DISCLAMER WARNING!!!! GRAPHC! BLOOD AND STUFF
I have seen this guy on you tube before he has a channel and he builds high power Sling Shots.
I had planed on building one of his designs with my young nephews for some back yard fun. After watching this video of what can happen I think I will just stick with Hide and Seek for fun.
The Blood comes in the end of the video when one of the Ball bearing he is using bounces back at him and nails him right in the head. I must say the video is shot very well and its amazing at what it captures. You have been warned! dont watch if you cant take a open wound to the head
