Here's the result of a little experiment I did with my hunting partner. We were clearing a shooting lane from a tree stand, removing dead limbs from high up on a pine tree. By tossing a rope over the limbs one of us on each end, we could yank on the rope and break the limb off and repeat the process until all the offending branches were removed. We were on the side of a steep hill.
I wondered what would happen if, when we both yanked on our respective end, one of us let go...Since my partner didn't know about the experiment it was left to me to yell "pull!" then release my end. You see consequence of this scientific research.
