Science 5: Lab Safety
If you're going to set foot inside a science lab, you'd better know all the safety rules. For example, entering the lab with fifty pounds of dynamite strapped to your chest is highly inadvisable.

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]
Thankfully, science labs have plenty of rules to keep your eyebrows right where they belong. [Rules written on a blackboard]
And we know what you're thinking: most rules are obvious. [Paper plane hits a girl in the face]
And we know you'll always be on your best behavior when in the lab, but hey - there's
no harm in a little refresher course! [Guy who threw the plane laughing, then he is a hit by a paper ball]
Trust us, you'd look super dumb without eyebrows.
This is for the best.
For starters, you should never enter a lab or start an experiment without permission. [Coop pointing at a blackboard]
Be sure you always listen to instructions..
…don't run or goof around...
…and be sure to always wear gloves, goggles, a coat or smock, and closed-toe shoes.
Which unfortunately means you can't wear your funky astronomy-themed flip-flops, no matter [Guy wearing space flip flops]
how “sciency” they look.
Oh, and if you have long hair, it needs to be tied back.
Hair plus flammable chemicals equals the worst hair day ever. [Two girls have their hair set on fire]
It's also super important to always read labels and follow the instructions carefully.
Imagine if you picked up and used acetaldehyde instead of the acetic acid….in front of [Hand picks up flask of acetaldehyde]
Oh, also you could make something blow up. [Boy drops the flask and an explosion goes off]
But seriously…super embarrassing.
And we know it goes without saying, but you really should resist the temptation to touch,
smell, or eat anything in the lab. [Dino pointing at a blackboard]
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]
become Captain Pukes-A-Lot, or Ms. Chemical-burns-on-her-tongue… you really shouldn't do this. [Guys faces goes green]
And whether or not you think you handled anything that could be considered dangerous, you should [Hands being washed]
always wash your hands when you're done.
Beyond getting rid of chemicals, it's just good hygiene.
Follow these rules – and any others outlined by your teacher – and your time in the lab
will be a piece of cake! [Teacher holding a cake]
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]
