Hmm... at work, I've spun some of the metal arms that clothes are used to be hung on..
At home or out and about; clothes hangers, sticks, two arrows as doubles, bow, broom, fork, butter knife, USB stick on a chain, keys, hair ribbon, braids, bag, staff while still in bag

not many know what it is, clothing items, socks, rope (even got bored one day and made some meteors outta the rope

), scissors (spinning it around my finger, flicking it, then handing it to someone handle first)... Lots of things to spin.
