Teenagers have a lot of new ideas. Let’s have a look at these teenage inventions that might change the world.
Banana leaves usually go bad in two or three days. Tenth Hadith, a teenager from India, used UV to make the leaves stay fresh for a year. Tenth thinks that one day the leaves will be used for making plates, cups and other things.
David Cohen, an American teenager, built an earthworm（蚯蚓） robot. It is able to go into the smallest places, where humans or dogs can’t go. It will be used for finding people in a fire or an earthquake.
Remya Jose, a 14-year-old girl from India, found it tiring and boring to hand wash clothes in the nearby river. She reused some bicycle parts and created a washing machine that saves time, energy and keeps people fit at the same time.
Kenneth Shinozuku, a 15-year-old boy from New York, noticed that his grandfather who got Alzheimer’s disease（老年痴呆）would often leave home and get lost. So he invented the wearable sensors（感应器）to help people find their family members like his grandfather.
