Last week a student noted that brass brads with the head down slide across a surface much better than brads with the head up and the sharp legs pointing down. We applied the principle to design a compass with 4 popsicle sticks using the small hole punch in a Crop-A-Dile tool. Note in the photo that the orientation of the brads on the right are facing head down to slide across the surface smoothly, while the brads on the left are facing up. Pushing down with two fingers on the left will cause our drawing compass to hold fast in place while we trace a perfect arc on the right with a pencil. The words "top" and "bottom" in the diagram refer to which sticks are on top when we assemble the compass.
