上小学时,有时在洗澡时会泡在浴池里喝瓶牛奶,那时的心情别提有多美了。喝完牛奶,把装牛奶的瓶子洗干净,再装点儿水进去,使其倒立着在浴池里浮着。如果搞得好,能使牛奶瓶的瓶底擦着洗澡水的表面浮动。但不管怎么努力,从来没能使它像潜水艇那样在水中间浮动。现在想起那时的情景,便试着作了这么一个有点奇怪的玩具。 When I was in elementary school, I sometimes drank a bottle of milk in the bath when I was in the bath. After drinking milk, the bottle of milk to wash clean, and then loaded some water into it, it stood upside down in the bath floating. If done well, can make the bottled milk bottles rub the surface of bath water floating. But no matter how hard it worked, it never floated in the water like a submarine. Now think of the scene at that time, he tried to make such a little strange toy.
