00:13

Science labs are some of the most exciting places on earth. [Scientists working in a lab]

00:17

They are where vaccines are made, cures for diseases are discovered, and where the booger-flavored

00:22

jelly bean was invented! [Scientist pipetting liquids]

00:23

All equally important, of course.

00:25

But when you're working in a lab with a variety of substances, it's important to be super

00:29

careful.

00:30

One wrong move and you might suddenly be wondering where your eyebrows went. [An explosion goes off and man in a lab coat loses his eyebrows]

00:34

Thankfully, science labs have plenty of rules to keep your eyebrows right where they belong. [Rules written on a blackboard]

00:38

And we know what you're thinking: most rules are obvious. [Paper plane hits a girl in the face]

00:41

And we know you'll always be on your best behavior when in the lab, but hey - there's

00:46

no harm in a little refresher course! [Guy who threw the plane laughing, then he is a hit by a paper ball]

00:49

Trust us, you'd look super dumb without eyebrows.

00:51

This is for the best.

00:52

For starters, you should never enter a lab or start an experiment without permission. [Coop pointing at a blackboard]

00:57

Be sure you always listen to instructions..

00:59

…don't run or goof around...

01:01

…and be sure to always wear gloves, goggles, a coat or smock, and closed-toe shoes.

01:06

Which unfortunately means you can't wear your funky astronomy-themed flip-flops, no matter [Guy wearing space flip flops]

01:10

how “sciency” they look.

01:12

Oh, and if you have long hair, it needs to be tied back.

01:15

Hair plus flammable chemicals equals the worst hair day ever. [Two girls have their hair set on fire]

01:18

It's also super important to always read labels and follow the instructions carefully.

01:23

Imagine if you picked up and used acetaldehyde instead of the acetic acid….in front of [Hand picks up flask of acetaldehyde]

01:28

everyone.

01:29

How embarrassing!

01:30

Oh, also you could make something blow up. [Boy drops the flask and an explosion goes off]

01:32

But seriously…super embarrassing.

01:33

And we know it goes without saying, but you really should resist the temptation to touch,

01:39

smell, or eat anything in the lab. [Dino pointing at a blackboard]

01:41

We know you're trying to turn yourself into a superhero…but unless your dream is to [Guy opens chemistry lab door with a cape on]

01:44

become Captain Pukes-A-Lot, or Ms. Chemical-burns-on-her-tongue… you really shouldn't do this. [Guys faces goes green]

01:49

And whether or not you think you handled anything that could be considered dangerous, you should [Hands being washed]

01:54

always wash your hands when you're done.

01:56

Beyond getting rid of chemicals, it's just good hygiene.

01:58

Follow these rules – and any others outlined by your teacher – and your time in the lab

02:02

will be a piece of cake! [Teacher holding a cake]

02:04

But uh…don't try to make cake in lab…who knows what that stuff might be laced with…? [Student eats the cake and his face goes green and he falls over]
