the film here so you can get a very interesting experience. I want you to see how this illusion is constructed, and it's going to rotate so you see that it's inside out. Now watch, as it rotates back, how quickly your perception snaps. OK now.
フィルムを回すと面白い事が経験できます 錯覚がどのように起きるのか良く見てください 回転させます　すると 裏返しになります　よく見てください　回転して 元に戻ります　すぐに意識が変わります
