Make Your Own Snow Globe (12/3/14)

MATERIALS:

  • Glass jar with lid
  • Plastic figurine
  • Glue (hot glue or superglue works well!)
  • Glitter
  • Distilled water
  • Glycerin (optional)

INSTRUCTIONS:

  1. Decide what you would like to put in your snow globe. You can use any kind of plastic toy or figurine.
  2. Glue the plastic figurine to the inside of the jar lid, and set it aside to dry.
  3. Add some super sparkly glitter to the jar! You may need to add more glitter if you have a larger jar.
  4. Fill up your jar with water. You can also add a few drops of glycerin to the water if you would like. Glycerin helps the glitter float better.
  5. Tightly screw the lid on the jar.
  6. You can even decorate the outside of the snow globe if you would like! These homemade snow globes are perfect for gifts or decorating your home!

HOW DOES IT WORK?

Have you ever wondered what makes the “snow” inside a snowglobe fall down so slowly? It really does look like falling snow! One reason is the viscosity or thickness of the liquid, and another reason is the buoyancy of the  “snow.” Viscosity is a fancy scientific word for describing the resistance of a fluid to flow. It could be described as fluid friction, which is a resistance to motion. Buoyancy is the upward force of a fluid that allows objects to float in it.
