This is a really genuine idea for an alarm clock. The drinking glass is placed on the coaster-like clock and rests on tiny spikes, allowing it to vibrate indiscreetly when hit gently by a hammer through a hole in the top of the clock. You can alter the pitch of the alarm tone. The more water, the lower the tone. The alarm is activated by placing the glass on the clock and turned off by lifting it up. The slow rhythm and varying tone of glass followed by a sip of water creates the start of a calm and relaxed day.
