Soda bottle bird feeder
A favorite of the elementary school classroom, the soda bottle bird feeder is a simple DIY project for bird lovers of all ages. After rescuing a 1-2 liter soda bottle from the recycling bin, look around your house or yard for two wooden spoons, dowels or twigs you can use for the project; these will create a place for the birds to sit while they eat.
Then follow the instructions on BirdFeederPlans.org to cut small holes in the bottle where you will insert the spoons or dowels; parents will need to help their kids with this step. Fill the bottle with bird seed, twist the cap back on and then hang the bird feeder from a tree or porch with string or fishing line.
