I made this thing for my 10th grade research project, it's a homemade Ballista! I found it while cleaning out the shed, where it has languished for almost three years now... The bow is a 15' draw weight bow, for a child, and the markings down the length were for measuring how far we were pulling the drawcord. I kinda just wanna pick it up, nock an arrow and hold the thing sideways, and say with a very strong Italian accent
"Say 'ello, to mah lil fren!"
