Just wanted to show off the rockin' bird feeder that I made today. I've been saving the bottles and formulating the design for a couple of days. Most of the how-to videos seemed too complicated, so I looked at a bunch of different pictures of various home made bird feeders and took ideas from a few of the simplest ones.
The bottle that is upside-down fits the neck of the larger bottle so that the bird seed can be poured from the top. Then, it will fall through the small bottle opening and build up a layer for the birds to eat from, being replenished from above as the seed is eaten. Tomorrow I need to pick up some seed to make sure it works as it should. Just need a wire or string to hang it up and viola.
