Snow globes are traditionally filled with water, which serves as the medium through which the "snow" falls. However, some snow globes, especially those from overseas, may contain a small amount of ethylene glycol (antifreeze) mixed in with the water. This is done to prevent the water from freezing during shipping, but ethylene glycol can be harmful if ingested. If a snow globe breaks, it is important to keep children and pets away while cleaning up the spill, and to dispose of any paper towels used to absorb the liquid. If someone ingests the liquid or gets it in their eyes, it is important to seek medical attention immediately. When making a DIY snow globe, distilled water is typically used, along with liquid glycerin or light corn syrup to slow the descent of the snow. Glitter is also added for visual effect.
