It’s actually 100%. I voted for the “dome” because as I was looking at the poll at work someone came up behind me and it seemed right and I clicked quickly so as not to arouse coworker’s suspicion! It’s globe! Snow globe!!
It’s a snow dome, of course.
It’s not even close to looking like a Rhombicosidodecahedron.
I voted “snow dome” in general, because the ones I remember from my childhood were dome-shaped. The one in the pic might be more accurately described as a snow globe, of course. Haven’t seen one in years.
I wish I could remember what i heard it being called for England or Australia just a couple months ago. It sure wasn’t snow globe like the USA.
This isn’t the one I was trying to think of, but I’ve heard it called glitter dome too. I’ve heard a lot of those names you listed, but rarely anything but snow globe.
Much like everyone here, I’ve never ever heard it called anything other then “Snow Globe”.
We always called them globos de nieve.
Could it be ‘Snowstorm’? That’s what I used to know them as, but the term has largely been supplanted by ‘snowglobe’ now.
Me too! I quickly grabbed the first thing that popped into my head, then regretted it. Damn. Change my vote to snow globe too, please. 
Snow globe.
Even though the ones I had weren’t always globular, they were still called snowglobes.
“Snow Globe”.
I’ve also heard “snow globe” applied to the ones that contain glitter.
I was just about to start this thread in Comments on Cecil’s Columns, because I simply could not fathom calling it anything other than a snow globe. I’ve never heard it called any differently (or seen it labelled any differently, in tourist shops) anywhere in the English speaking world.
I call them ‘kitschy’.
I’m in England and I’ve always heard it called a snow globe.
I wish you would have allowed two choices, because I use snowglobe and waterglobe interchangeably. We sell lots of these where I work…they are a huge section of our store, and they are referred to as waterglobes (most likely because they have the glittery stuff, not the snowy stuff, inside. But I’ve used both terms my whole life, and occasionally snowdome for the small plastic ones sold at tourist traps.
