00:00So, let's start.
00:01Number 10, the Radium Girls' glow-in-the-dark paint.
00:05Back in the early 1900s, glowing paint was the height of cool.
00:09Factories produced radium-based luminous paint for watches, clocks, and even toys.
00:15The workers behind it all, mostly young women, later nicknamed the Radium Girls.
00:20The bosses told them to shape their fine brushes with their lips, dipping them repeatedly into
00:25radioactive paint.
00:26They were reassured that radium was safe, some advertisements even called it a health
00:31booster, claiming it gave you energy and vitality.
00:34Spoiler, it didn't.
00:36The women soon began to notice horrifying symptoms.
00:39Their teeth started falling out, their bones weakened to the point of snapping spontaneously.
00:44Some developed jaw necrosis, literally called radium jaw, where their jaws crumbled away like
00:49chalk.
00:50Doctors at first dismissed these effects as syphilis or hysteria, but eventually the connection
00:55became undeniable.
00:57The paint they were licking like cake frosting was slowly killing them.
01:01The scandal erupted into lawsuits, one of the earliest workplace safety battles in the
01:06US.
01:06The women who sued the companies were often already dying by the time their cases made it
01:11to court.
01:12The companies fought hard, but the truth won out.
01:15Their tragedy forced safety regulations in industries handling radioactive materials.
01:21So, yeah, a glowing wristwatch was trendy in 1920, but the cost was literal glowing bones.
01:28The invention was a lethal fashion accessory that left behind a radioactive legacy.
01:33Number 9, the baby cage of the 1930s.
01:37Picture this, you live in a cramped city apartment, maybe on the sixth floor, and you've got a
01:42baby.
01:43Playgrounds?
01:44Too far.
01:45Parks?
01:46Too crowded.
01:47What's the solution?
01:48According to some 1930s inventors, you strap your kid into a wire cage and hang them out
01:54the window like a potted plant.
01:56And yes, people actually bought these things.
01:58The baby cage was marketed as a way to give infants fresh air and sunshine.
02:02In urban areas, the cage was essentially a small wire box that you bolted to your window
02:07frame.
02:08You'd then stick your baby inside and let them dangle several stories above the street, directly
02:12above honking cars and clouds of exhaust.
02:15Newspaper clippings show mothers casually sipping tea while their kids hung outside like dangling
02:21laundry.
02:21Safety-wise, it was a nightmare.
02:23Sure, the cages were made of sturdy metal, but bolts and screws fail.
02:28And let's be honest, even if it held, the optics were horrifying.
02:32Imagine looking up from the sidewalk and seeing a baby suspended over your head in a bird cage.
02:38Eventually, common sense and building safety laws kill the baby cage trend.
02:43It's proof that desperation and bad design can create one of the most reckless parenting
02:48tools in history.
02:49Number 8, the iron lung car heater.
02:52In the early days of motoring, heating your car was a luxury.
02:56Before modern heating systems, winners meant you froze behind the wheel, wearing layers
03:00like you were trekking the Arctic.
03:02Then came a brilliant idea.
03:04What if you used the car's own exhaust to warm the inside?
03:07Yes, inventors decided to pipe literal engine fumes into the passenger cabin.
03:11This contraption, sometimes nicknamed the iron lung heater, worked by channeling exhaust
03:16gases through a heating system that vented into the car.
03:19At first it seemed cozy, drivers no longer had to scrape frost off their own breath while
03:25steering.
03:25But there was a problem.
03:26Exhaust contains carbon monoxide, a colorless, odorless gas that can kill you in minutes.
03:33The result?
03:33People would start their drive feeling toasty, only to nod off permanently before reaching
03:39their destination.
03:40In fact, a significant number of unexplained roadside deaths during the 1920s and 30s are
03:45now thought to have been caused by these heaters.
03:48Basically, they turned your Model T into a mobile gas chamber.
03:51The invention was eventually abandoned, but not before plenty of people fell victim.
03:56Nowadays, we complain about weak car heaters taking forever to warm up.
04:00At least they don't quietly assassinate us during the commute.
04:03Number 7, the miasma mask.
04:06Before modern germ theory, people believed miasma, or bad air, caused disease.
04:12The solution?
04:13Weird contraptions designed to filter or neutralize foul smells.
04:17Some inventors took this belief to extreme levels, creating bizarre masks filled with herbs,
04:22perfumes, or chemicals to cleanse the air.
04:25In practice, these things often did the opposite.
