Distributed by Firebox.com Ltd., Shock Ball takes Hot Potato to another realm. This tennis ball-sized red danger orb made from soft PVC with little metal plates on it glows green from the inside until ... ZAP! The light randomly turns red, and a wicked electric shock courses through whoever has the ball in his hand. There follows much screaming and lots of laughter ... by everyone but the shocked. This is the hippest thing around London. The rechargeable ball makes a great party game. Or, for those of a more masochistic bent, it can be played alone. Rob Fleischer, who does publicity for distributor Firebox, said “a battery version of Shock Ball will be shipping in late summer, early fall.”
