1. Make four small holes in a plastic bottle. Don't forget to make them perpendicular to each other.
2. Feed through the wooden spoons.
3. Slightly enlarge the holes that open up to the "bowl" end of the spoons so the seeds "feed" out.
4. Fill bottle with bird seed.
5. Hang above a container to collect bird poo.
6. Use bird poo in compost or as a fertiliser.
Bird poo is rich in nitrogen and phosphate, essential ingredients for leaf and stem growth.
