So I set about getting my slingshot fix from Youtube. I ran across Joerg's "Little accident" video. Looked really painful, and I hope he's okay by now. I was horrified by how hard it hit him, even after the ricochet, it still had a lot of energy left. So we see how research and development of slingshots can carry a certain amount of risk in that anything can happen when left to chance. Sometimes fate has it's way with you, no matter how much effort is placed on precaution. I also found it ironic that this happened with a slingshot he was developing from a safety aspect. It was designed to protect the hand from shots leaving the shooter and even a shot that would possibly return and strike the hand. In reviewing the footage, I can plainly see it was really a freak accident. Not much anyone could foresee. In hindsight though, I can suggest angling the backstop slightly to one side. If the projectile didn't make a dent in the backstop, it might have deflected it farther away from Joerg say off to his left since the camera person was to his right. Again, I hope you are okay Joerg. I thank you for making all these informative videos, and very much respect your decision to post that video for the rest of us to learn from.
