Snow Globes refer to small, decorative spheres often made of glass, enclosing a miniaturized scene of some sort, frequently together with a model of a town, landscape or figure. The sphere also encloses the water in the globe so that it can be shaken to simulate snowfall and winter weather. As a collectible, these items vary in design, size, and theme, making them popular among collectors worldwide. Some globes feature holiday scenes, famous landmarks, or popular characters, and may play music or have special lighting effects.
