Lego! I have alot of engineering friends that attribute playing with Lego as a kid as the reason they got into engineering. Although im now a design engineer, I definately saw myself as a medieval structural engineer back in the day. Castles being my speciality and as fun as building them were it was the destruction of them that was the greatest thrill. So introducing the rubber band powered Seige catapult simply print out put together loop on a standard rubber band and your ready to breach the castle walls/ your colleagues desk. Recommended ammo are marbles and your sisters barbies head. Hope you like it Edit V5: increased tolerances for easier printing
