Introduction: Eco Friendly Bird Feeder

There are always those annoying, scavenger-like birds lurking near by in your backyard or by your home.  By using materials that you would usually throw away, you can now solve that problem by creating a bird feeder within minutes!  With this bird feeder, the feed will fall out through the holes created, creating a plate of feed to any birds!

Step 1: Gather Materials

1. One 2-liter bottle 
2. A plastic plate (hard plastic)
3. Dremmle(or any other small tool used to cut plastic)
4. Drill
5. Nails to fit in drill
6. Hot glue gun (and glue, plugged in and ready to use!)
7. String (smaller the better, but not easily broken!)
8. Thick and dark marker
9. Funnel
10. Bird Feed (can be actual bird food, or even crushed up grains and seeds!)
11. Newspaper to lay down on the table to keep it from getting stained or ruined
***OPTIONAL: paints and other decorative supplies to personalize and decorate your bird feeder!

Step 2: Drill Three Holes in the Bottom/side of Bottle

To start off this bird feeder your going to need to drill out 3 holes on the side/bottom of the bottle. Using a Drimmle we cut out oval like shapes on the bottle where the feed can now come out of. Tip: hold the bottle on a flat surface. With the Drimmle hold it against yourself for more control, and start to trace the outside of the oval. Once you have completed the outside of the oval, the center should of fallen out by now. If not, carefully pull the center out. BE CAREFUL!!! IT WILL BE VERY SHARP AND POSSIBLY HOT.

Step 3: Drill Three Holes on the Bottom on the Plate

Since we used a 2-liter bottle, we picked three of five bottoms and drilled holes through the bottom of the bottle, and the plate. Tips: using a black colored marker, make dots on the bottom of the bottle where you will drill, and press the bottle down on the plate. When you lift up the bottle, you should of created three black dots. The dots are to help you figure out where to drill the holes.

Step 4: Screw in the Screws Through the Plate Into the Bottle

Now you'll want to attach the plate to the bottle. With a drill, drill the screw through the bottom of the plate (where your three holes are at) into the bottle. Once you've done that, the bottle should now be attached to the plate.Tips: to insure stability, use a normal screw driver and tighten the screw as much as possible.

Step 5: Hot Glue Around the Base of the Bottle

Once you've drilled all the holes, its now time to help secure the bottle to the plate. Using a glue gun, hot glue around the bottom of the bottle. This will help plaster the bottle to the plate. Tip: Try to glue under the bottle as much as possible as opposed to the outside of the bottle.

Step 6: Add the Hook to Cap

You'll want to be able to hang your bird feeder.  In order to do that, you'll need to add a hook into the cap. Using your drill, drill a hole into the top of the cap that is the size of the screw part of the hook. Once you've drilled your hole, you will need to use a screw driver and screw in the hook (or, if easier, you can twist the hook to secure it in the hole). Tip: once you have inserted the hook into the cap with your drill, you'll want to use a screw driver and tighten the hook as much as possible to prevent the hook from becoming loose.

Step 7: Filling Up the Bottle With Bird Feed

Congratulations! You have successfully created this 100% recycled bird feeder, but its not a bird house until you add the bird food! Using a funnel, carefully unscrew the cap and insert the funnel into the top of the bottle. Next, using any type of bird feed, pour the feed into the bottle.  Since this is made of 100% reusable materials, by crushing up old cereal and other grains, you can create bird feed without having to waste any money at all! Tip: Have one person hold the funnel and bottle while another person pours the food into the bottle.

Step 8: Hanging the Bird House

Now that you have filled your bird house with bird feed, it's time to add the string. The string will allow you to hang your bird house where ever you please. With any type of rope/string, carefully tie a knot around the hook until the string is secure. Once you have tied your knot, you are free to hang your bird house! Tip: using smaller string is always a better option. By using the smaller string, the knot is more secure and the hook is less likely to slip out of the string.

Step 9: **OPTIONAL** Decoration

This step is completely optional, but if you would like feel free to decorate your bird house. We decorated this bird house by taking off the wrapper, and painting the bottle with an assortment of colors. We also used glitter to decorate the bottom of the plate! The paint we used has a glittery/metallic type shine to it, which is helpful when trying to attract birds to your bird feeder. Tip: wait for the glue and paint (or whatever you have used) to try before putting up your bird feeder.

Step 10: How Is This Eco Friendly?

Our project is very eco-friendly!  By recycling plastics, such as the plate and bottle, they are melted and used for making pillows, recycling bins, carpeting, etc. There are over 7 billion pounds of plastic thrown out by Americans each year.  There are about 6 2-liter bottles in each pound. By multiplying 7 billion by 6, you get the amount of 2-liter bottles thrown away by Americans each year, which is 42 billion 2-liter bottles wasted each year.  By simply recycling or reusing every liter bottle you have, we can save 42 billion 2-liter bottles!  
A 2-liter bottle has a volume of 2000 cubic centimeters. If Americans were to step up our game in recycling 2-liter bottles, we can save so much!  By using the equation (2000 cubic cm)x , we calculated how much room we could save in a landfill.
100 bottles: 200,000 cubic cm
500 bottles: 1,000,000 cubic cm
1000 bottles: 2,000,000 cubic cm
5000 bottles: 10,000,000 cubic cm
