00:00 The biggest accidental discovery I've made in my life was a 10-euro bill found in my old winter jacket.

00:07 Some people are more fortunate, however.

00:10 They discover underground cities dating back several centuries,

00:13 where they make inventions that turn them into millionaires.

00:16 Velcro was born from a simple walk in the forest.

00:20 Kellogg's corn flakes were inspired by a broken tooth,

00:24 and the Play-Doh paw saved a commercial empire from bankruptcy by pure chance.

00:29 In 1998, electrician John Williams made a strange discovery

00:34 that looked like an electric plug emerging from the ground.

00:37 While digging around, he noticed that it was embedded in a small rock.

00:42 This discovery took place in a rural area of North America,

00:45 far from any urban or industrial area, any airport, or any electrical installation.

00:51 This electronic part embedded in a solid block of granite

00:55 was named "Enigmalite" and was valued at $500,000.

01:00 Some scientists are skeptical of its authenticity,

01:03 considering it more like a cannula than an artifact left by extraterrestrial visitors,

01:08 as Williams claims.

01:10 However, the discoverer of this rock is determined to prove that it is indeed a technological relic,

01:15 perhaps even a real one.

01:18 If it is not a cannula, this small discovery could be a proof

01:22 that humans, or another civilization of the past,

01:25 were much more advanced than we had imagined.

01:28 They could have found a way to generate electricity long before humans in the 19th century.

01:34 Williams invited scientists to examine his discovery

01:37 without damaging the rock to determine its true nature,

01:40 but no one volunteered.

01:43 Williams consulted an engineer and a geologist,

01:46 who both confirmed that there was no trace of glue on the electronic component.

01:50 It was not welded either,

01:52 indicating that it is as old as the rock itself,

01:55 dating back to about 100,000 years, according to a geological analysis.

01:59 Dr. John Kellogg had a philosophy based on a biological way of life,

02:04 including regular exercise, massages, a lot of water,

02:08 abandonment of bad habits, little caffeine, and no meat at all.

02:13 At the end of the 19th century, he took over the management of a health institute in Michigan.

02:18 He one day made a mixture of flour, oats, and cornstarch.

02:23 Convinced that cooking whole grains at high temperature would make them more digestible and healthier,

02:28 he cooked the mixture twice.

02:30 Initially, he made biscuits out of it, but a patient broke his teeth on it.

02:35 Then, he decided to break them into small pieces.

02:39 It is difficult to determine exactly how Kellogg's cornflakes were born,

02:44 because there are many versions of the story.

02:47 Kellogg's wife, Ella, and her brother, Will,

02:51 claim to have played a role in the creation of the famous flakes,

02:55 just like several other family members and staff of the establishment.

02:59 The legend of the company would say that one day in 1888,

03:03 wheat-based cereal dough was left aside for too long,

03:07 fermenting during the process.

03:09 When it was finely spread, the slightly moldy dough turned into these perfect,

03:14 large and thin flakes, which became crispy and delicious in the oven.

03:19 Over the years, Will Kellogg continued to modify the recipe,

03:23 and realized that corn, and not wheat,

03:26 produced even more crispy and tasty flakes.

03:29 His brand, Kellogg's Cornflakes, became a company worth several billion dollars.

03:35 One day, the Swiss engineer, George de Mestral, went for a walk with his dog,

03:40 and came back with a concept that would later prove to be revolutionary.

03:43 On his way back from the forest, de Mestral noticed that his pants and the fur of his dog

03:48 were covered with small dots of xanthium.

03:51 He examined the beards under a microscope,

03:54 and noticed that they resembled tiny hooks

03:57 that were attached to the loops of the clothes and the fur.

04:00 Determined to reproduce this natural technology,

04:03 he began to design an extremely solid attachment system,

04:07 with multiple practical applications.

04:09 After several years of research and experimentation with different materials,

04:13 he finally opted for nylon.

04:16 In addition, he had to develop a special weaving profession

04:19 capable of weaving fibers in the right sizes, shapes and densities.

04:24 After 14 years of hard work,

04:26 de Mestral finally presented the world with the Velcro,

04:29 derived from the words "velour" and "crochet".

04:32 Although he hoped that his invention would replace lightning fastener,

04:36 the fashion industry initially perceived it as low-end and unattractive.

