And their contraptions (LOL) could help others in need if they could package and market them. ;-) You should see some of the welded messes some of my family members have come up with. They’re...um...embarrassing. ;-)
My dad's bird feeder is as entertaining as a Rube Goldberg machine. He installed it on a wire between two trees right outside the dining room window, so that we can have a Squirrel Floor Show while we eat. It's like a Yankee Flipper, only operated by counterweights and vertical instead of horizontal. . . .
We thought about getting a patent for it, but it would cost WAY too much to manufacture -- too much hand work involved.
