I need an alarm clock that will actually get my adolescent son out of bed in the morning. Me going in and yelling at him - much as I enjoy doing it - is not working! And the alarms I've tried so far, he just sleeps through. I've seen ads for everything from a helicopter-type thing that spins into the air when the alarm sounds, to a "sonic bomb" alarm that makes noise and shakes the bed, to an alarm clock on wheels that jumps off the table and runs away when the alarm sounds. (Although the last one I don't completely understand - if it rolls far enough, then why can't you just ignore it and go back to sleep? ) Has anyone tried any of these - or do you have any suggestion for something even better?
