摘要：A lighter than air toy consisting of a basket gondola made of a light plastic or other material attached to the bottom of a toy balloon filled with a gas less den than air, such as helium. The balloon, when inflated with a gas less den than air, provides the buoyancy to lift the gondola into the air and allows it to ri freely or float at a predetermined level. Ballast weights can be added to the gondola to balance the buoyancy force so that the force of gravitation on the gondola and balloon is exactly balanced by the buoyant force whereby the gondola and balloon asmbly together have a neutral buoyancy in the air. The basket gondola and balloon are held together by means of stretching the knot of the balloon through a keyhole slot made in the basket gondola. The knot is held in place by wedging it into the thin part of the keyhole slot. This invention is simple to make and put together. The basket gondola can be ud as a childs toy or for advertising promotion.complicated是什么意思
