The bomb has a built-in timer and wires. There are 8 wires (in different colors) and 8 clips. Players have 1 hour (or ANY other time you choose) to remove the only correct wire. If they do this within 1 hour, they will hear a triumphal music. If not, they will hear the sound of a siren.
At the bottom of the fake bomb there is a magnet detector, which can be used to reload the device. Inside the device there are 4 buttons to set the timer. A micro SD card is installed in the fake bomb. Therefore, you can change the mp3 files.
