Top 10 Terrible, Really Bad Inventions


They say that necessity is the Mother of invention but some inventions weren’t really all that necessary. And even worse, some inventions should never have been imagined, much less mass-produced and then thrust upon an unsuspecting world. Some of these inventions you know and some, thankfully, you are remain blissfully ignorant of. Well, sorry to burst your safe bubble, but here are the top 10 terrible inventions.

10. In-Vehicle Rear-Flushing Spittoon

Inventor: Dan L. Fain (U.S.)

Practical as this may sound, not as many people chew tobacco or spit snot out of their car windows as you may guess. Fain’s imaginative idea of hooking up a spittoon to the windshield washer fluid motor may have sounded like an award-winner to the Copenhagen Man, but to just about everyone else in the United States it made little, if any, sense. How often does the average human being have to spit out of his or her vehicle? Granted, there are obvious exceptions to this rule, but there are also so few exceptions that this invention never really, how should we say it… took off.

Unfortunately for Mr. Fain, the price tag on his invention was just a little too high for its inherent value. Yes, even for the Copenhagen Man. We advise that you simply roll down the window or open the door at a light. Or, if you’re an avid chewer or dipper, carry a Styrofoam cup. It’s easier than you think. Image:

9. “Small Sacrifices” Glider


Inventor: Otto Lilienthal (Germany)

Aptly nicknamed “the Glider King” by some of his peers and fans, inventor Otto Lilienthal if famous for developing and testing numerous gliders and other attempted flying devices. Lilienthal moved to Austria in his early years in order to try out his various glider designs on the Alps. After being interrupted by the Franco-Prussian War, in which he served voluntarily, Lilienthal returned to Austria where he started a business building steam engines and continued his pursuit for the dream of flight.

His last days were spent putting the finishing touches on what would prove to be his final glider design. After taking the plunge from a 17 meter manmade hill, Lilienthal experienced unexpected technical difficulties with his craft and plummeted into the soil. He broke his spine and died in Berlin the following day. Among his last words were, “small sacrifices must be made.”

The Wright Brothers are quoted as regarding Lilienthal’s findings as highly important to the developing field of aviation.

8. Bird Trap and Cat Feeder


Inventor: Leo O. Voelker (U.S.)


While pictures of this device are disturbing at best, the invention was registered with the U.S. Patent Office and was granted permission to be patented. The device is exactly what it says it is: a bird trap that catches birds and forces them into a thin cage, through which the family cat may claw and kill (and perhaps consume) the animal.

Interesting. Disturbing. Never produced in mass quantities. Image:

7. Razr Phone

Inventor: Motorola (U.S.)

Despite it’s name, Motorola’s Razr cell phone (also known as the MotoRazr) did not, well, shave. At all. Somehow, between the marketing, designing, and translation projects, somebody forgot to actually use the device. Following countless reports to the company about the Razr’s consistent failure to accomplish virtually any level of neatness, the company was forced to reevaluate the product’s status on the market. Following this failure, David Beckham’s heavily endorsed product, the Rong Zun 758 Mobile Razor has taken the place of the late, great Moto Razr and is having slightly better results.

Just shave at home, boys. It’s cheaper, cleaner, and won’t eat up your cell battery.

6. Motor Powered Roller Skates


Inventor: Unknown (China)

Made in China and brought into the U.S. via Amsterdam, these skates were sold mostly on street corners and over the Internet. They were not incredibly pricey, but they were incredibly dangerous. The skates had a handheld throttle device, and would reach 20mph in under 20 seconds. Although no proper brakes were affixed to the skates, an “emergency stop” button allowed for the user to lock the wheels, almost always resulting in a horrific 20mph accident.

It’s no mystery why these babies aren’t available at your local Toys ‘R Us.

5. Passenger Seat Fuel Tank


Inventor: Kenneth E. Brock (U.S.)

Mr. Brock, an attorney by trade, suspected that by creating a fuel tank in the shape of a passenger seat, an airplane could achieve greater flight distances. At first the invention seemed marvelous, but upon further research (allowing other people to hear his idea), he discovered that potential passengers of these “seat tank” planes were mortified that an entire canister of fuel could be in the seat in front, behind, or beneath them. With no shield to guard against explosion or leakage into the main compartment of the aircraft, the idea was eventually disbanded and left for others to pursue a more stable and logical means of increasing the range of civilian aircraft.

It appears that Brock, following the EAA’s lack of interest in endorsing the design, attempted to create a passenger seat fuel tank for use in sports cars and other vehicles. Not surprisingly, the potential passengers in these vehicles had the same response. “What happens if we get into an accident? Won’t the tank explode all over me?” Brock had little success in answering this question, and his 1971 Passenger Seat Fuel Tank mission fizzled out into a failed dream.

4. Smile Scanner


Inventor: Keihin Electric Express Railway (Japan)

Don’t be fooled by their cheery, personable faces: the Keihin Railway workers operating their stations may be far from happy. Their bared teeth and upwardly curving dimples are mandatory and cameras and computer software designed to detect and critique the “cheerfulness” of their smiles are monitoring them.

Many folks thought that the mechanization of the human race would stop with bionic arms and legs. It is plain to see that these people spoke too soon. These newly invented machines have now infiltrated our mood zones, arresting the human freedom to display an “improper” emotion.
This is wrong on so many levels.

3. TNT


Inventor: Joseph Wilbrand (Germany)

Originally intended for use as a yellow dye, Wilbrand created the first batch of trinitrotoluene (the explosive commonly known as TNT) in 1863. This seemingly innocent yellow dye sat on the table for roughly 40 years until the early 1900s, when laboratory scientists realized its efficiency as an explosive. Trinitrotoluene was researched, tested, and in action for WWI and WWII.

