Palming keys is fun...and erasers when i'm at school. lol.
Just a little something I remembered: JB Bobo could apparently backpalm about 20 coins and produce them one by one.
i like to use the paul harris rear palm whenever possible.
but as far as other objects, you can do pen's, sharpies, jumbo coins, lighters, rubix cube's, camera's, wallets sometimes, watch's, i can go on.. i love palming things off people or onto them.
