The Defusable Alarm Clock works just like any other alarm clock, with one BIG exception. When you press the big red button to turn off this alarm, a countdown begins. You then have 10 seconds to figure out which wire to cut (or pull out from the terminal). One wire will stop the countdown, two have no effect, and another will detonate the device immediately. And before you get too comfortable with your skills, take note: “each wire is randomly assigned when the detonate button is pressed, so it’s a new challenge every time.”
