The Revive Alarm Clock by Kai-ning Huang and Yu-Yang Chen is an interesting concept clock that aims to wake you up and help keep your bowel movements regular. No fiber required.
The Revive Alarm Clock works in conjunction with a glass of water. The water is heated by the alarm clock 30 minutes before your alarm is to go off. The alarm won’t start ringing until you remove your glass of warm water, which will help you start your day the right way, so to speak.