04:41 However, NASA recognized its potential

04:43 and began to use it in space suits and astronauts' helmets in the 1960s.

04:49 Today, the Velcro is omnipresent,

04:52 with a multitude of applications,

04:54 from shoes to toys, through the cushions of airplane seats.

04:58 Until the middle of the 20th century,

05:00 coal heating was the norm in most homes,

05:04 leaving the sewage that was encrusted everywhere in the house,

05:07 especially on wallpaper.

05:09 Cutol Products was the main supplier of cleaners for wallpaper at the time.

05:14 However, in the 1950s,

05:17 more and more people adopted gas, oil and electricity as heating sources,

05:23 which largely solved the problem of all this sewage.

05:26 The owner of Cutol Products desperately tried to save his company.

05:31 Meanwhile, his beautiful sister, who was a kindergarten teacher,

05:35 read that a cleaner for wallpaper could be used to make decorations.

05:40 Traditional modeling clay was too difficult to handle for her students.

05:44 That's how she decided to experiment with this material.

05:48 And it worked very well.

05:51 She shared her discovery with her loved ones

05:53 and proposed a name for this new product.

05:56 Play Dove.

05:57 With Cutol on the verge of bankruptcy,

06:00 it was the perfect opportunity for a conversion.

06:03 Quickly, large stores like Macy's and Marshall Field

06:06 showed interest in this new toy and began to distribute it.

06:10 At first, Play Dove only existed in white,

06:13 but it was quickly declined to red, blue and yellow.

06:18 They made several modifications to the original recipe,

06:21 but the basic composition remains largely the same as that used to clean the wallpaper.

06:26 An urban legend says that if you take all the clay to model Play Dove never produced

06:30 and make it pass through their machine,

06:32 you will get a snake long enough to wrap the planet 300 times.

06:37 A Turk was renovating his house when he knocked down a block of his cellar by force.

06:42 To his great surprise, he discovered a hidden tunnel behind the wall

06:46 that led to an old underground city.

06:48 This tunnel led to other passages, rooms and rooms.

06:53 It turned out to be an entire 18-story underground complex,

06:57 devoid of inhabitants and abandoned for a long time.

07:00 It was the city of Derinkuyu,

07:02 designed thousands of years ago to accommodate up to 20,000 people.

07:07 Anyone who built it has shown great mastery,

07:09 because digging tunnels in this soft rock presents considerable risk of collapse.

07:15 None of the floors of Derinkuyu ever collapsed.

07:18 The city was equipped with a sophisticated ventilation system,

07:21 including more than 15,000 ventilation shafts.

07:24 The upper levels benefited from better ventilation

07:27 and were reserved for bedrooms and living spaces.

07:31 The lower levels were mainly used for storage,

07:34 but also contained manholes.

07:37 Between the two were spaces dedicated to cattle, a school, a convent and small churches.

07:43 John Martin, a professor of silviculture,

07:46 was walking one night in a Wisconsin forest.

07:49 He used a UV flashlight to spot lichens,

07:53 mushrooms, plants and frogs that shone under this light.

07:58 Suddenly, he heard a flying squirrel cooing near a bird feeder.

08:03 He turned his flashlight on the animal and saw it tinted in pink.

08:08 The professor discussed this with his colleague,

08:10 and they decided to go deeper into their research.

08:13 They examined the skins of flying squirrels kept in museums

08:16 to determine if this pink glow was a common phenomenon.

08:20 It turned out that almost all the flying squirrel specimens they examined

08:23 showed this fluorescence.

08:26 However, ordinary squirrels showed none.

08:30 Other fluorescent animals, such as macaws and chameleons,

08:34 emit a blue glow under the UV light.

08:37 The only other mammals with a fluorescent fur

08:40 are about twenty species of opossum.

08:43 They inhabit various ecosystems and have different diets.

08:47 The only thing they have in common with flying squirrels is that they are nocturnal,

08:51 while other squirrels prefer daylight.

08:55 It is possible that pink glow is a function

08:58 linked to the perception and night-time spotting of flying squirrels,

09:02 especially in cold and snowy environments where UV light is more abundant.

09:07 Another hypothesis is that it could be used to attract potential partners

09:11 in the form of a fluorescent animal.

09:14 It is also possible that it is a form of mimicry.
