64 Repurposed Inventions, As Shared By People On The Internet

Sometimes a new invention is so cool it sticks immediately, and we cannot even dare to think about our lives without them. Think like, a potato peeler or a taco-making machine. Glorious! However, other inventions began their careers with purposes completely different from the ways we use them now. And, if you’d be interested to learn more about these repurposed inventions, stick around and read what cool discoveries people shared on this awesome Reddit thread talking about just that. 

If you’re still wondering what the heck we are going on about here, we can give you a couple of examples of reinvented inventions. So, spoiler alert, and here we go. Have you heard about Play-Doh? While we all know it as this colorful stuff for kids and adults to play with, it was originally created as a wallpaper cleaner. That’s right! Speaking of wallpapers – did you know that bubble wrap was intended to be a textured wallpaper? Sounds pretty weird, huh? Then we have things like Kleenex, Coca-Cola, a bazillion medicines, and plenty more cool inventions that were intended to be used in a whole different way, yet failed at that but found their glory in a completely unexpected place. 

So, ready to learn more about these famous repurposed inventions? If so, you know what to do; no need to invent anything new! Once you are done reading, please give your favorite submissions a vote (thanks again, people on AskReddit!), and share this article with your friends. Oh, and if you know of other famous inventions that were intended for an entirely different purpose, share your knowledge in the comments section!

“Paintball guns; they were originally called paintball markers and were invented as a way for loggers and park rangers to mark trees for trimming, cutting down, etc. without having to walk up to each tree with spray paint or something. A couple of dudes who were using them started shooting at each other for fun and paintball as a sport was born. In fact some people still call them ‘markers’ to avoid the stigma some associate with the word ‘gun’.”

“The Meyers-Briggs test. It was originally invented by a mother-daughter team who had no experience in either psychology or the so-called “hard sciences.” And while it did build somewhat on Carl Jung’s personality archetypes, even he had said that humans are far too complex to be categorized neatly like that. The test was never meant to be taken as seriously as it is. It doesn’t tell you who you really are, what kind of work you’re good at or that you can do, how or if you’ll fit into a company culture, who you’re compatible with, what you need from a relationship, or anything useful. It’s not scientific (even if it claims to be), and you can take the same test more than once and get different results.

Now we have people using them to make hiring and admissions decisions. Using them to make decisions about whom to date. Introducing themselves with it.”

In 1949 they had to stop calling it iron brew, because of restrictions from the government on what could be marketed as having vitamins or minerals, and it became the legally distinct irn bru.”

“Uber. It was supposed to be an app where you could hitch a ride with someone going the same place or in the same direction as you, with an option to pay for their time/inconvenience. This was a great idea since hitching a ride rather than ordering a taxi is better for the environment and would be cheaper as the driver presumably was going in that direction either way. Then it became a cheap taxi company whith low standards and insurance problems. In addition drivers “working for uber” will now drive around picking up people to make money, destroying any chance of environmental benefits.”

“Daily newspapers. Before TV and even before that radio became so widespread they used to be the fastest way of getting news and information to people. Nowadays, their emphasis is significantly more on serving as advertising tools, gossip columns, social commentary, etc. than reporting factual news without the extra serving of bullsh*t on top.”

Gorf_the_Magnificent replied:
“I’m old enough to remember a newspaper strike in the 1960’s. It was almost as crippling as a transit strike. No one knew:

what the local theaters were showing or when.

what TV shows were on at what times that night (there was no such thing as channel flipping in the pre-remote era, you planned out your viewing in advance; and since there was only one TV, you had to negotiate your viewing schedule with the rest of the family)

how the local sports teams were doing, compared to the rest of their division.

what sales were on at all the stores.

There’s more, but I can’t remember them all. Mostly, it was annoying not to have anything fresh to read when you came home from school or work.

The local TV news focused primarily on whether the newspaper strike would ever end.”
