Beer bottle bush. Truck wheel used as base. The stalks are 1/4" rebar (pencil rod steel). Of course I had to empty the bottles before I could use them on the bush. Waste not, want not. Welding done with a Millermatic 211. When the wind blows, the bottles hit against the stalks and sound like a wind chime. My wife really loves the sound...and is the world's most tolerant women for letting me put my stuff in our front yard. Obviously we are not in a deed restricted community.
