We're gonna make a cheap and funky weather vane, aka a wind vane, in the shape of a canoe paddle. Gather your materials from your junk bins and follow along.
Step 1: Parts is parts
Find a fan, a length of pipe and some scrap wood.
Step 2: Remove the fan blades
Cut away the fan blades to fit your pipe.
Step 3: The rotating parts are done
This is the essence of your easy rotating wind vane.
Step 4: Assemble and fly
Some screws, a couple of nuts and bolts, and you're ready for the wind.
