Guan Ziyan received the message from Broken Cocoon's mobile phone, so she carefully reviewed the video of the water ignition, which should really be the same as what Broken Cocoon said. The prop had a black base half a foot wide and three feet long, and from the outside it looked like a stable base for the prop.

There was a protrusion in the middle of the pedestal, blocking a section of the copper pipe, and Guan Ziyan now understood that the thin copper pipe entered the pedestal from that protrusion, and then circled a few times and then came out from there.

Basically, all the students in this kind of experimental school have been exposed to it in the experimental class, but they have not used it for magic, and the copper pipe is straight, so they can't light a match, and of course, they haven't thought about using this experiment for magic.

As for other magic tricks, Guan Ziyan also knew most of the principles, after all, her uncle Guan Cheng was a quasi-high-level magic magician, and she had learned a lot of knowledge in this area.

These college students are just magic enthusiasts, and they can't do anything too good. It's just that even this kind of small magic trick also makes other students who don't understand magic extremely enthusiastic.

When she heard that the host was announcing her name, Guan Ziyan's mood was still a little nervous. Her magic trick can't be regarded as prop magic, in her imagination, it must be too far behind the prop magic trick of the mirage that Zhang Mingming participated in the primary magic rehearsal competition.

She also didn't know what kind of reaction the modified chip and Xun Menglong's mixture would have, but thinking that the cocoon had allowed her to draw the main building of the school, she stubbornly thought that this magic trick should be very exciting.

Thinking of this, she took a deep breath and said to her classmates who came on stage with her: "Don't be nervous, we are the best." ”

The classmate smiled bitterly, thinking to herself, she has never tried this magic trick, in case she gets out of trouble on stage, haha, she doesn't understand where Guan Ziyan's confidence comes from, if it was Zhang Mingming who repaired this prop at that time, she would be much more confident.

This prop is not big, weighing about four or five pounds, strictly speaking, it is a high-level fireworks launch device, after powering on, use the chip to trigger the three tubes on the prop, each tube can spray different fireworks and finally combine into a gorgeous picture.

Guan Ziyan said some clichés on the stage, and then made a few small jokes with everyone, saying that he was not sure about his magic, and everyone should not laugh if he made a fool of himself, in short, he first laid a foundation for the magic he was about to perform.

As she spoke, her classmates had already plugged in the power and asked the gaffer to dim the lights on the stage, and everything was up to chance when she pressed the button at the back of the seat. Guan Ziyan didn't have any worries at this time, anyway, there was no turning back.

She pressed the button and stood up and stepped aside, only to hear a slight loud thud and a flame spewing out of a tube, but no smoke was produced.

Almost all fireworks will kick up some dust when they are spewed, and they will also have a strong smell of nitrate. The current fireworks are not very high, only two or three meters, unlike other fireworks that are more than ten or dozens of meters high, Guan Ziyan obviously heard the low laughter of the students of the magic club in the audience.

But this tube of flames just erupted, but it made people who really knew the goods feel different, and even the surprised look on the faces of the classmates who had just laughed had appeared on their faces.

The fireworks erupted, and a line of flames was dragged at the tail, which stood out under the not-so-bright bulbs.

Tonight, the wind was strong, and the leaves on the edge of the square rustled from time to time.

The flame that followed the tail was not blown away by the wind, but instead formed a rhythm in the wind, stretching up like a snake trying to leap into the sky, merging with the first fireworks.

I don't know what the reason is, what kind of chemical reaction seems to have occurred between the fireworks that came later and the fireworks that came out first, only to see the light disperse, and a red school logo appeared, and at the same time there was also the school motto of "seeking truth from facts, daring to be the first". Under the blowing of the wind, it is like the moon reflected in the water, gently undulating, but without a trace of dimming.

Guan Ziyan and the classmate who was an assistant couldn't hide their excitement when they saw this scene, clenching their fists tightly and staring at that strange phenomenon.

"No wonder the wind can't blow away, so he actually uses magnetic sand?" The middle-aged man in the audience was so shocked by this situation that he almost stood up, and pressed his hands on the armrests of the chair.

He is Fu Yuansheng, the president of the Magic Society, a pure senior magician, who does not know abilities or illusions, but has a very high attainment in psychological magic and technological magic.

However, he still doesn't know why the magnetic sand doesn't stick to each other, but doesn't attract each other like dust scattered in the air, and the logo is clearly a scene that can only be formed when a certain ingredient is burned. Before he could think about it, he saw fireworks erupt from another pipe.

This time, the fireworks are even more "huge", and it is said to be huge because this fireworks are thicker, and there are more light spots of various colors in the sparks, which are colorful and dazzling.

The fireworks made the logo a little higher, and then a set of images quickly appeared in the fireworks, as if someone was drawing a sketch in the air.

There seemed to be clouds and mist in the fireworks, and those points of light loomed inside. Some points of light burst out of the clouds and gathered together to quickly form the school gate, and then there were points of light from the clouds and fog one after another, converging into the auditorium, teaching building, library, square relief and other school landmark buildings.

The points of light flutter like fireflies, forming a beautiful picture, and when these buildings are connected, the general view of the school is presented to everyone. Seeing groups of familiar patterns, the college students in the audience stood up one by one and looked dizzy, so excited that they held their breath, for fear of scaring away the beautiful picture in front of them.

When the color of these images is about to fade, a third pipe erupts with fireworks, making the images that seem to be about to disappear red. The flame spewed out of the third pipe burst into the top of the LOGO, forming a few words: Happy Tianyuan University Student Day!

Then these images suddenly rose to more than ten meters, and a huge firework like a jellyfish exploded, covering the two-zhang square sky, which was extremely bright.

The architectural picture slowly loses color and slowly disappears, and only then is there a palpable exhalation sound from the audience, followed by a loud cheer.

Since seeing those pictures slowly disperse, as if blown away by the wind, Fu Yuansheng felt as if he had lost his soul. His mind was always full of the intertwined images he had just had.

Magnetic sand, nitrate, carbon powder, phosphorus, dyeing agent...... These ingredients flashed in his mind one by one, and formed a broken formula, and he didn't return to his soul for a long time, and he still had the magic of Guan Ziyan in his mind.

"Magnetic sand can compress those components in a certain space and cannot leave, nor can it be blown away by the wind, but why doesn't magnetic sand fall, it can't be lighter than air?"

"Why do the things that come out of fireworks interact with each other to form different chemical reactions, and why are there so many layers?"

"Even if there is chip control, why don't the three sprayed pictures repel each other? Each picture is a separate one, why doesn't the magnetic sand in them interfere with each other?"
