.
Let's do something fun out of this,
cause this is actually turning out pretty...
- Let's just take this off.
- No, let's do this, and try and decorate
our faces like we're injured.
Make me look like a boxer who just got beat up.
- I'm gonna do what I wanna do.
- No, no lipstick.
- You are my daughter.
We will now look upon ourselves.
- Okay, okay, okay, enough on my face.
- My hair!
- [Mike] No, it's not in your hair.
- It's on my...
- I like this, hold on, I'm giving you whiskers.
- Oh!
- He's dying, this turned out to be a huge failure,
but I hope you guys had fun with us.
- Here, wanna do some red.
- Did you have fun?
You look like you had fun, did you have fun?
Tell 'em if you had fun!
As always, say it, say it, stay happy and healthy!
- You got on my sweater!
