Selling a Seattle snow globe, with Pike Place market and the Space Needle in the background, wouldn’t make much sense: it just doesn’t snow here that often. Someone sells a glitter-filled snow globe and calls it a rain globe, but it should be possible to use some sort of oil that’s denser than water and dyed blue. You could shake it, so that the oil breaks up into tiny droplets, and watch them puddle at the bottom of the globe, right in Elliott Bay.
