Huang Wei has invented an alarm clock which totally disables the option of hitting snooze repeatedly until you choose to remove yourself from your hung over semi-asleep state. 

To turn the alarm ON simply pull the pin and throw it. 

To stop it from going off in the morning, get up and replace the pin. 

While a genius concept - who would torture themselves with this thing every morning?

Eventually you'll want to pull the pin and throw it out the window as far away as possible from your bed room.
