In this instructable I will show you how to make a mini war machine similar to a catapult but it has a slightly different design. Instead of a rope or rubberband, it uses spring power. And instead of one firing arm it uses two.
Sorry if this has already been done but i didn't see it on the website.
I came up with this idea when I was bored in school and found a few paperclips in the floor.
I wanted to throw paper without being noticed; thus the paperclipapult was born.
