[2020·太原市高三模拟试题] Great inventors like Thomas Edison have influenced people's lives with their inventions. While their contributions are certainly valuable, other amazing inventions were actually created by children!
The trampoline
Trampolines are great for both fun and exercise, but they are a fairly recent invention. In the 1930s, George Nissen was inspired to make a bouncy “net” after seeing a circus performance. He thought it more entertaining for performers to continue bouncing instead of landing in a net. So, at the age of 16, he made it by stretching thick cloth in a metal frame.
The Popsicle
Cold weather led to the creation of a delicious invention — the Popsicle. Frank Epperson was just 11 years old when he accidentally created his first Popsicle. He was making himself a soda drink and left his glass outside overnight. When he found it in the morning, it had frozen solid with the stir (搅拌) stick still in the glass. And the first Popsicle was born.
Braille
Threeyearold Louis Braille experienced a serious eye injury that blinded him in both eyes. He struggled to read by moving his fingers across raised letters, but that proved very difficult. At the age of twelve, Louis learned about a communication system where messages could be read silently with fingertips. He changed it and created Braille. It's now used around the world!
BEACON
When Hannah Herbst was just 14 years old, she was named America's Top Young Scientist for inventing a device called BEACON. After receiving a letter from her Ethiopian pen pal, Hannah was inspired to create a device that could convert the energy from ocean waves into electricity which she hopes will help people without easy access to electricity.
