I have always had a nostalgic fascination with snow globes, and my kids have recently become similarly enamored (I think it happened when my husband brought back a miniature one from a business trip to NYC with the Statue of Liberty and the Empire State Building in it.) So when I saw an image on Pinterest of some beautiful globes, I knew we had to add it to our holiday activity list. Now, I will be honest - snow globes rank rather low on the No Mess scale (there is glitter AND water involved, after all.) And ours did not turn out quite as lovely as those for sale at the mall or made by Martha Stewart. But the kids and I had a grand time designing them. I think we've got a new tradition on our hands. The Pinterest image didn't have a source, so our approach is based on a hodge-podge of sources I found online / YouTube, plus a little trial & error. Learn from my mistakes!
Once you all feel good about the arrangement of your scene, you can super glue the figurines to the lid. (I just love the assemblages: Empire State Building + Eiffel Tower + Leaning Tower of Pisa, Santa + Taj Majal + Arc de Triomphe and Big Ben + Statue of Liberty!)
You'll want to let them dry for long enough to be sure the glue will hold. In the meantime, you can add water to the jars - fill them not quite to the threads to start (the figurines will take up space when you put them in.) Then add the glycerin - about a half-teaspoon, and the glitter - about a teaspoon. You'll see we added quite a bit more than that - some of us MAY have gotten carried away when given free rein on the glitter. Then carefully screw the lid back onto the jar. You might want to do this over the sink in case there's too much water in the jar when you put the figurine in. You can also check to see if you need to add a bit more water.
