YET another reason bottle trees should be considered Bottle trees are said to capture evil spirits. Here is the legend at Texas Tin Lizard, "Evil spirits are drawn to the glow of colored glass, especially blue wine bottles. They enter the bottles and are trapped inside, consumed, and converted to goodness and radiant light."
Bottle Trees were put near the entrance to a house, so spirits did not enter with you. The spirits would become mesmerized by the play of the sunlight thru the colors of glass, and be trapped inside the bottles. the spirits are trapped in the bottles & said to be destroyed when the sun comes out the next morning. This is what I need to do with my next installment of blue Vodka Bottles, right?
