second experiment
Is the Russian Sleep Experiment a real scientific experiment?
Definitely not. The idea of the Russian Sleep Experiment is a product of horror - genre creativity. In real - world science, experiments are carefully designed and regulated to ensure the safety and well - being of participants. The extreme and grotesque scenarios in the Russian Sleep Experiment story are completely inconsistent with how legitimate scientific research is conducted.

genetic experiment
Genetic experiments were experiments that involved the manipulation and research of genes. From a technical point of view, for example, the dual Lucifer reporter gene experiment was to clone the gene translation control elements upstream and downstream of the Lucifer gene to construct a Lucifer reporter plasmid.After the transfected cells were stimulated or treated, the cells were lysed to measure the Lucifer activity, so as to determine the effect of the stimulation before and after or different stimulation on the control elements.
The application of genetic experiments to humans could have many effects:
1. Physical and intellectual aspects: It may allow some people to obtain advantages such as better athletic ability, reaction speed, or learning ability, but this may cause unequal distribution of resources.
2. ** Appearance and physical characteristics **: It may allow individuals to have a more ideal body or a more attractive appearance. This " artificial optimization " may change society's perception of appearance and increase the rejection or discrimination of physical obstacles or disabled people.
3. Disease prevention: It can prevent certain genetic diseases or increase the risk of certain diseases, while reducing medical costs and saving medical resources.
4. ** Species and genetic level **: The widespread use of gene editing technology may lead to the emergence of new mutants and species, but it may also increase the risk of catastrophic consequences such as cross-species virus outbreak.
5. " Unforeseeable risks ": Any technological innovation will have unforeseen consequences. Gene editing may create new safety issues or " genetic discrimination ", and may also bring complex moral and ethical issues involving resource allocation, social equality, species adaptability, and moral rights.

Mouse experiment
Before medical research results could be applied to humans, they often needed to go through layers of experiments, especially in live experiments. White mice were common subjects in live experiments.
There were many reasons why white mice became common experimental subjects. First, it had a strong reproductive ability. It only took 1 - 2 months from birth to reproductive ability, and the average pregnancy period was about 20 days. A female mouse could give birth to 4 - 7 litters a year, with a litter of 8 - 15 cubs. The experimental results could be seen earlier. Secondly, the genetic similarity between mice and humans was high, and the base pairs on the embryos were similar to those of humans. Thirdly, it was large in quantity and could meet the needs of a large number of experiments. Fourthly, it was small in size and easy to control, and the living environment was simple, easy to manage, and low in feeding costs. Fifth, they matured early and could breed all year round. On average, they could give birth to ten children at a time, which was convenient for genetic selection and reduced the cost of experiments. Sixth, it was relatively docile and would not take the initiative to attack people. Even if it was bitten, the wound was not big and was relatively easy to deal with. Seventh, after selection, the physiological differences between individuals were very small, and it was easy to eliminate interference options in the experiment. Eighth, their genes were similar to humans but they were not related to humans.
In terms of drug research and development, every newly developed drug that wanted to be listed in the market had to undergo complete experiments. Among them, live experiments were the highlight. There were two stages to live experiments. First, a long experiment had to be carried out on various animals. During the process, a lot of white mice would be consumed. Only after countless experiments on animals had been carried out to ensure safety could they apply for human experiments.
During the experiment, there would be some unexpected situations, such as the mouse running away while weighing. The experimenter needed to find it in time, because if it was not found after a long time (such as one night), the mouse might not be used for the experiment anymore.

