AMAZING NEW INVENTIONS
Every year, more and more amazing things are invented. Here are three of our favourites for this year.
A. Fukuda’s Automatic Door
Can you imagine a door that fits around your body as you walk through it? Fukuda’s Automatic Door was designed in Japan by an inventor named Rikiya Fukuda. It automatically indentifies movement and only opens just enough to match the shape of the person or object coming through. So, what are the advantages? It saves energy by helping to keep the same temperature in a room. It can also prevent dirt and other materials from being carried inside. As well as people, the Automatic Door works for small objects, like packages delivered to a post office, or for larger things, such as a car coming through a garage door.
=>c. It’s a device that knows when you are coming.
B. The Hand Roll Piano
Traveling musicians will be happy with this invention. The Hand Roll Piano was invented by the Japanese company Yamano Music. What makes it different is that it can be rolled up like a blanket. This makes it easier to carry and easier to store. The keyboard is 100 cm long but weighs just 1 kg. It has 61 very thin keys and is made of rubber. It’s convenient to carry, but it’s also a great instrument. The piano can be played for up to 15 hours on standard batteries. It has more than 100 sounds and its own speaker.
=> d. It makes entertaining easier.
C. The LifeStraw
Today, more than one billion people in the world do not have safe water. However, it’s been discovered that for the price of a cup of coffee, a life can be saved. The LifeStraw, which costs just $3, is a device for purifying water. It is able to turn dirty water into drinking water. The drinking straw was designed by the Swiss-based company Vestergaard Frandsen. It uses seven types of filter to make water clean enough to drink. It can prevent illnesses and it can also create safe drinking water for victims of hurricanes, earthquakes or other disasters.
=> a. It’s an invention that saves lives.

Noise is constant and loud sound. To measure the loudness, or volume of sounds, people use a unit called a decibel. When a sound is louder than 70 decibels, it can cause noise pollution. Do you know that the noise from a vacuum cleaner or a motorcycle can result in permanent hearing loss after eight hours? The sounds of a concert are even more serious. They can reach as high as 130 decibels and may cause immediate and permanent hearing loss. Noise pollution can also lead to headaches and high blood pressure. If you are listening to music through headphones, and other people can hear it. it means the music is too loud and unsafe. If there seems to be a ringing or buzzing in your ears, it means the noise is affecting you and damaging your hearing- Wearing earplugs when you go to concerts or other loud events, and listening to music through headphones or headsets at safe levels can help you reduce the effects of noise pollution.
