Mangonel

I made a Mangonel. A Mangonel is a contraption. (here is a pic)

The Mangonel works like this. There is a spoon, you crank it down . And then you stretch the rubber band  attached to the spoon . You put ammo on the spoon. Then you release crank1.

The Mangonel was first used about 2,500 years ago.
