Take the arm and put it in the slots on the trebuchet. Put the projectile into the green pouch and place the string around the end of the rod. Stick the pin through the three eyelets on he arm and base of the apparatus. Then load the counterweight onto the end of the arm near the wheels. Pull the string to launch the trebuchet.
Do not attempt to catch the projectile. Stay out of the projectile’s path. Stand clear of the swinging arm. The trebuchet is capable of flinging projectiles 20 meters or more, so choose projectiles and counterweights wisely. Safety glasses must be worn when operating.

A model trebuchet is used to hurl projectiles using counterweights.
