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.
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.
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.
The pedestrian catcher (1920s)
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.
The piano for bedridden patients (1935)
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.
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.
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.
The radio hat (1949)
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.
