Pop bottle bird feeder

My wife loves to see the birds outside her office window. I made this bird feeder so she could hang it outside. It was kind of a pain in the butt to fill so I designed a funnel that screws onto the top of the soda bottle and allows you to fill it easier.

To hang it you get a soda bottle of your chaice and drill a hole in the bottom. Fish a piece of string through the hole and tie a loop in it to hang it. The base is wide enough to set it on a flat spot also if you don't want to hang it.
