An out-of-control playground swing has got families and police in Argentina spooked. And via YouTube, millions of others too!

The swing apparently rocks back and forwards without being touched - and anxious parents have decided the playground must be haunted. In fact, local Police were worried enough to call in physics professors. Spookily even they have been unable to explain the mystery motions.

The swing can keep moving continuously for ten days before suddenly coming to a halt, it has been claimed. Evidence of witchcraft or just a strong wing - watch the video and decide for yourself.
