YellowJacket's $140 iPhone case has a built-in battery-powered stun gun that produces what the company describes as a "painful sting."
Charge the case and press the activation button and you are able to shoot 650 kilovolts of electricity through someone's body. The case, which has been available for the iPhone 4 and 4S, is going to be available for the iPhone 5C and iPhone 5S in a couple of weeks for pre-order and then will ship in time for the holidays, according to company's co-founder and president Seth Froom.