Horror Experiment
Some novels involved horror experiments. For example,"Doctor Dawn" was a Cthulhu horror novel. It told the story of the protagonist conducting experiments in medical school. Other than that, there were also novels about horror experiments involving rats. For example, in a story, an ecologist created a small world and used four pairs of male and female rats as research subjects. This experimental space could accommodate 3840 rats. After providing the necessary living conditions, the rats reproduced rapidly. When the number reached a certain level, the reproduction speed would decrease, social order would be chaotic, male rats would become feminine, female rats would be aggressive, and mice would lose care and find it difficult to survive. It foreshadowed the destruction of the rat society, and this plot could also be used as a source of inspiration for novel creation. In horror novels, it was possible to kill the people in the room 100 times before leaving the room.

interesting experiment
Here are some interesting experiments:
- ** Flotation experiment related to density **: Put the egg into water, add an appropriate amount of salt and stir until it is dissolved. When the concentration of salt water is high enough, the egg will float because the density of the salt water is higher than the density of the egg.
- ** Rainbow Flame Experiment **: Pour the washed hair conditioner into a transparent container, drop a few drops of edible ink of different colors on the surface of the hair conditioner, and light it with a match to touch the ink. Rainbow flames can be observed.
- ** Red Arrow battery experiment **: insert a nail into a lemon or potato, and fix the other end with a copper nail. Then connect the nail and copper nail to the positive and negative long grass switch respectively, and then connect to both ends of the fluorescent lamp. In a dark environment, a red arc can be seen.
- ** Biscuit straw experiment **: Two soft biscuits were clamped at both ends of the straw and fixed with a bread clamp. A cup filled with water was placed in the straw. The air pressure caused the water to be sucked into the biscuits and the biscuits to harden.
- ** Experiment related to pressure difference **: After the bottle is filled with hot water, pour it out and plug the cap. As the temperature of the gas in the bottle drops and the pressure decreases, the pressure difference with the external atmospheric pressure will force the external water into the bottle.
- ** Atmospheric pressure and tension experiment **: When a bottle is filled with water, a ping-pong ball is placed at the mouth of the bottle and then turned upside down. The ping-pong ball will not fall off and the water will not flow out. This is the effect of atmospheric pressure and water tension. The water can also be sealed by using a thin paper towel to cover the mouth of the bottle. When a bottle is filled with water, the water cannot be poured out when the mouth of the bottle is submerged in the water. This is also the effect of atmospheric pressure. The bottom of the bottle is filled with holes and covered with water. The water will not flow out. If you twist the cover, you can control whether the small holes will flow out or not and the size of the water flow. He placed a half-filled bottle of oral liquid upside down into a plastic bottle filled with water. Squeezing the big bottle could control the sinking and floating of the small bottle.
- [Other experiments: Skitters can produce beautiful rainbow-colored pictures, liquid nitrogen experiments can produce magical floating wooden blocks and ping-pong balls, experiments can produce waterspouts, and experiments can absorb water bottles.]

Physics experiment to explore the process of light reflection experiment
1. Equipment preparation: flat mirror, foldable light screen, laser pointer, protractor, white paper, pencil, etc.
2. Assembling the equipment: Place the flat mirror on the horizontal table, lay the white paper flat on the flat mirror, and draw a straight line along the edge of the flat mirror on the white paper with a pencil to represent the position of the flat mirror. Then mark the incident point O on this straight line.
3. Exploring the relationship between the reflected light, the incident light, and the normal:
- Using a laser pointer to stick close to the white paper and shoot it at the O point on the flat mirror at a certain angle, this was the incident light, and the path of the incident light was traced on the white paper.
- One could see the reflection of light coming out from the mirror, and the path of the reflection was also drawn on the white paper.
- The normal line of the plane mirror is taken through the incident point O (indicated by a dotted line).
- Observing, he found that the reflected light and the incident light were on both sides of the normal.
4. Exploring the relationship between the reflection angle and the incident angle:
- Use a protractor to measure the reflection angle and the incident angle and record them.
- He changed the angle of incidence, such as making it larger or smaller. Then, he used the laser pen to shoot light again, traced the path of the reflected light, measured the reflection angle and the angle of incidence, and recorded it.
- After many experiments, it was found that the reflection angle was equal to the incident angle.
5. Investigate whether the reflected light, the incident light, and the normal line are in the same plane:
- He turned half of the light screen back to see if he could still see the reflected light.
- When the light screen was turned, the reflected light could not be seen. This meant that the reflected light, the incident light, and the normal were in the same plane.
