Come up with an invention.

"Rinrin Bell ..." At the beginning of the class, the teacher said, "In this class, let's talk about our own inventions and see whose whimsy is good." "Good good!" The students were crying with joy, all holding their hands high.

Tan Yifei was the first to speak: "I want to invent a satellite, and I can catch criminals by inputting their names and fingerprints!" " You can catch it even if you escape to the ends of the earth! "The students listened admiringly, and the teacher nodded.

Then, Ouyang Yangliang also expressed his opinion: "I want to invent a needle, and you can change the food you want to eat by pressing it." It is very convenient to carry and is a must for travel. " "oh! What a rich imagination! " The teacher gave a thumbs up.

I also stood up excitedly. "It is very inconvenient for people who don't have a house to travel now. I want to invent a compressed travel room, which can become bigger and smaller, and can also become various houses, which can live at sea or in the sky! "

The students talked a lot of fantastic ideas, and everyone listened to them very mysteriously, but can these fantastic ideas really be realized?

The teacher understood our doubts and said with a smile: "Nothing is difficult in the world, I am afraid that there is a will!" Imagination is like a door, if you open it, you will succeed!
