The flashlight was born.

Modern Wen Mingzhen should thank the American inventor Thomas Edison, who made the first white light with commercial value and brought light to mankind. However, Conrad Hubert deserves the same respect. He immigrated from Russia to the United States 0/00 years ago and invented the flashlight.

Hubert came home from work, and a friend proudly showed him a flashing flowerpot. It turned out that he put a battery and a small light bulb in the flowerpot. As soon as the switch was turned on, the light bulb lit up the flowers and looked dazzling.

Hubert was fascinated by it, which inspired him. He sometimes walks in the dark at night, one foot high and one foot low, which is very inconvenient. Not long ago, he had to carry a heavy oil lamp to the dark basement to find something. He thought, wouldn't it be practical and convenient if you could use electric lights to carry around? So Hubert put the battery and light bulb in a tube, and the first mobile lighting flashlight came out.
