How many times have you told your kids to stand in one spot while you go out for a night of drinking, only to come back and find that they're asleep on the floor or, worse yet, crying in some corner? Dozens, at least. Get some added help with the Lazer Trip Wire, a basic intrusion detection system that uses "harmless light beams" to keep your kids exactly where you left them. If they break the light barrier, an alarm will activate, notifying you that it's time again to remove dinner privileges for the next few weeks. Now that's good parenting.
