F is for Fan

Thanks to KangaZu for hosting MonoMonday this month and coming up with the challenge of the last ‘F’ in February.  I think I’ve got that right?
 
So ‘F’ is for fan.  I had a heck of a lot of trouble getting the shutter speed right to stop the fan-blades, and if Mrs W hadn’t come up with the idea of switching the power off I think I would still be at it . . .
