That's what I ended up finding out as well. It wasn't expensive, but it was neat...kind of like a pencil-topper but with tiny gold flakes in it and a real glass globe. It was literally small enough for me to swallow, if not for the base.

More like a big marble really.

So I wonder if they outlaw all snowglobes becasue they truly believe that there's no way to really tell how much liquid is in them? Surely if it was a liquid volume thing they could just have a restriction on diameter.

3.4fl oz is just over 6 cubic inches, which means that a snowglobe with a diameter of 2.26 inches is kosher.

To be safe, they could just say no snowglobes over 2 inches.

But then that means measuring, so maybe it can't work...
