i have a friend in Africa that is 80% to 90% as good as that guy, they call them "catapults" in Zimbabwe, my friend makes them you of a Y shaped branch and old tire inter-tube. I have seen him hit tiny birds in the head with it 2 or 3 times in a row, I tried it and hurt my self, who knows where the stone went. LOL. He has been playing with them since he was 5 or 6 he said, he is 35 now. He is a professional hunter and when your in the bush, with absolutely nothing you find ways to entertain your self, thats where he grew up and he is like the guy in the video, I couldnt believe it when I saw it. He sucks at pool LOL. His friend made one as well and wasnt as good but still could hit what he wanted more often than not. They laughed at me:sorry:. They held it at a angle that enabled them to aim, He said its all in the timing to be accurate, same with pool. The rubber in the video is much better and faster than my friends. Its amazing what can be done if you take the time to do it.
