[Coop and Dino singing]

00:13

Welcome to the Patent Office of Ancient Inventions, where a record is kept of every important [Records of patents]

00:18

discovery in the history of mankind!

00:21

Today, we’re taking a tour of eight ancient inventions that changed how we live.

00:25

And no, we won't be covering Siri in this tour. [Mom and daughter using smartphone]

00:28

Sorry to burst your bubble.

00:29

We begin with the invention that helps make almost all other inventions possible: writing.

00:34

After years and years of frustrating trips to the grocery store … [Woman holding grocery bag]

00:37

… the Mesopotamians invented writing.

00:39

Thanks to writing, people were now able to record their history and keep records of work,

00:44

trade and family.

00:45

And, of course, make shopping lists easy to decipher.

00:48

It’s because of writing that people can communicate ideas across time and space.

00:52

Pretty nifty, eh? [Man and woman out shopping for groceries]

00:53

Of course, once you start writing, you need something to write on, which leads us to:

00:58

Paper.

00:59

Before paper, people wrote on stone and clay tablets, which were hard to store and move.

01:03

Seriously, you should've seen the paperboys back then…they were ripped. [Man throws stone onto stoop]

01:08

But all that changed in 100 BC, with the Chinese invention of paper.

01:12

And once paper was invented, ideas were able to quickly travel, allowing them to spread [Paper airplanes moving around a map]

01:16

to far off places with ease.

01:19

Further back in the Ps, we come to: the plow.

01:22

Apparently people in ancient Mesopotamia had a bunch of good ideas…must've been something

01:25

in the water…because it was a Mesopotamian farmer who invented the plow. [Farmer plowing in the field]

01:29

The plow allowed more planting to be done by fewer people.

01:32

That meant more opportunities for people to devote themselves to jobs like construction

01:36

and teaching.

01:37

It also meant more food. [Construction worker and teacher appear in the farmers field]

01:38

We're assuming sweatpants with elastic waistbands were invented soon after.

01:42

Those are a go-to at our Thanksgiving dinners.

01:44

Lastly in the Ps, we have Plumbing and Sewers.

01:47

Ha… speaking of “pee”, right?

01:49

Anyway, we’re back in ancient Mesopotamia, again –

01:52

--but this time, things were a little stinky.

01:54

So, they invented plumbing and sewers, which brought fresh water in and washed dirty water away. [Person drawing up sewer and plumbing designs]

01:58

This helped improve the health of populations living in cities.

02:01

Of course, now that the dirty atmosphere smell was gone, there was the small issue of being

02:05

able to smell each other…

02:06

Next up: The Lever.

02:08

The Greeks invented the ancient lever, which paved the way for many basic tools we use [Greek man stood beside pillars]

02:12

today, such as scissors, pliers, and tongs.

02:14

They’re all based on the idea a lever pivoting on a fulcrum to move a load.

02:19

If you've ever had a blast on a see-saw, you have a lever to thank! [Arrow points to see-saw]

02:22

…Seriously, go write it a thank you card.

02:24

They really appreciate the gesture. [Girl writing a thank you card]

02:25

Okay, card done?

02:27

Cool.

02:27

Let’s talk numbers.

02:28

Specifically: Zero.

02:29

Counting wasn’t getting very far in ancient Babylonia.

02:32

Literally.

02:32

Then someone invented zero, and everything changed.

02:35

Zero acts as a place holder when we get beyond nine.

02:39

And it allows us to count in the thousands, millions, and beyond. [Coop discussing invention of zero]

02:43

Which might have led to some people suddenly realizing they were rich.

02:46

Numbers are all well and good, but what about construction?

02:49

Well, that got a boost with the invention of concrete and cement!

02:52

The invention of hydraulic cement changed construction for good.

02:55

Oh, and in case you're not super up to date on your cement types, hydraulic cement gets [Man carrying bag of cement]

03:00

hard with the addition of water.

03:02

Thanks to cement, people could build taller and stronger structures than ever before.

03:07

And it was easier to transport than stone [Man stood beside the Colosseum]

03:08

Okeydoke, we’re almost through our inventions.

03:11

We saved the most organized for last…yup, it's our old buddy, Alphabetical Order.

03:16

We have ancient Egyptians to thank for this invention.

03:18

Alphabetical order makes it easier to organize information and find it again.

03:22

Not to mention, it provides a nice decoration for every classroom ever. [Alphabet decoration]

03:25

Phew!

03:26

That concludes our tour of ancient inventions.

03:28

Makes you wonder, what modern invention will future generations thank us for…? [Man stood with modern inventions]

03:32

…On second though, maybe we shouldn't think about that too hard…
