Trebuchet video
I have taken a video of the trebuchet that I talked about in this post. I also have a few more pictures.
This is the path that the apple took. I have merged together several frames of the video and highlighted the apple in each one. The path looks a little odd because of a combination of a strange camera angle and the apple bouncing off the wall.
Here is what is left of the apple that was big enough for me to pick up. Some other apples were completely destroyed.
This two pictures show the joints in greater detail. Notice the reinforcing metal rings.
