A snow globe is a decoration that is a transparent sphere, usually made of glass, enclosing a miniaturized scene of some sort, often together with a model of a landscape. The sphere also encloses the water in the globe; the water serves as the medium through which the "snow" falls. Some decorations fill with air and blow the "snow" to appear like a snow globe. The neighbors to May Parker had a blow up snow globe in their front yard. During their battle, Spider-Man said he would treat Mysterio's dome like a snow globe.
