Well it's 16mm wide, but it is not 16mm film. Double 8mm film has twice as many sprocket holes along the edge as 16mm film, so regular 16mm film will not work in a double 8 camera.
Also, Kodak discontinued 110 earlier this year, so you should probably save it for use in a 110 camera - considering double 8 is still available new and fresh, and 110 is likely gone forever. 110 also only has perforations along one side, not both, and the spacing is different than it is on 16mm movie film. Add to that it's c-41, there's really nothing you can do with it, except shoot it in a 110 camera.
And you can't flip the reel in daylight without ruining anything - you will ruin a couple feet of film each time! As for how the rest of the film doesn't get fogged on the edges, the spool is much deeper, and the image itself is well inward of the edge of the film - there is the sprocket area between the edge and image so any edge fogging generally won't fall in enough to effect the image.
A new roll of B/W fomapan double 8 costs something like $12, if you can find a lab that will process it, you might as well plunk down for the proper film.
