What to do with those 20 ounce pop bottles? Grab a couple of wooden spoons, a small threaded eye bolt with a nut, and some string. Use a knife to poke the holes for the spoons and the eye bolt, push the spoons through their holes and tighten the eye bolt with it’s nut inside the lid. Tie the string to the eye bolt, and fill the bottle with bird seed. And voila! A nice bird feeder that will attract the birds, feed them, and keep that plastic bottle out of the land fill!
