What are these? Sorry the photo is not great.
They are fuzzy little cottonballs about 3/16" round. At the tip seems to be a small fan, much like a featherduster in miniature. The fan is only about 1/16".
Thanks Chucker, I thought it was a sponge and so did my wife. BUT sponges don't have little fanworm fans and these do. Maybe I'll bring my EOS home for work and see if I can't get a macro shot.
