Pneumatic Bed Shaking Alarm Clock
This is a bed shaking alarm clock on steroids! This is even more jolting than my Fire Alarm Bell Alarm Clock! It uses two sources of air, a huge air compressor under the basement stairs and air from the car compressor. A computer controls a valve which starts bed shaking action. See the video below where it is tried out at a radio station. Thanks for the tip Stagueve.