04:28Some designs funneled air through sponges soaked in vinegar, others had metal contraptions with
04:33burning incense chambers.
04:35The idea was that pleasant-smelling air would cancel out sickness.
04:40The reality.
04:41Breathing through damp sponges or chemical-soaked cloths made people dizzy, nauseous, and sometimes
04:47poisoned.
04:48Imagine trying to cure plague exposure by strapping a glorified potpourri bomb to your face.
04:53The most famous version, of course, was the plague doctor mask, the long bird beak stuffed
04:59with herbs.
05:00While creepy enough to star in a horror movie, it didn't actually stop disease.
05:04Worse, some designs trapped heat and reduced airflow, suffocating the wearer faster than
05:09the bad air ever could.
05:11Eventually, germ theory replaced miasma theory, and these gadgets went extinct.
05:15But for centuries, people sincerely thought perfume filters could outwit the Black Death.
05:20It's one of history's most dangerous examples of pseudoscience disguised as innovation.
05:25Number six.
05:26The safety coffin.
05:27One of the biggest fears in the 18th and 19th centuries was being buried alive.
05:32Medical science wasn't great at telling the difference between dead and deeply unconscious,
05:37so inventors decided to get creative, designing safety coffins.
05:42These were caskets rigged with bells, flags, or air tubes so the dead could signal if they
05:48woke up underground.
05:49Sounds clever, right?
05:50Except most of them didn't work.
05:52The strings tied to bells would jam or get tangled in the shifting earth.
05:57Some air tubes collapsed under the weight of soil, and in cases where the bell did ring,
06:01gravediggers often assumed it was wind, rodents, or pranksters.
06:06Even worse, some designs supposedly sped up suffocation by pulling fresh air out instead of pushing
06:12it in.
06:12There are a few accounts of safety coffins working, but far more of them failing spectacularly.
06:18Imagine clawing at the lid, desperately pulling a cord, only to realize the contraption was
06:24jammed shut.
06:25That's not a safety feature.
06:26That's an express ticket to a worse death.
06:29Today, premature burial isn't exactly a top concern, but safety coffins remain a darkly
06:35comic reminder of how fear and faulty engineering can collide.
06:40These weren't saving lives, they were adding a bell-ringing sideshow to an already grim situation.
06:46Number five, lead in everything.
06:48For centuries, lead was considered a miracle material.
06:52It was cheap, easy to mold, and showed up in everything from pipes to face powders.
06:57But, the real disaster came in the 20th century, when inventors decided to mix lead into gasoline,
07:03paint, makeup, plumbing, and even children's toys.
07:07The message was, lead is progress.
07:10The reality was, lead is poison.
07:12Inhaling or ingesting lead slowly wrecks your brain and nervous system.
07:17It damages memory, reduces impulse control, and lowers IQ.
07:21But for decades, no one cared.
07:23Lead gas gave cars better performance.
07:25Lead paint was vibrant and durable.
07:28Makeup companies even advertised the pure white glow of lead-based powders, never mentioning
07:33the small detail that it rotted your skin and teeth.
07:37By the mid-1900s, the effects were undeniable.
07:40Entire generations of children exposed to lead poisoning showed cognitive impairments.
07:45Cities with high lead use saw spikes in violence and neurological disorders.
07:50Scientists now believe lead exposure influenced everything from crime rates to public health crises.
07:57Even though most countries eventually banned it in consumer goods, the damage had been done.
08:02An invention that was hailed as a wonder material turned out to be one of the most catastrophic public health
08:08experiments in history.
08:09Number four, the trepanation drills of the 18th century.
08:14Trepanation, drilling a hole into someone's skull, is one of humanity's oldest medical practices.
08:20In the 18th century, inventors decided to make it more efficient by designing hand-cranked skull drills.
08:25The idea was that relieving pressure in the head could cure headaches, epilepsy, or mental illness, but in practice, it
08:33mostly just killed people.
08:34These drills looked like woodworking tools, except instead of boring into oak, they were boring into human brains.
08:41The process was slow, painful, and wildly dangerous.
08:45Without anesthesia, antiseptics, or an understanding of brain function, trepanation was essentially surgery with a carpenter's toolkit.
08:54Survival was rare, and even when patients lived, infections or brain damage often followed.
08:59Some surgeons swore by it, claiming miraculous recoveries, and in reality, those recoveries were probably just luck or placebo effects.
09:08Worse, charlatans picked up the practice, drilling holes in anyone willing to pay.
09:12What was supposed to be a medical breakthrough became a gruesome sideshow of human suffering.
