00:07 This one here, and here… And here…
00:13 And… It’s done! IT’S DONE!
00:17 I have invented the time machine!
00:21 But do you know, one of mankind’s greatest inventions is probably lying around you right now?
00:28 That’s right my friend, PAPER!
00:32 This little thing is so abundant that it sometimes feels like a natural product.
00:38 But it isn’t quite so.
00:41 Ooooh oooh. Oh, no! There it goes…
00:47 Let’s trace this paper back to it’s roots.
00:50 Zoom in!
00:55 In ancient times, that is before the paper was invented,..
01:00 ..people used to carry information not only in their brains…
01:05 But on them too!
01:08 Writing was usually done on bones, bamboo tablets or animal skin.
01:17 Which made accessing these writings, err…messy and tedious.
01:24 There was however, one Chinese man, in the Han Dynasty, in 105 AD..
01:31 ..who revolutionized the way people wrote and read, forever!
01:36 The legend says, that a man named Cai Lun, once saw a wasp, knitting it’s nest.
01:43 It was then that an idea struck him.
01:48 He took the bamboo fibers..
01:53 ..added them to water..
01:55 ..and pounded them with a wooden tool.
01:58 After the fibers were thoroughly interwoven,..
02:02 ..he poured the whole mixture on a flat woven cloth.
02:07 Letting the water drain out.
02:09 He let the wet mixture dry up in the sunlight.
02:13 And, Voila!
02:15 After a few hours, the world’s first paper was born.
02:24 Cai Lun, presented his paper making process to the Chinese Emperor.
02:29 And received praise for his ability.
02:32 From that time, paper has been in use everywhere.
02:37 And, is universally called the paper of Marquis Tshai.
02:44 It was easy to make, the writers were happy,..
02:49 ..and of course, it was light weight.
02:53 Do you know, although the Chinese kept the secret of paper making,..
02:57 ..discreet for a long time.
03:00 The secret eventually started spreading,..
03:04 ..after the defeat of the Chinese T’ang army in 751 AD.
03:11 By the end of the 12th Century,..
03:14 ..a major part of the world was using, Cai Lun’s method of manufacturing paper.
03:21 But as the popularity of this spectacular new invention grew,..
03:26 ..so did the demand!
03:29 A demand that the manual method of paper manufacturing couldn’t certainly meet.
03:36 This eventually gave way to water-powered paper mills,..
03:41 ..the first evidence of which..
03:43 ..dates back to the Spanish Kingdom of Aragon in 1282
03:50 The most common fiber source the manufacturing process used..
03:55 ..was from the rag picker!
03:58 Which included hemp, linen, and cotton.
04:03 Use of this fiber source was to continue for another 6 centuries..
04:09 ..before another revolution!
04:15 Although this paper was cheaper than the traditional writing material..
04:19 ..such as animal skin and bones.
04:22 The cost was still high and production was low.
04:27 Keeping it out of the reach of a common man.
04:32 But this was only until two men, from different continents..
04:36 ..named Friedrich Gottlob Keller and Charles Fenerty..
04:41 ..tried wood fibre as a source material.
04:45 In light of this new discovery,..
04:47 ..the mills started replacing this new discovery to wood fiber.
04:52 And a new Era of papermaking began in mid 1844.
04:59 And by the end of the 19th Century, all the paper manufacturers in the West,..
05:05 ..were converting wood to paper.
05:09 And, my friends, what is paper without pen and pencils.
05:14 Awww… It would be the same as me without you.
05:20 So, with the invention of fountain pen and pencils,..
05:25 ..the paper industry skyrocketed!
05:30 Books were written and read.
05:33 Paper money was printed.
05:36 Even the gifts were wrapped in paper.
05:46 Sorry, sorry, sorry…
05:49 I said sorryyyy…
05:55 Don’t worry, we are safe now.
06:00 He was just a paper tiger.
06:03 So, what’s more?
06:05 Done… done… done. Oh, Yeah!
06:10 TRIVIA TIME!
06:12 Did you know, for every ton of paper that gets recycled..
06:16 ..we save three cubic yards of landfill space..
06:21 7000 gallons of water.
06:24 And, 20 trees.
06:28 It also produces 73% less air pollution..
06:33 ..than making paper from new materials.
06:37 And, what’s more? The amount of energy saved from recycling..
06:41 ..can power an average home for 6 months!
06:47 Global Toilet paper demand, uses nearly 30,000 trees, every day!
06:54 That is, 10 Million trees a year.
06:58 Almost half of global wood harvest, becomes paper!
07:03 Think about just how many trees we could save, if we all went paperless!
07:10 So, there you have it.
07:12 Some of the interesting things that I know about paper, and you should too!
07:19 I hope the next time you read or write something, it’s worth the paper it’s written on.
07:26 And remember friends, to tune in for the next episode.
