Idea: Photo Snow Globes

This is a great idea.
All you need to create your own unique snow globes is a bottle, photo, glitter, and corn syrup.

You could create a brand with thematic photos like sunsets or animals. If you plan to sell to a local store, for instance, take photos of the tourist attractions nearby then you will be making fantastic individual mementos/souvenirs for visitors.
Or just create unusual or odd snow domes using some of your more unique photos.
