Everyone has a dream. Everyone's dreams are different. My dream is to be a scientist. Every time I see the news on TV-a scientist has invented a magical potion; So-and-so scientist succeeded in making a fuel-efficient car. Whenever I see this kind of news, I am always excited, and I always hope to make contributions to people like them one day.

I remember one day last year, several partners and I completed an experiment-making a wind-driven car. We first went to the nearby scrap metal recycling station and bought an iron box without a cover, two iron shafts and six small buttons. Then we fasten the small button at the bottom of the box and put the shaft in. We removed the steering wheel and pedals from a useless tractor and loaded all these things into the car. Then, remove the useless blades of the electric fan, install them on the front of the car, and then connect them with the pedals. After all this, we bought four bicycle tires from the bicycle repair shop, installed them on the axle of the car, and finally fixed them. A car using wind power is finished. When we made this pneumatic car, we were very dissatisfied inside. Everyone proposes to sit on what they have created. When the pedal is depressed, the fan blades rotate. Oh, he runs so slowly!

In my childhood, I did more than one experiment, and there were many more. Now, they are all in the grocery store downstairs!
