This is a picture of the Goose II. Team member, Zach chose the name because when he was building it, he thought that one of the pieces looked like the head of a goose.
Building the trebuchet went smoothely except for one problem- the pivot. We couldn't seem to find a dowel large enough to do the right job. Eventually, we came up with the idea of using the handle of a shovel. Once cut to size, the new 'dowel' now worked perfectly as the pivot for our trebuchet.
When we tested the trebuchet, Zach functioned as the counterweight and pulled the trebuchet back- when released the projectiles (pieces of concrete) went approximately 300 feet.

When building our trebuchet, we got helps and hints from the Ingenium, a web page by Kevin Geiselman.
