The first thing I want to invent is a new pen. I am a person who likes to use pens, but sometimes in the process of using fountain pens, I often accidentally spill fountain pens on my clothes and hands, which makes it difficult to clean them, which makes me very helpless. The new pen I want to invent not only looks beautiful, but also each pen is unique and can be made according to my favorite model. It can not only write beautiful words, but also find strange words by pressing shortcut keys, and it can also record and play music. If there are difficult questions to remember in class, you can record them and listen to them several times. You can also listen to Beethoven's piano music during recess. When writing, it can automatically absorb carbon dioxide harmful to human body in the air, and make carbon dioxide replace pen water, so that you don't have to worry about splashing on clothes or hands, and you don't have to waste time, and it is also helpful to human health. If everyone uses such a pen, it is equivalent to eliminating a major factor harmful to the human body-carbon dioxide.
The second invention is a clothes cleaner. Fashion makes many families' clothes pile up like mountains. The other two major problems caused by this excessive consumption are the energy consumed by washing clothes and washing clothes. We live in a cultural atmosphere of "wear once, wash once". In fact, in Britain, only about 7.5% of clothes can be called washing, and most of the rest just need to be thrown into the washing machine for a turn. If there is a washing machine in the process of replacing the washing machine, it will reduce people's labor and reduce the waste of water resources and detergent.
If I were an inventor, I would devote my whole life to invention, and let mankind live a very happy life.
