To know more about snow globes

Initially snow globes consisted of a heavy lead glass dome which was placed over a ceramic figure or tableau on a black cast ceramic base, filled with water and then sealed. The snow was created by use of bone chips or pieces of porcelain, sand or even sawdust. As they became more sophisticated, the glass became thinner, the bases were lighter (Bakelite was popular during the Art Deco period) and the snow was made out of particles of gold foil or non-soluble soap flakes although nowadays, for health and safety reasons, small pieces of white plastic are used. Later, the liquid was changed to light oil, then water with antifreeze (glycerin or glycol). An added benefit was that glycerin and glycol slowed the descent of the snow.

Today's snow globes can include music boxes, moving parts, internal lights, and even electric motors that make the "snow" move so that it is no longer necessary to shake the globe. Some also have central slots for positioning items such as photographs.

Beginning in 2005, many U.S. stores sell inflatable snow globes as part of their Christmas décor. These have a base with a blower, forcing air which carries styrofoam pellets from the bottom and through a tube up the back to the top, where they are blown out and fall down inside the front, which is made of transparent vinyl. The rest of the globe, including the characters inside, are made of colorful nylon fabric. These globes are typically large decorations for the front yard, and are lighted internally with a few C7 (nightlight-type) incandescent light bulbs (which are enclosed in plastic spheres to prevent heat damage to the fabric).

A variation on this is the "tornado globe", where small foam objects spin around inside a globe. This is more common for Halloween décor, where foam bats or sometimes ghosts may fly around the Halloween figures in the middle. These were most common in 2006, and come in both large inflatables, and smaller tabletop versions with rigid plastic globes about 8 to 12 inches or 20 to 30 centimeters in diameter. As with the snow globes, static cling often causes the foam to stick to the plastic (especially vinyl) when humidity is low, while condensation will do the same thing on outdoor inflatables when humidity is high, or rainwater has seeped in while it is deflated.
