Time magazine recently selected 50 worst inventions.

These inventions involve transportation, financial communication, electronic games, medical care and many other fields. Here, we have selected some inventions to introduce to you.

Kaloc cave shoes

No matter how many people are in pursuit, these casual shoes can't get rid of the "ugly" hat. Karochi hole shoes landed on the market in 2002, mainly rubber shoes, but also introduced high heels and lazy shoes. Kaloch announced on April 26th that the company will also launch ballet flats. Its CEO said: "If we can introduce more fashionable styles, we can attract more consumers to buy them." It seems that Carol is determined to carry this rotten shoe to the end.

Segway

Segway is an electric-driven, self-balancing personal transportation tool. When 200 1 went on the market, the inventor Dean Carmen hoped that it would bring a revolution to the world transportation mode. However, this kind of vehicle is now just a toy car for supermarket security guards and lazy tourists.

Pop-up advertisement

Since the introduction of pop-up advertisements in web browsers in the early 20th century, people have nowhere to hide. After the website adopted this trick, it undoubtedly benefited a lot, but the users were angered.

Automatic tuning software

This technology can make the voice of poor singers beautiful and moving, while the voice of poor singers can only sound like robots. Auto-tuning software makes singers such as kanye omari west and Cher mistakenly think that they are also experts in interpreting deep vocals. In this regard, we can only say: "Thank you very much, great computer."

Sunbed

Everyone knows that exposure to ultraviolet rays will have a negative impact on the body. In fact, about 90% of skin cancers are directly caused by ultraviolet radiation. Tanning bed is also an important factor to induce skin cancer. In the 1970s, sunbeds appeared in the American market. A study conducted in April of 20 10 found for the first time that using tanning beds indoors is more likely to make people dependent, and the way of addiction is the same as taking drugs or drinking alcohol.

Mobile phone finger sleeve

When playing iPhone, many people are really worried about leaving fingerprints on the display. Finally, an Austrian company found a solution to this problem: covering each finger with a mobile phone finger cover made of latex. Since the price of mobile phone finger covers is 10 euros, the company believes that there must be many consumers walking in the street wearing pink, white, blue or black finger covers. The company also produced a size chart to help consumers determine their finger sizes.

Smiling face scanning

In 2009, employees of Keihin Express Rail Company in Japan needed to scan smiling faces every morning. The company used a "smile scanning" software to analyze their facial expressions and score them. If this is not stupid enough, they must also carry their ideal smiling face pictures with them to remind themselves to stay in good condition all day.

Pay toilet

From June 5438 to October 2008, the first paid toilet in new york was opened to the public in Madison Square Park. For 25 cents, people can get 15 minutes of private time, which is equivalent to parking time. But what's really special is that the time limit of 15 minutes is up, there is no need for security check to get tickets, and the pay toilet will automatically open the toilet door and expose its guests. Airlines have become buyers of this kind of toilet, and they reset the business class toilet 15 minutes at a time.

junk e-mail

Anything free has a corresponding price, and one of the biggest problems related to e-mail is spam. Spam may seriously affect the life of ordinary computers.
