Novel Idea- Light Bulb Hanging Vase

In my boredom of internet searching I came across this creative photo. I'm a crafty person and love the design of this. For the work, though, I don't think I'd put real flowers in the bulb. I don't have enough wildflowers around my home to keep it stocked. As an alternative, i would place some pebbles at the bottom and use some fake flowers from a craft shop. The water in the bulbs would evaporate & leave a ring in the class that cannot be cleaned. My way allows for minor dusting but otherwise I can forget about it. Still, it's a great idea for some creative decorating (one might say a "bright idea"... you know you were thinking of that, too).
