質問：アルミホイルで電磁波は本当にカットできますか？

I was curious to see if aluminum foil could block electromagnetic waves, so I tested various things, such as whether it really does have the effect of blocking electromagnetic waves, whether there is any difference depending on how it is wrapped or the material, and whether there is a difference depending on the frequency of the electromagnetic waves. I also tried out some highly effective electromagnetic wave blocking methods to identify problems and explore ways to block electromagnetic waves effortlessly in everyday life. There were some surprising results, so please read to the end. On the Effectiveness of Aluminum Foil Helmets: https://mozai.com/writing/not_mine/al...