TNT is used for both constructive (leveling old buildings to create new ones) and deconstructive (war, terrorism) purposes. The reason for its inclusion in this list has to do with the unfortunate misconceptions of Mr. Wilbrand, who failed to realize that his yellow dye, while only mildly successful at coloring German flags, could have earned him a princely sum from the many militaries of the world who were, at the time, employing the usage of comparatively primitive explosives.

2. The “Best” Morning Sickness and Sleeping Pill (Thalidomide)


Inventor: Grunenthal Pharmaceutical Company (Germany)

Developed as a cure for “morning sickness” in 1944, Thalidomide was rumored to be the “best” cure for insomnia, coughing fits, and headaches. The drug has since been described by many as one of the worst medical blunders in the history of the world. After being prescribed to countless pregnant women in the late 1950s, severe birth defects resulted, affecting upwards of 20,000 newborn children.

Despite its propensity to causing horrific birth defects, Thalomide is still used on primates and other furry creatures, for which it carries no negative side effects. The drug, which has held many titles and boasted many capabilities, was originally developed as an antidote to Sarin gas.


1. Chlorofluorocarbons (CFCs)


Inventor: Thomas Midgley, Jr. (U.S.)

Thomas Midgley, originally a mechanical engineer, developed the gasoline additive tetra-ethyl lead. This advancement led to the immediate production of chlorofluorocarbons, the “anti-atmosphere” molecule that threatens to wipe oxygen off the face of the Earth. At the time, his discovery was readily applauded. However, now we know that the compounds released by gasoline engines designed to turn oxygen atoms into chlorofluorocarbons may very well lead to the total depletion of the ozone layer.

It has been said that Thomas Midgley, who holds dozens of patents to his name, has adversely impacted the atmosphere more than any single organism in the history of our planet.

  1. CFCs did not make refrigeration possible on a mass scale. They were not the only refrigerants around when they were invented. Many of the HCFC refrigerants that replaced them were invented around the same time. Ammonia refrigeration was invented even earlier and is still used for large commercial freezers. It is simply that the stuff was cheap and marketed and not adequately tested.

    Also, if the manufacturers had limited CFCs to refrigeration there would not have been as big a problem with the ozone layer since the freon in a refrigerator is in a closed circuit. It’s when they started using CFCs as spray can propellants that problems started since people started discharging tons of the stuff into the atmosphere. We didn’t really need freon – charged hair spray to progress technologically.

  2. Also, CFCs made a little thing called refrigeration and air-conditioning possible on a mass scale. Without it we’d have almost none of the modern conveniences we have today, including the computers that make this website (and all the others) possible.

  3. Chlorofluorocarbons do NOT destroy oxygen. They break down Ozone, a compound of Oxygen. Ozone is useless to humans for respiration, but they do filter UV rays. They are also partly responsible for smog.

    You eff’d up BIG on that description.

  4. As to number 5 on the list; Seat tanks are very common on ultralight and Light Sport aircraft. But this one should really be left on Snopes. Firstly, the concept of a seat tank works on a very small, single or dual aircraft as the size and placement of the tanks so close to the engine permit it. If you were to use these tanks on, say, a jet liner they would be self defeating. The cost associated both in weight and in expense of the plumbing to take the fuel from the seats to the engines would be prohibitive. Also, the EAA does not endorse products, I am a member so this I know. I think the author was meaning the Federal Aviation Administration. The FAA does allow seat tanks so at this point I think the author has fallen for an internet hoax of some sort and this list needs to be reviewed.

  5. “The compounds released by gasoline engines designed to turn oxygen atoms into chlorofluorocarbons may very well lead to the total depletion of the ozone layer”

    Hold on……what?

    Turn oxygen atoms into CFCs? You might want to rethink that sentence; it’s quite possibly the least scientifically accurate I’ve ever read.

  6. i can’t believe you missed the obvious.
    1. plastic- became popular in 1920s. before its invention, there was no garbage. everything got recycled by nature. today, even at the most remote forest or beach, you’d find plastic.
    2. mrt or subway trains- worst design of transport ever. leaving a big space for people to stand on instead of horizontal seats and wide doors.
    3. spraynets- how many hairs have been terrorized by this? and not to mention, its danger to ozone layer? thank goodness, than right now its dated, however, its terror will forever stay in 1980s family and media pictures.
    4. cars- yes! i know the whole world would disagree. but why metal? why should it be fast and heavy? why should it have to be fatal? how many millions of people die each year because of that moving metal box? compare ford’s invention in the 1890s.

  7. among all inventions, the bad invention is RAZR PHONE. but i also agreed to mr: Euin that atomic bomb is worest………………….

  8. Jojo Bizarro on

    Among the worst inventions in history, car alarms should rank very high. They just annoy your neighbors, and when your car does get stolen despite the thing wailing away, because you so learned to tune out all the false alarms that you didn’t realize this was the real thing, your neighbors all point and laugh at you and the empty parking spot where your car used to be.

  9. Worst invention in human history = the atomic bomb. Im amazed that it isnt on that list

    • Really? The only time it was used, it likely saved hundreds of thousands of lives, and while the tensions and fear are real, it has also prevented another global scale war on several occasions. Deplorable, isn’t it?

      • Yes it prevented another global war but it was also the cause of the Cold War which led to the Vietnam War and the Korean War, among other things.

  10. Worst inventions in our history…… Money…. Television…. Weapons…. and the Internet!!!
