We've noticed a lot of birds out during the last few mornings, and decided to make a little bird-feeder from water-bottles for them! It's a very easy and fun project, though it does require some supervision. Depending on your children's ages and attention spans, you may even want to pre-cut the bottles for them.
For you visually-oriented people, here's a diagram of the entire process:
If you want a step-by-step, here you go:
1. Prepare the bottles. Cut the flat bottom off of Bottle 1 and save it for a lid. Cut the pointed top off of Bottle 2 and recycle it (or throw it away...sigh). From Bottle 2, cut two holes near the bottom for a stick to go through (see diagram) and two holes to use as doors (about an inch above the stick holes--see diagram).
2. Thread a long piece of yarn through the doors to use as a hanger. Make sure it is not in the way of step 3.
3. Squish and slide Bottle 1 (Tip A first) into Bottle 2 until Tip A is below the bottom of the doors.
4. Fit a stick through the holes for the birds to sit on.
5. (Everyone's favorite part!) Pour birdseed into your new bird-feeder! Squish the lid on and find a cool spot to hang your new bird-feeder! It may take a day or two for the birds to find your feeder, but they will come! Try to learn the names of all the birds who come to visit!
