Fallen Tree Incredibly Stands Back Up While Being Cut

Paul Firbas‘ friend had a fallen tree in his backyard after a storm. So what did he do? He grabbed his chainsaw and got to work, cutting the tree into manageable pieces to haul away. Amazingly though, once he cut off a large chunk from the top of the tree, the weight of the bottom of the tree pulled itself back up into its original upright position.

What sorcery is this? Gravity!
