She said her dad had rigged up a small light bulb underneath the basin in his wife's birdbath which kept the water warm enough that it didn't freeze.
So she found a small bulb and jammed it up inside the pedestal under the water dish with some aluminum* foil.
She added some duct tape to keep everything in place, ran the wire out the bottom of the pedestal, connected it to an extension cord which was connected to another extension cord which was plugged into an outdoor socket.

*Have you noticed some of the cooks on the Food Network saying they used some "tin" foil in a recipe. I think it's all aluminum these days.
