6．Gordon's hobby may seem strange to us．He likes building model ships inside old bottles．
Gordon has always loved ships，especially sailing ships from the old days．His interest was made many years ago when he visited a museum in Ottawa，Canada，where model ships in bottles were displayed（展示）．Gordon regarded it as a wonderful show．At the same time an idea came to his mind．How did the craftsman（手艺人） get the ship through the narrow neck of the bottle？Gordon decided to make a research．
He found an old craftsman who was glad to teach him the basic skills．First，Gordon takes an old bottle．Then he puts in a layer of paint，carefully shaped and painted to look like the sea．Next，he builds the ship．To get the ship through the neck of the bottle，Gordon folds（折叠） down the masts（桅杆）．Once the ship is inside the bottle，he takes a long，thin tool to raise the masts．
Gordon has completed more than one hundred models．His aim is to build up aircraft carriers（航空母舰），buses，cars，airplanes，houses，and many other kinds of models inside the bottles．This will be more challenging（挑战），as he will have to build actually inside the bottle．His hobby certainly needs time，patience and a steady （平稳的）hand．
