Picture an empty wine bottle with a cork secured at the top in the usual way. Inside the bottle a metal ring hangs suspended by a string. How is it possible to make the metal ring drop to the bottom of the bottle without touching the ring, the thread, the cork, or the bottle while leaving the cork in place and intact?
设想一个空酒瓶,瓶口被软木塞以正常的方式塞住,瓶子里一个金属环悬挂在一根细绳上。在不接触环、细绳、木塞和瓶子,不移动木塞的位置,保持瓶子完整的情况下,怎样才能让金属环掉到瓶底呢?
