The Bob said:What sort of ideas do you have? Are you thinking of using elastic bands and wood or a spoon and a mechanised launcher?
Please throw us a bone on what you have to go with.

A ballista is a type of ancient weapon that uses torsion to launch projectiles such as arrows or, in this case, a golf ball. It works by using twisted ropes or sinew to store energy that is released when the ropes are suddenly untwisted, propelling the projectile forward.
The main materials needed to build a ballista are wood, rope or sinew, and metal for the trigger mechanism. The type of wood used should be sturdy and flexible, such as yew or ash, and the ropes or sinew should be strong and able to withstand tension. The metal trigger mechanism can be made from scraps or purchased from a hardware store.
The range of a ballista depends on many factors, such as the angle of the launch, the strength of the ropes or sinew, and the weight of the projectile. However, on average, a 25m ballista can launch a golf ball up to 100-200 meters.
Building and using a ballista can be dangerous, especially if proper safety precautions are not taken. It is important to follow instructions carefully and wear protective gear while constructing and operating the ballista. Also, make sure to use the ballista in a safe and open area away from people or buildings.
Yes, a ballista can be used for various purposes, such as launching other types of projectiles (such as arrows), participating in historical reenactments, or for educational demonstrations. However, it is important to always use caution and follow safety guidelines when operating a ballista for any purpose.
