Red flower with three blue dolphins on top and an ocean blue bottom. Hand Blown Glass that Glows In The Dark. The crystals or the white crumbs you see in the middle of the globe are phosphorus. When phosphorus is exposed to the light during the day, it will glow at night for an hour or more depending on how bright the day has been.
Consider a LED light base will light up the whole piece, makes a great night light for kids! A little larger then a softball.
