Why haven't scientists invented it yet?

There are a lot of things that scientists haven't invented yet or we don't use in everyday life. Are they all impossible or can we have them one day?

1. Flying cars

With all the cars on the road and the problems of traffic, why haven't flying cars become popular? One reason is because cars are very heavy so they are difficult to fly. There are other problems as well. Cities have roads for cars, but they don't have runways. And we have so many problems on our normal roads, do we really want the same problems in the sky?

2. Teleporting

Teleporting is moving objects and people from one place to another without transportation or walking. Teleporting is a very fast way to travel, but scientists haven't discovered how to do it. Solid objects are made of atoms and with teleporting you have to move each atom one by one. A human being is made of trillions of atoms, so it's very difficult and scientists don't have the answer at the moment.

3. Robot servants

Actually, scientists have invented robots, so why don't we all have them? Probably because the technology is very expensive and the robots often break down. But many companies in Japan have made prototype robots for houses. They wash clothes, switch on the TV, turn off the lights and change the music. Many scientists think we can all have a robot servant in our home in about ten years.

1. In a survey at Stroud High School near Gloucester, 75% of students said they “check social media constantly”, and more than half wanted to control their use of mobile phones. That's why four students organized a “digital detox” week, when 400 students, teachers and parents didn't use any mobile devices at home or at school. Jess Hourston, one of the organizers, said her schoolwork got better during the experiment. “It wasn't as hard as I expected,” she said. Hannah Cox agreed. She said it was better “to talk to your friends in real life!” Most participants felt less stressed and realized they had more free time while they weren't using mobile devices. The students' experience corresponds with a recent survey. It found that children who spend little time using social media are less likely to have symptoms of mental illnesses, including stress.

2. Stroud High School have now banned mobiles all day for 11- to 13-year-olds, and 14- to 16-year-olds can only use them at lunchtime. The ban hit headlines in the media, with many people saying it was too strict. But people now think that the school is leading the way in addressing problems caused by mobile phones, and many other schools in the UK are also introducing restrictions on mobile phone use.
