Air bubbles can also occur due to temperature fluctuations, i.e. also during transport. In some cases, some of the water in the globe will evaporate and small air bubbles will form on top of the snow globe.
Snow globes require incredibly unique engineering and highly specialized equipment to ensure no air bubbles and a durable, waterproof globe that will last a lifetime.
If your glitter floats to the top, you don’t have enough. If everything sinks to the bottom and won’t move when you shake the jar, you have too much. To save water, start small and add until you are happy with the float of your glitter.
Protect the snow globe from direct sunlight. The bullet acts like a magnifying glass and can cause a fire. Sunlight can also cause the water to discolour. Dust with a soft cloth.
Fill your mason jar about 75% full with distilled water. Then add 2-3 drops of glycerin. This will help thicken the water so the glitter will float more slowly – but don’t overdo it or it will get too sticky!
One of the secret ingredients in every snow globe is glycerin, a clear liquid typically made from vegetable oils and often used to slow the effects of shaken water and glitter from falling snow. Just shake it and everyone will love seeing the snow swirl inside.
If so, you can carefully drain the water and top up with distilled water using a turkey syringe. Older globes were made with water, but today almost all are made with a synthetic liquid – glycol (i.e. antifreeze). If your device is new, let a professional take care of the globe.
A good ratio is 1 cup water, 3 teaspoons glycerine, and 3 teaspoons glitter. Glycerin can replace olive oil, vegetable oil, or baby oil. As you add more oil, the glitter will fall more slowly. Tighten and tape the lid on the jar.
There are many ways you can substitute glycerin when bringing your homemade snow globes to life. Some glycerin alternatives include light corn syrup, mineral oil, baby oil, or a clear cooking oil. Conversely, you can also do without a replacement altogether!
Tinsel Glitter – After much experimentation, I found that tinsel glitter with larger particles works best for making DIY snow globes as it looks the most like snow when it is falls through the water.
