Man With Chainsaw Surprised by ‘Magical’ Tree [VIDEO]

A man is cutting up a fallen tree in his backyard when the tree appears to do something 'magical.' Of course, if you've had experience in using a chainsaw, you realize it's all a matter of physics.  But it's still baffling to watch.

This video was captured by Paul Firbas, Director of the Latin American & Caribbean Studies Center at Stony Brook University in New York.  See if you can explain what happened.