09:17The hand-cranked skull drill stands as a terrifying reminder of how medicine once blurred the line between innovation and
09:25torture.
09:25Thankfully, modern neurosurgery doesn't resemble a carpentry project gone wrong.
09:30Number three, the jetpack that burned your legs.
09:33In the 1960s, the space age was booming, and inventors dreamed of putting jetpacks on everyone's backs.
09:40The concept, a personal flying machine powered by literal rocket engines.
09:45The reality, flaming exhaust blasting directly onto your legs with a side order of second-degree burns.
09:52The most famous version, the Bell rocket belt, could lift a person a few feet off the ground for about
09:5720 seconds.
09:58That's it.
09:5920 seconds less than the time it takes to microwave a Pop-Tart.
10:03It looked amazing in demonstrations, but pilots often ended up scorched, bruised, or in the hospital.
10:09The fuel tanks were tiny, the thrust was unstable, and landing wasn't so much a landing as a glorified faceplant.
10:16The US military tested them, Hollywood featured them, and engineers swore they'd be the transportation of the future,
10:24but the drawbacks were obvious.
10:26Too heavy, too hot, and way too dangerous.
10:28Testers described singed clothing, melted boots, and smashing into walls.
10:34Imagine strapping fireworks to your spine, and hoping the laws of physics take a coffee break.
10:39That's what flying a jetpack felt like.
10:42Jetpacks never took off, literally, but the dream lingers in pop culture.
10:48Every few years, someone announces a new, improved design.
10:52But, the same problems always return low fuel, high heat, and a serious chance of roasting yourself midair.
10:59The future everyone wanted turned out to be better left in comic books.
11:04Number 2.
11:05The Vibrating Belt Weight Loss Machine.
11:08In the 1950s and 60s, gyms and beauty salons had a strange fad.
11:13Machines that promised to shake the fat right off you.
11:16You'd step into a belt contraption, wrap it around your waist, and let it jiggle your midsection like jello in
11:22an earthquake.
11:23The pitch? Effortless weight loss, no sweat required.
11:27The belts vibrated with surprising force, leaving users red and sore.
11:31Instead of melting fat, they caused bruises, spinal strain, and in some cases, internal injuries.
11:36Yet, they became a cultural craze.
11:39Magazines promoted them, celebrities posed with them, and entire gyms filled with rows of people standing motionless while their bodies
11:47wobbled like human maracas.
11:49Of course, the science was nonsense.
11:51Fat doesn't just shake away.
11:53Real fitness requires exercise and diet.
11:57But, the machines sold well because they tapped into the eternal human dream.
12:03Results, without effort.
12:04People wanted to believe a belt could do all the work while they flipped through magazines.
12:09Eventually, the fad collapsed, but not before leaving countless customers with medical bills instead of smaller waistlines.
12:16Today, the vibrating belt is remembered as one of the clearest examples of how the fitness industry thrives on shortcuts
12:22that don't work, and sometimes actively hurt you.
12:26Basically, it was the flat tummy T of its era, just with more bruises.
12:30Number one, the blizzard of asbestos.
12:33For decades, asbestos was considered a wonder material.
12:36Fireproof, durable, and cheap.
12:39So, companies used it for everything.
12:41Insulation, clothing, floor tiles, and even children's toys.
12:45And then came the ultimate bad idea.
12:47Fake snow for movies and holiday decorations.
12:50The Wizard of Oz famously showered its actors in asbestos snow during filming, while Christmas ads encouraged families to sprinkle
12:58it around the tree.
12:59The problem, of course, is that asbestos fibers lodge in the lungs and cause deadly diseases like mesothelioma.
13:05Actors breathed it in on set, kids tossed handfuls of it during the holidays, and factory workers handled it with
13:11zero protection.
13:13Imagine decking the halls with poison flakes that were basically mid-century holiday cheer.
13:18The fake snow was especially tragic.
13:21Families would scatter it in living rooms, kids would make snow angels in it, and no one had any idea
13:26they were inhaling a carcinogen that would slowly kill them decades later.
13:30It wasn't just unsafe, it turned holiday magic into a health time bomb.
13:35By the time the dangers became undeniable, the damage was already done.
13:38Asbestos is now banned in many places, but traces still linger in old buildings, attics, and film reels.
13:45Looking back, it's surreal.
13:48Something marketed as cozy family fun became one of the most catastrophic health hazards ever packaged for home use.
13:56Merry Christmas, here's lung disease in a box.
