Our prototype this year for hands on history was not a success. It wasnt a success because the object did not fly as far as we thought it would. The object went about 30cm foward and hit the ground straight. Although, this was not all a loss. From this we learnt that our arm did not fully swing through. This caused the object to fly towards the ground and hit an instant impact. Overall from the prototyoe we learnt several things eventhough the mini trebuchet failed.
