Here's a neat idea that just might prevent a nasty fall!

Here’s how the Safety Socket works. You plug your appliance AC cord into the Safety Socket and the Safety Socket into a wall outlet. If someone walking or running trips over the power cord, it disconnects instead of causing a fall! Once disconnected, it’s easy to just snap the magnetic socket back together to turn the appliance power back on. The patented breakaway outlet is designed to prevent tripping over electric cords, and to minimize the risks of accidents, costly repairs, and broken appliances. It could be a great help in households with children and/or the elderly. I asked the company if there was a way to judge exactly how much pressure was needed to cause the Safety Socket to disconnect. A spokesman at the Hardware Show explained that if there were enough pressure to cause a fall, the Safety Socket would disconnect first and avoid the fall. My guess you really can’t figure out exactly what will happen in every case, but it’s a great safety assist for less than $20. (Plus S&H.)
