The Self Destruct Keychain is just a button. Press it and you'll hear a few drama-inducing beeps counting down (along with a flashing LED). Once the countdown is complete, there is a slight pause and then the sound of an explosion. Use your imagination and the Self Destruct Keychain to blow up your inbox, your boss, your computer, your whole office building, whatever you want. A great way to blow off steam with out really blowing up a thing - because sometimes that's all you need.
