in my person opinion I think it can be done. my mistress has made me drop a steel toed boot tied to balls it weights like 2 pounds. if done properly big emphasis on if its done properly. if u do Deeside to do it proceed with caution because we r talk about your family jewels here. the way I would do it is slow let the bar grasp the ball sack don’t let it slam shut
and to all the people that say it snaps rats necks and backs it because of the force it produce if u slowly let it down u should be fine it will just be like a clamp
