Listen To Your Mother

Researchers have recently determined that children are far more likely to be roused from sleep in an emergency by the sound of their mother's voice than the sound made by a typical alarm. In a study involving 24 children between the ages of 6 and 12, 23 awoke quickly to the sound of their mothers commanding them to get out of bed (median time: 20 seconds). The regular alarm awoke only 14 of the 24 children, with a median awakening time of three minutes, which is an eternity in an emergency situation. At least one company already has a suitable product on the market.

Just don't set the alarm to say "clean your room!" There is a 100% chance that the command will be ignored.
