    I was making a minnow net to catch baitfish for my son. To make a cone you need a half circle of material out of mesh.

    Now in a 2D world the where there is no thickness this would be correct, if material can be added to fill gaps.

    In a 3D world, any round object with a hole and some thickness could be a straw. A washer is a straw by this logic
