This thing's been loads of fun. We built this to hurl anything from paintballs to smaller snowballs, but it can be scaled easily with a few tweaks. As of presentation time we were throwing paintballs 100 meters at about 30 meters/second with a 10 kilogram counterweight. The hook should hold around 40 kilograms, giving us a bit more punch. Might have to try the snowballs this weekend
