Ten bizarre inventions from the past that never caught on

People once caged babies several stories above the street


Published on March 1, 2026


Ever wonder what happened to all those "revolutionary" gadgets that promised to change our lives? Some ideas were just too weird, too early, or too wonderfully impractical to survive. Let's take a nostalgic trip through the patent office's hall of shame.

1

The baby cage (1930s)

Back when fresh air was considered a cure-all, London parents who lived in apartments faced a dilemma: how to give their babies outdoor time without a yard? The solution was a wire cage that hung outside the window, suspending Junior several stories above the street. Parents would just pop the baby in the cage and go about their day.

Shockingly, this didn't catch on. Perhaps it was the image of infants dangling precariously over busy sidewalks.

The isolator helmet (1925)

Imagine a giant goldfish bowl on your head, lined with cork, with only a thin slit to see through. That was the Isolator, designed to help people concentrate by blocking out all distractions. The inventor, Hugo Gernsback, thought sensory deprivation was the key to productivity. An attached oxygen tank let you breathe while you worked.

The problem? Looking like a deep-sea diver at your desk isn't exactly conducive to office camaraderie. Plus, trying to type while essentially wearing a fish tank proved impractical.

Motorized ice cream cone (1990s)

This battery-powered cone featured a small motor that rotated the ice cream for you, so you could just stick out your tongue and let technology do the rest. It was supposed to prevent drips and ensure even licking coverage.

The invention raised an important question: had we become so lazy that rotating our wrist was now an insurmountable challenge? Apparently, the answer was no. The motorized cone disappeared faster than ice cream on a summer day.

The Cyclomer (1930s)

This amphibious bicycle promised to let you pedal across lakes and rivers just as easily as riding down Main Street. It featured a boat-like hull and paddle wheels instead of regular tires. The inventor envisioned commuters cycling across waterways, avoiding bridge traffic entirely.

Unfortunately, the Cyclomer was heavy, slow on both land and water, and required the leg strength of an Olympic athlete to move at anything faster than a crawl.

5

Rejuvenation by goat gland transplants (1920s)

Dr. John Brinkley convinced thousands of men that transplanting goat testicles into humans would restore youth and vigor. For the bargain price of $750 (about $12,000 today), you could have surgery in his Kansas clinic and supposedly regain the vitality of your younger days.

Unsurprisingly, the procedure didn't work—goat glands don't function in human bodies. Brinkley eventually lost his medical license, but not before making millions.

6

The pedestrian catcher (1920s)

Image: Susan Gold

When cars first became common, someone invented a net-like contraption that attached to the front bumper to scoop up pedestrians before running them over. The idea was that the person would land safely in the net instead of under the wheels. It looked like an industrial-sized butterfly net.

The fatal flaw? Getting hit by a car and caught in a net is still getting hit by a car. Plus, the contraption made vehicles longer and harder to maneuver, probably causing more accidents than it prevented.

7

The piano for bedridden patients (1935)

Image: Beth Jnr

Picture this: you're stuck in bed recovering from illness, and what you really need is a full-size piano suspended over your body. That's what one inventor thought, anyway. The piano hung horizontally above the patient, who could supposedly play while lying flat on their back.

Beyond the obvious safety concerns of dangling a heavy musical instrument over sick people, there was the question of who actually wants to play piano while confined to bed.

8

Dimple-making machine (1936)

In an era when dimples were considered irresistibly charming, someone invented a face-shaping device that promised to create them artificially. The contraption used springs and knobs to press into your cheeks for 15 minutes daily until dimples supposedly formed permanently.

It didn't work, of course—dimples are genetic, caused by variations in facial muscle structure. But that didn't stop people from trying.

9

The Hubbard Electrometer (1960s)

L. Ron Hubbard claimed this modified lie detector could measure the electrical characteristics of your thoughts and help achieve spiritual enlightenment. Users held two tin cans connected to a meter while being asked questions. A needle supposedly revealed deep psychological truths.

Scientifically, it was just a simple ohmmeter measuring skin resistance—the same principle behind mood rings. But it cost considerably more and came with significantly more baggage.

10

The radio hat (1949)

Image: Nirmal Chaudhari

Why carry a portable radio when you could wear one on your head? This invention looked like a regular pint-sized baseball cap but contained a tiny AM radio with an antenna poking out the top. Earphones ran down to your ears, letting you listen to broadcasts while keeping your hands free.

The problem was that you looked absolutely ridiculous, like an alien trying to blend in at a baseball game. The reception was terrible, the batteries died quickly, and the whole contraption was uncomfortable.


Decoding

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

Treasured guest

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Code Adam

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

Code Blue

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Dr. Firestone

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

Code 10

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

Code Bravo

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

7

Code Alpha

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

10-33

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Signal 70

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Echo, Echo, Echo

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
