摘要：

摘要：经过我们多次在不同的生活环境进行的实验操作，发现透明塑料袋装水加硬币驱赶苍蝇的原理是因为透明水袋有凸透镜的作用，光线在透过“凸透镜”时一定会对周围的光强、温度产生改变，而这种变化正好刺激了苍蝇的某种敏感器官，最终研究出圆形透明水袋加硬币可以有效的驱逐苍蝇。【更多...】

Abstract:

To examine whether a transparent water bag with coins can repel flies, the research group conducted comparative observations in a rural kitchen. The study compared bag color, bag size, and coin color, and then carried out application observations in a cured meat shop, a cooked food shop, a restaurant, a kitchen, and a pigsty. The results showed that red and black water bags had no obvious effect, while transparent water bags reduced observed fly activity after 60 minutes. A larger transparent water bag appeared more stable than a smaller one. A round transparent water bag containing silver-colored coins showed no obvious fly landing at 30, 60, and 90 minutes. The method is low-cost, easy to operate, and non-toxic. Its possible mechanism may be related to light refraction and reflection from the water bag and the reflective effect of coins. Further repeated trials and quantitative records are needed to improve reliability.
