You can stretch out a strand and make it follow your magnet, you can polarize your putty to work as a magnet itself, and then there's the classic of placing the magnet directly on the putty and watching it envelop the magnet. There's plenty of fun to be had, check out the video I made with some of the fun you can do.
Putty has been known to leave a residue on some surfaces, even more so with the iron oxide powder. Use caution when playing with your magnetic putty.
If you get magnetic putty stuck to fabric you can try placing the magnet on top of the fabric and the putty may work it's way out (wait 24 hours). Alternatively you can apply rubbing alcohol to area and work out the putty, try a concealed test-area first. WD-40 may also work. If all else fails, take the fabric to the dry cleaners and tell them it's a silicone-based stain.
