NOTES
Title from title frames
Build your model ballista. Then construct two other types of catapult - the onager and trebuchet - designed such that they store the same amount of energy as your ballista. Field test all three to determine which throws a golf ball farthest. Will the winner be the weapon from the Hellenistic (ballista), late Roman (onager), or medieval era (trebuchet)? You may be surprised!
