Snow globes, also known as water globes or snow domes, are small decorative paperweights often sold as commemorative novelties or personalized gifts. Most snow globes contain small flakes of white plastic to simulate a snow fall whenever they are shaken. Some snow globes, however, may contain bits of glitter or small plastic representations of real objects such as dollar signs or musical notes. The "snow" in snow globes usually falls over a holiday scene, a personalized photograph or a popular tourist destination.

Snow globes are thought to have been developed in Europe during the late 17th or early 18th centuries, perhaps as a variant on the decorative and functional glass paperweights popular at that time. Early snow globes were made from leaded glass formed into the shape of a dome. The "snow" may have been pieces of bone or shards of broken porcelain. These snow globes often featured very detailed and well-crafted scenes of castles or picturesque cities. The bases for these snow globes might have been made from the finest ceramics available. The snow globes would be filled with distilled water and a sprinkling of fake snowflakes, then sealed with the base permanently.

Eventually the expensive process of molding leaded glass for snow globes gave way to a more inexpensive production process using thinner glass. These less-ornate snow globes became very popular souvenir items, finally reaching the American market by the 1920s. Snow globes, particularly their bases and scenery, were also created from an early commercial plastic called Bakelite during the 1930s and 1940s. These snow globes are highly prized by collectors of Art Deco decorative pieces.

Modern snow globes may be made from materials ranging from leaded crystal to cheap plastic. Elaborate snow globes often have carved bases, music box mechanisms and interior lighting effects. Tourists looking for keepsakes or gifts, however, are often presented with cheaper plastic snow globes mass produced in places such as China or Singapore. There are still artisans, primarily in European countries, who specialize in creating high-end snow globes for discriminating collectors.

Homemade snow globes can be constructed from clear jars with watertight lids, insoluble soap shavings or glitter, small plastic objects and a hot glue gun or florist's clay. The scene or photograph should be small enough to fit within the circumference of the jar's lid. The scene should be attached to the lid with florist's clay or a waterproof hot glue. The jar should be cleaned thoroughly, then filled with distilled water or mineral oil and the snowflake material, leaving a small gap to prevent overflow. The lid containing the scenery should be screwed on completely, then sealed with a bead of hot glue around the rim.
