00:03

We know you're eager to get out there and start conquering the world with your...

00:06

your chemistry, but until you've learned a few basic safety precautions, you'll have to...

00:10

just keep your mitts off our beakers, so to speak. Having to learn about...

00:14

and avoid potentially lethal situations can be a real drag. But...

00:18

you may actually thank us once you've made it to the ripe old age of 22...

00:22

with all your limbs and eyeballs still intact. All right, so here's your safety...

00:26

checklist coming at ya. Number one: read and follow directions.

00:30

Directions aren't just there to look pretty. They can alert you to the possible...

00:34

safety hazards, and advise you how to properly handle dangerous...

00:38

chemicals. Here's Stan not reading the directions. Here's Stan...

00:42

combining nitric acid and hydrozine. And here's where Stan's...

00:46

hair used to be. Yeah, let's not be like Stan. Safety item...

00:50

numero dos. Protect those eyeballs. Unless you're a cyborg...

00:54

who can just go into mission headquarters to be fitted for a new pair of peepers,

00:58

those eyes of yours are the only ones you're ever gonna have. There are all...

01:01

kinds of noxious fumes and gases inside a chemistry lab, and if they find...

01:05

their way into your eyeholes, they're gonna cause permanent damage.

01:08

Any time you're working with materials you wouldn't want to go pouring...

01:12

all over your face, strap on a pair of lab goggles. This is Stan not wearing...

01:16

goggles. This is Stan getting a little too close to an alkaline...

01:20

chemical reaction, and this is Stan putting in his contacts.

01:24

Moving on: number three. Don't let your piggies out of their sty.

01:28

These shoes are awesome. For the beach. In a...

01:32

lab full of breakable glass, not so much. Guess who...

01:35

likes to wear flip-flops to chemistry class? Oh yeah, Stan. Good call.

01:39

Here's Stan dropping a flask. Here's Stan's piggy toes being cut...

01:43

into pork sausages. Stan's totally gonna wear sneakers next time...

01:47

if there is a next time. Safety rule number four: this is not...

01:51

time to let your hair done. Save it for your modeling shoot or...

01:55

something. In a chemistry lab, the idea is not to dangle flammable materials...

01:59

over open flames. If you do, then, like Stan, you might lose...

02:03

what's left of your hair. Poor Stan. Class pictures are tomorrow, too.

02:07

Number five: make sure the equipment you're using is in tip-top shape.

02:11

If your Bunsen Burner is out of whack, or your eye-dropper has more...

02:15

holes in it than a slice of swiss cheese, you may want to let your teacher know...

02:19

so you can get some replacement equipment that won't kill you.

02:23

If you notice that something is funky, but forge ahead anyway, well bad...

02:26

things are bound to happen. Just ask Stan. Not that he can really hear you...

02:30

right now. You might want to ask him in writing. Finally, number six: when in the..

02:34

lab, don't put anything in your mouth, ever. We can't stress this...

02:38

enough. We don't care how long it is until lunch, or how delicious you think...

02:42

that blob of melted lithium looks. Wait it out. You're wearing goggles...

02:46

for a reason. This stuff, and your body, do not mix.

02:50

Leave your leftovers for Stan. He'll finish them up for ya. Happy

02:54

picture day there, Stan.
