This is one of our favourite toys in the office. It's not unusual to see several of these balls flying, squadron like, around the office. Having a stress ball fight from behind the t-shirt rack is certainly a great way to relieve stress.

My favourite trick is the lob and piff: using your left hand, lob up a high ball, your target should get look up and try to catch it. While they are distracted, piff your second ball with your right hand as hard as you can right between the eyeballs, they won't even see it coming?
