Lots of Bubbles mixed with phosphorus to create an extreme glow. Two green sea turtles swimming on top. EXTREME glow in the dark piece. Kids LOVE this! Hand Blown Glass that Glows In The Dark. The crystals or the white crumbs you see all over the coral is 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. Goes with any decor. Makes a unique gift.
Consider a LED light base will light up the whole piece, makes a great night light for kids! A little larger then a softball.
