<P> There are a couple of ways to put a small model ship inside of a bottle . The simplest way is to rig the masts of the ship and raise it up when the ship is inside the bottle . Masts, spars, and sails are built separately and then attached to the hull of the ship with strings and hinges so the masts can lie flat against the deck . The ship is then placed inside the bottle and the masts are pulled up using the strings attached to the masts . The hull of the ship must still be able to fit through the opening . Bottles with minor distortions and soft tints are often chosen to hide the small details of the ship such as hinges on the masts . </P> <P> Alternatively, with specialized long - handled tools, it is possible to build the ship inside the bottle . </P> <P> One variation of the impossible bottle takes advantage of pine cones opening as they dry out . In constructing the display, a closed, damp cone of suitable size is inserted into a narrow - mouthed bottle and then allowed to dry inside the bottle . </P> <P> Fruits and vegetables inside bottles are grown by placing a bottle around the blossom or young fruit and securing it to the plant . The fruit then grows to full size inside the bottle . </P>
