First I made two fan blades out of plastic coated cardboard. I then stuck thin long pieces of sponge on the edges. I realized that they were okay as prototypes but they were not functional.
Since we could not experiment on a ceiling fan, we bought a table fan and dismantled the cage. I cut up long thin pieces of the yellow “scotch brite” and stuck them in a line on the edges of the fan on both sides, the back and the front. I used a paint brush to dampen the sponge slightly and then turned it on. It worked.
