There's nothing quite as nerve-wracking as playing pass the parcel with a time-bomb, or quite as much fun. Shockball is basically catch for the brave and the hard. This red metal-studded ball contains a hidden wickedness - that is rather given away by the name. Turn it on and then start throwing it to one another and at some random point in the all too near future, the person catching it will get zapped. You never know when it's going to 'go live', so it turns catch on its head - instead of worrying whether or not you can catch the ball, now you'll worry about what will happen if you catch the ball. This rubber-coated land mine has been the cause of lots of shrieks in the office - though oddly they seem to come before the person's even caught the thing. There's nothing like a bit of anticipatory fear to spice up a game!
