A reactor serves to combust residual carbon in fine particulate matter, remove a contaminant from fine particulate matter, or change the composition of fine particulate matter. Expanded intercalated graphite worms communicate from a source through the charge inlet in the annular die cavity for depositing a charge of expanded intercalated graphite worms within the die cavity. Through the use of the method and system in accordance with the present invention, a user can view captured images without having to account for a rotation of the image-capturing device.
