Assemble the AWM sniper rifle with a neutral pen, with 90% ultra-high simulation and firing capability, which can be done in school. ”Recently, in a video displayed on a social media platform, it can be seen that three ordinary neutral pens were disassembled into parts such as pen holders, springs, pen refills, and pen caps. With the blogger's reassembly, a mini "pen gun" was completed in no time. Using the keyword 'make a gun with a neutral pen' for search, the most popular video in the search results has received over 400000 likes and over 10000 comments. In the eyes of some people, students playing with "pen guns" in school have nothing to worry about. Some tutorial videos specifically indicate in their titles and introductions that they can be done in school. Some netizens believe that the easy availability of materials and convenient production are important reasons for the popularity of this "DIY weapon" among minors, and even some comments jokingly say that "the success rate at home is 1%, and the success rate at school is 100%". There are also videos claiming that this is a stationery transformation that is "fun and harmless", implying that the "pen gun" is both safe and highly entertaining. Easy to learn and do, coupled with fun, has led to more and more students participating, which is an important reason why "pen guns" have quickly become popular on campus. The components of the 'pen gun', although derived from a pen, to some extent possess the attack and damage capabilities of a 'gun'. If used improperly, there is a certain degree of danger involved. The finished product of a "pen gun" usually uses the pen core as a "bullet", with a range of about two meters, which can easily knock down plastic bottles. Such destructive power can cause injury or even disability. As a matter of fact, according to public information, there have been cases where a boy's homemade pen refill was ejected through his own cornea, and there have also been accidents where a boy's palm was ejected by a classmate's "pen gun" and inserted into the pen tip. One of the students had a corneal rupture caused by a "pen gun", requiring emergency corneal suturing surgery, and their vision dropped to 0.2 at one point, resulting in a second degree disability assessment. Similar cases should be highly valued by teachers and parents. The harm of 'pen and gun' to students' physical and mental health may far exceed the risk of injury. By transforming stationery into "weapons" and simulating shooting games, students are prone to confuse aggressive behavior with "fun" and "creativity", leading to recreational and violent activities during break time. Some students use "pen and gun" as social chips to show off their modification skills or initiate battle games to gain peer attention, which may breed a competitive mentality and aggressive personality tendencies. Making a 'pen gun' requires repeatedly disassembling stationery and adjusting parts, which may evolve into addictive behavior and occupy learning time and energy. According to the Law on the Protection of Minors, it is prohibited to produce or publish online information that promotes violence and other harmful effects on the physical and mental health of minors. The Measures for the Administration of Internet Information Services clearly stipulates that network information content producers should guard against unsafe behaviors that may cause minors to imitate. To address the chaos of 'pen and gun', platforms should improve their content review mechanism, use AI technology to accurately identify and remove dangerous modification tutorials, and take measures to restrict or ban illegal accounts. Relevant departments and stationery industry associations should target the safety hazards of "pen guns" and similar modifiable stationery, promote the modification, optimization, and improvement of production standards, and eliminate the adaptability and feasibility of ejection type modification of stationery components from the source. Schools need to include stationery safety in their themed class meetings, demonstrate potential risks through case studies, and strengthen inspections during breaks to promptly prevent dangerous behavior. Parents should guide their children to establish a correct concept of stationery use and avoid the misuse caused by bulk purchase of neutral pens. Only through multi-faceted collaborative governance can we weave a dense campus security protection network. In recent years, there have been numerous bizarre gameplay styles on campus, such as "toothpick crossbow" and "cigarette card", which have become popular. "Pen gun" is the latest manifestation of such gameplay styles. Therefore, the governance of "pen and gun" should not only be dealt with and dealt with on a case by case basis, but also consider why bizarre gameplay occurs in turn, and from a global perspective, treat it as a dangerous phenomenon to strengthen rectification and guidance, so as to avoid bizarre gameplay from appearing in various ways on campus.
