Wang Qi got dressed, washed briefly, went downstairs and checked out at the front desk, and took the deposit.

At this time, it was already past twelve o'clock at noon, and thinking that he might only be able to eat leftovers of soup when he went to the cafeteria at this time, he simply found a ramen restaurant nearby, and ate a bowl of Lanzhou ramen with coriander and red oil, spicy and fragrant, and ate it was a sweaty, tongue-in-cheek, and the white shirt on his body was completely attached to his body.

"Cool!" Wang Qi licked his lips, threw down the three oceans to pay, pulled a piece of soft paper from the carton and wiped his mouth, and got up to leave.

Before returning to school, he bought two packs of cigarettes at a cigarette stall on the side of the road, a pack of Yuxi, which was blackmailed by Liu Qing, and a pack of Longfeng Chengxiang, which he smoked himself. He learned to smoke after entering the university with a few smoking guns in the dormitory, but the smoking addiction is not big, dispensable, belongs to the category of smoking, buy a pack, if he just smokes alone, three a day in the morning, noon and evening, at least it can last for a week. But he is generous and informal, and every time he smokes, he will give his classmates a round to meet people, plus the guy next door Liu Qing who often asks him to smoke, so that he has to consume a pack almost every two days.

After buying cigarettes, Wang Qi went to a haberdashery store to buy a thermometer with a temperature range of -10 degrees Celsius and a ruler at a stationery store. Diagonally opposite the school gate, there was an old woman who set up a stall to shoot balloons with an air gun, and when he returned to school, he bought two balloons for a dime.

Cigarettes, thermometers, balloons that had not yet been inflated, along with his wallet, mobile phone, lighter and keychain, Wang Qi threw them all into the cube. What other magical powers does this cube have, Wang Qi doesn't know, so let's use it as a storage bag in Xianxia novels for the time being.

————————————

When Wang Qi returned to the dormitory, it was not surprising that he was interrogated by everyone in the dormitory:

"Xiao Qi, where did you run last night?"

"Did you go for wild food?"

"Surely! You see that he is dressed like King Wu Zheng, on a hot day, he puts on all his leather shoes, there is no weirdness and there is a ghost!"

"Xiao Qi, how deeply is your doll hidden? Tell me honestly, which beautiful woman was harmed by your baby? How many times did you become a groom last night?"

“……”

In the face of the ridicule and ridicule of his roommates, if it were yesterday, he would definitely deny it, and he would also feel discouraged and depressed because of Liu Miao's rejection.

But now, Wang Qi "holds the artifact in his hand and is self-explanatory", only smiled and winked at the people in the bedroom, and replied with a serious meaning: "You guess?"

After speaking, he ignored the roommates around him who were aroused by him and yelled at him to confess, took off his clothes and pants, turned around and walked into the bathroom.

Outside the bathroom, a couple of bored guys banged on the door and asked him to "confess leniently and resist strictly."

Of course, Wang Qi ignored this.

While taking a shower, he summoned the cube and began to use the three gadgets he had bought outside at noon to further study the properties of the cube.

First, he took out the thermometer and found that the thermometer was reading almost exactly the same temperature as when he had put it in not long ago, which was today's temperature, 38.2°C.

"Could it be that the temperature inside the cube is in sync with the actual temperature?"

In order to verify his idea, Wang Qi took out the lighter from the cube and used the flame to grill the thermometer's thermometer's temperature bubble, and saw that the red liquid column of the thermometer rose rapidly, quickly exceeding 80 degrees. He was worried that the thermometer would explode if he continued to roast it, so he threw the thermometer into the cube when he was in his eighties.

After that, Wang Qi began to measure the length of the sides of the cube with a ruler inside the cube. The ruler is for students and is only 20 centimeters long, which is much shorter than the border of a cube.

But this is not difficult for Wang Qi, last night he found that he can use his consciousness to move everything in the cube - up and down, left and right, rolling, rotating, and even making them do curvilinear movements, which is very magical.

Wang Qi used his consciousness to move the ruler to one side of the cube, and then let it tumble, rolling five times in a row, no more, no less, just to finish rolling one of the bottom edges of the cube.

"So, the side length of the cube is one meter long, and its volume is also a standard cubic meter?" Wang Qi thought as he pinched his chin and stared at the cube in front of him.

Of course, the measurement method of the ruler is very rough, and it can only be accurate to the millimeter at most. Whether the side length of the cube is exactly one meter long or not requires more detailed measurements.

However, this does not mean much. Wang Qi only needs to know the roughly precise volume of the cube.

Temperature, volume, and finally, pressure remains.

At noon, he didn't buy a piezometer in the haberdashery, so Wang Qi had to use a balloon to measure it, anyway, like the volume, he didn't need to know too accurately now, he just needed to know whether the cube was a vacuum or not.

He took out an uninflated balloon, inflated it, and tied a dead knot in the opening.

Wang Qi grabbed the balloon with both hands, but his eyes were intently looking at the cube in front of him.

"One, two, three, go!"

With his "go", the balloon in his hand disappeared at once, and then appeared in the cube in front of him almost simultaneously.

Then, with a "bang"—the sound was imaginary in his head, of course, but there wasn't really any sound—the balloon exploded, and it exploded into several pieces of rubber and scattered in the cube.

He had bought two balloons from the old woman, so he took out the one that was left in the cube and continued to blow it. In order to prevent it from bursting, this time it didn't blow up much, only a balloon the size of a small orange.

"One, two, three, go!" Wang Qi shouted in his heart, staring at the cube in front of him without blinking.

Then, as just now, the balloon in his hand disappeared, appeared in the cube in an instant, and then expanded rapidly, until it was the size of a papaya, and the tension of the balloon and the pressure of the gas in the ball reached a balance, and then it stopped.

"It's a vacuum, at least the air pressure is much lower than the real environment. "Two simple experiments allowed Wang Qi to basically understand the air pressure in the cube.

After the barometric pressure experiment is completed, there is still a small tail in the previous temperature experiment.

So, he took out the thermometer again and found that the thermometer, which was originally in the 80s, had dropped a lot after more than 10 minutes, from more than 80 degrees to more than 50 degrees.

"It seems that the temperature in the cube is really much lower, maybe it is the temperature of the real environment. When a high-temperature thermometer reaches a low temperature environment, it naturally radiates energy to the outside and lowers the temperature. ”

Temperature, volume, air pressure, through a rough experiment, Wang Qi has a further understanding of the properties of the cube, which makes him feel a lot happier.

Experiments on the basic physical properties of the cube are now almost done, and there is still one living experiment left. Through the discussion of the basic physical properties of the cube, he can now basically predict the consequences of throwing a guinea pig in it - weightlessness, vacuum, hehe, that scene, not too exciting, in fact, it is almost the same whether to do live experiments or not.

However, in the spirit of scientific exploration, seeing is believing, he still plans to go out later to find a living critter to throw into the cube, and see for himself the images that can only be seen in some science fiction movies:

A bloody and brutal spectacle of science!
