Soon after the shuttle bus stopped at the gate of Peking University, students from other universities and teachers from other universities also arrived one after another, and under the guidance of Peking University professors, everyone followed into the venue of Peking University to prepare for the competition.

The professors who came this time were not only professors who usually teach, but also several of them were veteran professors from scientific research institutions.

This competition is just to exercise their hands-on ability and increase their interest in the subject of physics.

After all, although these children are smart, they have only been exposed to physics for a while, and they don't plan to expect them to make anything special.

Therefore, other professors in the physics department and other professors only came to encourage everyone, and did not have much hope for the students' inventions.

After seeing the professors coming, all the students were a little excited on their faces, and their expressions were slightly nervous.

This is the first time that the students have turned the things in the books into reality, and everyone is a little apprehensive, everyone is not worried that they will lose the game, a few people only care about winning or losing, and most people are just worried that what they do is not good enough to disappoint the professors who bring them.

Director Gao handed over the invention number of Xiao Yao's class to the professor group of the organizer, Peking University, and according to the number of first come, first served, the number of Xiao Yao and the four of them was ranked last.

Qian Wentao was a little depressed, feeling that when he went out before, Ji Fengnan shouldn't have gone to the toilet to bring bad luck to his team, but it was not the first display and the second display.

Wang Yutong persuaded: "He didn't mean to say that you are a feudal superstition, now we can take a look at the works of competitors first, and see what kind of works other geniuses will make." ”

Qian Wentao said depressedly: "I originally wanted to be the first to come out in the competition to beat everyone, but I didn't expect it to be the last to play, forget it, and watch other people's works with peace of mind." ”

"Blame me, blame me, okay, let's see what other people do." Ji Fengnan scratched his head embarrassedly

Professor Chen walked up to a few people and smiled at them, obviously encouraging them to have good works without fear of being late, and then walked up to the stage and sat down with the other professors.

Xiao Yao looked at the three of them, and felt that they were really funny, although they looked a little unreliable, once they felt that they would do something, everyone would work hard in one direction.

At this time, under the announcement of the teacher, the other groups have already begun to show.

The first group was a clockwork-driven four-wheeler, and everyone went around to look around, and found that the car could still run quite far after the clockwork, except for the tires, which were all made of wood.

A lot of spare parts need to be done by hand, and the fineness of the team is very high, which shows that the hands-on ability of this group is very strong, especially the team members are all female students, and everyone admires it.

The second group made something similar to a lift, Xiao Yao felt that this idea was quite good, in the case of this construction is not extensive, can think of this invention, the elevator is lifted under the action of the motor, that is, there will be a little mistake in the designated position halfway, but it has been unanimously praised by the professors.

"Good idea." The professors encouraged the group.

The group members were overjoyed, and they waved their fists vigorously as they walked off the stage holding their inventions.

When one of the groups brought their invention to the stage, Xiao Yao was stunned, at first glance it was actually a robot, and when he thought about it, he felt that it was impossible, and now technology can't keep up with the ability to invent robots independently.

The robot on display is not a real robot as Xiao Yao guessed, it is almost a humanoid toy, and it does not have any language and listening to instructions.

The robot is controlled by electricity, and as long as the switch is turned on, it can walk a few steps. Xiao Yao took a look at it and knew the principle, that is, let the motor drive the gears, and the gears connect the joints to let the robot walk.

Xiao Yao praised them in his heart, no matter what people do, at least they already have the concept of being a robot in their hearts.

The other groups looked at the inventions of the first three groups and felt a lot of pressure, but they still wanted to show their inventions to everyone, although their inventions were not too innovative, but the professors still gave affirmation and encouragement.

Finally arrived at the strongest group in Xiao Yao's class, the five groups led by Lin Siyue and Xu Wenxin, because they were called the strongest group by them because of their third to seventh grades, when their invention was taken out, all the people in Xiao Yao's class gathered around and looked at it.

When a small boat was placed in the pool displayed at the venue, when Lin Siyue turned on the power, they immediately heard the sound of the motor clattering, and the boat operated automatically under the remote control in Xu Wenxin's hand, and it could turn around in the water.

They also built a small generator in the cabin to continuously generate electricity for the boat while the boat was moving forward.

The professors became interested at once, and after everyone came to the front and watched carefully, seven or eight professors picked up the boat and began to study.

I wondered if this ship could be used in reality if it was expanded to look like a cargo ship.

Xiao Yao secretly sighed, lamenting that his classmates were really demonic beings, and the idea of adding a generator in the middle of the journey alone defeated his own invention.

This group of people had never been exposed to physics before, and after studying physics for a semester, they could think of anything.

Now they don't have as much insight as the later students, they all thought of it themselves, and they did it with their own hands, which is really amazing.

Finally it was Xiao Yao's turn to be in their group, and Director Gao asked with a smile, "Xiao Yao, what is your group doing?" ”

I just felt very happy to be praised by all the professors, after all, Lin Siyue's group was also his student.

Qian Wentao replied confidently: "It's an airplane." ”

Ji Fengnan drove the cardboard box and took out the half-couple plane.

Looking at the aluminum panel of the plane shining silver, there is also a big five-pointed star drawn by Ji Fengnan with a red pen, which looks a little like a real plane.

Xiao Yao's classmates in his own class knew that these four people really didn't brag at that time, and what they did was really an airplane, but they didn't know if they could fly.

Gao Dao frowned and said, "This plane...... Is it a model or? "Gao Dao is a little unsure of Xiao Yao's invention.

Wang Yutong said firmly: "It can fly." ”

The professor and a group of students at the venue showed incredulity on their faces, this plane looks quite heavy, isn't it how to fly a paper airplane, throw it down from the upper floor?

Qian Wentao looked at everyone's disbelief and said loudly: "It can really fly." ”

This is chapter 239, and the chapter was wronged
