Bounce house goes berserk 4 stories above ground

We've all seen incidents of children being hurt or killed in bounce house accidents.

There was nearly another disaster over the weekend. A bounce house was carried away by strong winds during a child's birthday party!

Video taken by a neighbor in Niagara, New York, shows a huge gust of wind blow the bounce house -- which luckily was empty at the time -- high into the air.

How high? The house was blown into power lines about 40 feet off the ground, tangling with the wires and causing sparks to fly.
