A bird's feather has a distinct aerodynamic shape. I mean, I think it's aerodynamic.
Last month I was inspired by a bird's feather in the passenger seat of my car to construct a pinwheel out of feathers. Out on a hike with my kids, I challenged them to find five more bird feathers.
We collected almost exactly that number, a handful of feathers on the ground.
I didn't think the pinwheel would harness much power, so I tried to make a bearing that was low friction.
I hot glued the first feather to a short section of drinking straw.
The rest of the feathers followed. I set them perpendicular to the axis with a slight attack angle.
The wheel of feathers was extremely lightweight. I slid the straw onto a wooden skewer and added a steel nut to minimize the friction on the rotating straw.
Hot glue held it to another skewer post.
It worked like a charm! Outside it spun with the slightest breeze, and the kids took turns running through the house, watching it spin as the air rushed past.
The feather pinwheel is a really nice addition to my collection of authentic hemp dream catchers..at least it was until a stray cat hopped the fence and ate it.
Now, should I try building one out of eagle feathers, or should I try using butterfly wings?
